           For other support sites take a look at SUPPORT.DMP

*** ---------------------------------------------------------------------- ***

Version 4.00    Major update                            March 22nd, 1995
                Careware release

        * DMP is now *careware*. Read the end screen for more information.
        + Major DSMI sound system update, new sound card drivers.
        + New easy sound setup.
        + File selector with module name database.
        * DMP and DMP32 distributed in the same packet.
        + Now also DMP32 supports digital effects.
        - Quality mode is now always on for 8-bit cards.
        + Support for GUSMAX codec.
        - No more support for LPT DACs or PC speaker.
        - Archiver support is gone for this version. Next versions will
          have a new system as the old one didn't work very well.
        + You can scroll instrument list with PgUp/PgDown.
        + Jump to previous module is now possible with 'B'.
        - VGA palette bug fixed.
        - S3M note delay bug fixed.
        - Many minor bugs fixed.

*** ---------------------------------------------------------------------- ***

Version 3.01    Bug fixes                               July 3rd, 1994

        - SB autoinit mode didn't work with DSP version 2.00 (like PAS
          SB emulation and some other compatible cards).
        - GUS player had too long delay loops.
        - WSS init routine has been changed.
        - The old Aria interface is back.. couldn't test is, though.

*** ---------------------------------------------------------------------- ***

Version 3.00    Digital effects                         June 19th, 1994
                GUS bug fixes

        + DMP now has reverb/echo and filter effects to give you even
          better quality music. These effects are user definable
          (in DMP.INI) and are available for all sound system except
          GUS. See DMP.DOC for deeper discussion on these effects.
        - Fixed an initialization bug in GUS player. The init code
          couldn't handle situations when both GUS DMA channels
          shared the same channel, or when both IRQs used the same
          interrupt.
        + New help screens for keys and command line parameters.
          "DMP -h" shows only the parameter help, and pressing 'H'
          while in DMP shows only the key help screen.
        + Autogain setting for 16-bit quality mode. This feature changes
          the default volume settings according to the number of channels
          in the module.
        * I'm not accepting new DMP support sites anymore. There are
          already over 100 support sites around the world and that's
          enough :)

*** ---------------------------------------------------------------------- ***

Version 2.95    GUS changes                             June 14th, 1994
                More free memory in DOS shell

        - Fixed tremolo effect
        - Less UltraClicks
        - New DMA loading method for GUS
        + Optional GUS timer based playing (-gt to disable GUS timer)
        + Checks for GUS memory allocation
        - Less memory fragmentation -> more free memory in DOS shell
        + Solo track mode (press 'S' to solo/unsolo)
        - Fixed panning bug with 16-bit quality mode

*** ---------------------------------------------------------------------- ***

Version 2.94    Many player bugs fixed                  June 8th, 1994
                SB/SBPro/SB16 work now in autoinit mode

        - Due to a small bug in the player, retrig, notecut, delaynote
          and some other commands were not executed corrected.
        - SB/SB Pro and SB16 now use autoinit mode if possible. This
          gives better sound quality with less clicks.
        - Bugs fixed in S3M loader (vol+tone and vol+vibr were reversed)

*** ---------------------------------------------------------------------- ***

Version 2.93    669 loader fixed                        June 2nd, 1994
                SB Pro left-right bug fixed

        - A tiny, tiny bug in 669 loader caused erronous memory allocations..
        - SB Pro (and clones) should now play left and right correctly

*** ---------------------------------------------------------------------- ***

Version 2.92    New 16-bit quality mode                 May 26th, 1994

        + New! Quality mode for 16-bit cards. With the new quality mode
          you can get much better dynamics with multi channel modules.
          This method uses a 32-bit intermediate mixing buffer and clips
          the data into 16-bit output format. Using too high volumes
          will cause more clipping which degrades sound quality a bit.

          Usage: DMP -q -aXXX module

          where XXX is the gain (amplification value).
          32 = normal volume
          64 = 2 x normal volume
          100 = 3.125 x normal volume
          etc.

          Maximum usable amplification is around 700 (which means
          2100% amplification, quite loud!)

*** ---------------------------------------------------------------------- ***

Version 2.91    Many bugfixes in various parts          May 23rd, 1994
                New commercial licensing system for DSMI

        * Maintenance release, lot's of bugs fixed.
        * This one wasn't officially even released...

*** ---------------------------------------------------------------------- ***

Version 2.90    Better GUS compatibility                May 7th, 1994
                Loader fixes

        - GUS player now uses PC timer instead of GUS' own timer. This
          will cure some problems users have had with DMP.
        - Also new technique for GUS DMA download.
        + Better S3M loader.
        + FAR loader can now handle >64 row patterns
        - Fixed the SB Pro detection bug

*** ---------------------------------------------------------------------- ***

Version 2.89    New detection routines for SB           April 3rd, 1994
                Optional DMA for GUS

        - New detection routines for SB family. These routines use
          the BLASTER environment variable (if available) to detect the
          presense of Sound Blaster (Pro, 16). If BLASTER is not available
          the old hardware detection routines are used instead.
        + You can now use either the old byte-by-byte transfer method or
          the new DMA transfer. Parameter '-g' enables the non-DMA
          method.
        - Fixed a bug in AudioTrix Pro (and Windows Sound System) exit
          routine that caused incorrect IRQ and DMA channel to be active
          after exit.
        * Another new Internet mail address, you can now reach me at:

                otto.chrons@cc.tut.fi           ( easier to remember ;) )
                c142092@lehtori.cc.tut.fi
                c142092@proffa.cc.tut.fi

*** ---------------------------------------------------------------------- ***

Version 2.88    Loaders fixed                           March 20th, 1994

	- GUS DMA bugs fixed. If you had differing DMA channels for
	  recording and output, DMP would lock up.
	- MTM and FAR loaders work now significantly better
	* New Internet mail address:

		c142092@lehtori.cc.tut.fi

*** ---------------------------------------------------------------------- ***

Version 2.87    GUS bug fixes                           March 13th, 1994

	- Samples are now downloaded into GUS using DMA
	- GUS player bugs fixed (skipped notes, inaccuracy)
	- With PAS the DMA transfer was not stopped after exit -> slow down
	* Released a 32-bit version of DMP. Check out for DMP/32

*** ---------------------------------------------------------------------- ***

Version 2.86    Bug fixes                               February 26th, 1994
                New batch features

	- Fixed the quality mode bug in 2.85 that caused lockups
	+ New commandline option '-X' enables quiet screen mode. In this
	  mode DMP writes absolutely NOTHING to the screen. Great for
	  batch files.
	+ Error level support for '-Wcmd' option. If your spawned program
	  returns with error level 68, DMP exits immediately. Meant to be
	  used within batch files...
	- You now have 1 second to decide whether to play corrupted modules
	  or not. Press 'N' or ESC if you don't want to play the module.
	- Fixed the MTM loader's heap corrupting bug.

*** ---------------------------------------------------------------------- ***

Version 2.85    Bug fixes				February 22nd, 1994

	* Skipped 2.84 because a fake version had that version number
	- Fixed the division by zero bug with SB16
	- Corrupted modules are now played

*** ---------------------------------------------------------------------- ***

Version 2.83    SB 44kHz mono support (SB Pro, SB 2.00)	February 14th, 1994
		AudioTrix Pro support
		Amplifying bug fixed

	+ SB and SB Pro 44kHz support. Use -m with SB Pro to force mono.
	+ AudioTrix Pro support (use WSS options)
	  DMP -c8 -d3 -p530 module
	- Lots of internal changes for better code.
	- Fixed the amplifying bug (parameter -aXX)
	- Another S3M volume slide bug fixed

*** ---------------------------------------------------------------------- ***

Version 2.82    Faster mixing				January 31st, 1994

	+ Rewritten mixing routines are now about 25% faster on my 486/33
	- PAS DMA bugs fixed (hopefully). Caused flipped L/R channels, or
	  noise.

*** ---------------------------------------------------------------------- ***

Version 2.81    S3M bug fixes                           January 24th, 1994
		New customization options
		Player bugs fixed

	- S3M volume slide bug fixed
	- Pitch bending bugs fixed (mainly in S3Ms)
	+ New options in DMP.INI
	  * VGA hardware palette
	    - now you have total control over DMP's outlook
	  * Channel ID characters in instrument list
	    - you can easily change the IDs to digits or any other characters
	  Check out the DMP.INI for these two features
	- some GUS bugs fixed, mainly with 14+ channel music

*** ---------------------------------------------------------------------- ***

Version 2.80    GUS bug fixes                           January 17th, 1994
		25/50 row display

	- Some GUS bugs fixed: new volume table, lot less "missing" notes,
	  some IRQ bugs fixed
	+ You can now switch the screen to 25/50 lines by pressing 'Z'
	  Or you can use command line option '-Z25' or '-Z50'

	  BTW, my birthday is on the 30th of January (I'll be 21) so if
	  you haven't sent the "I like DMP" card, now is the right time!

*** ---------------------------------------------------------------------- ***

Version 2.79    FAR loader                              January 2nd, 1994
		Bug fixes

	+ DMP now loads Farandole Composer's FAR modules
	- some bugs with MOD/MTM loader fixed
	- "Cmdline" in DMP.INI works now correctly

		     HAPPY NEW YEAR TO ALL DMP USERS!

*** ---------------------------------------------------------------------- ***

Version 2.78    Bug fixes                               December 11th, 1993

        - Fixed a bug that caused delayed playing on some tracks (2.74-2.77)
        - Added a new feature to MOD/MTM loaders to make it more
          compatible with ProTracker
        - Fixed the bug with multiple file archives
        - Instrument numbers are now alphabets.

*** ---------------------------------------------------------------------- ***

Version 2.77    Bug fixes                               December 6th, 1993
                Monochrome screen
                Real volume bars for GUS

        - A tiny bug in GUS heap routines caused weird errors
        - New volume table for GUS -> less clicks
        + Real volume bars for GUS
        + Monochrome screen support in DMP.INI (check it!)

*** ---------------------------------------------------------------------- ***

Version 2.76    DMP.INI                                 December 6th, 1993
                Archive support (general)
                Bug fixes

        - Some bugs with Timer Service fixed
        - MTM loader bugs fixed
        + DMP now has a config file: DMP.INI. Check out the descriptions
          in DMP.INI for more information
        + You can now play packed modules. See DMP.INI for information
          on how to use your favourite packing program with DMP

*** ---------------------------------------------------------------------- ***

Version 2.75    Bug fixes                               December 3rd, 1993

        - New reset routine for GUS
        - A bug in S3M loader fixed
        - Many internal changes for forthcoming DSMI/32
          which is a 32-bit flat model (Watcom C/C++) version of DSMI.
	  Already works with GUS
        - Better MTM support (upto 32 channels now)

*** ---------------------------------------------------------------------- ***

Version 2.74    MTM support                             November 28th, 1993

        + DMP now loads and plays MTM modules created with MultiTracker
        * I had to skip 2.73 because some lamer had done a fake 2.73 (which
          didn't even work..)
        - New postcard address
        - LOTS of internal changes (for forthcoming DSMI/32)

*** ---------------------------------------------------------------------- ***

Version 2.72    Bug fixes                               November 13th, 1993

        - Uhh, a major bug in CDI caused crashes with other soundcards
          than GUS (and maybe even with GUS)... I wonder when I learn to
          test DMP propely before releasing it!
        - Fixed a bug in S3M loader that caused the last instrument not
          to play at all.
        + Now you can use surround in your own modules too! Just use the
          command 8 (normally unused) with parameter A4. If you want
          regular panning, use values 0 for left, 40 for center, 80 for right.

*** ---------------------------------------------------------------------- ***

Version 2.71    Bug fixes                               November 1st, 1993

        - Samples are now loaded into GUS using the old non-DMA method.
          It seemed like the DMA routine was causing most of the problems
          on various machines. I have optimized the byte-by-byte downloading
          function, so it doesn't take too long on slower machines either.
        - Some timing bugs with GUS fixed.
        + Option -Wcommand lets you immediately shell to DOS after the module
          starts playing. It will also run the optional 'command'.

*** ---------------------------------------------------------------------- ***

Version 2.70    Murphy's law...                         October 10th, 1993

        - Correcting one bug creates two new bugs... GUS didn't set
          the correct channel count -> too high play frequency
	- Reset code should now finally work...
        - 669 loader tempo bug fixed
        - DMA bug with normal sound cards fixed (caused static)

*** ---------------------------------------------------------------------- ***

Version 2.69    Stereo DACs fixed (hopefully)           October 9th, 1993
                GUS reset bugs fixed

        - There was a small bug in stereo DAC code that prevented
          stereo output. Now fixed.
        - New reset code for GUS should get rid of those lock ups with GUS.
        + New device numbers for PC Speaker/Stereo DACs (10,11 & 12)

*** ---------------------------------------------------------------------- ***

Version 2.68    Stereo DACs                             October 3rd, 1993
                Bug fixes

        - There was a serious portamento bug in 2.67 which is now fixed
          (I should've tested it more carefully before releasing...)
        + Support for stereo DACs. Use following options to enable
          them:

          DMP -c6 -d1           <Dual DACs on LPT1 & LPT2>

          DMP -c6 -d2 -p378     <Stereo-on-1 on LPT1>

          NOTE! I haven't tested these (cause I don't own 2 Covox style
          DACs or Stereo-on-1 DAC) so please report any errors/bugs
          to me.
        - Some internal bugs fixed

*** ---------------------------------------------------------------------- ***

Version 2.67    GUS bugs fixed                          October 3rd, 1993
                New SB16 detection routine
                Better S3M compatibility
                Channel inc/dec removed

        - Some GUS IRQ bugs were fixed.
        - New SB16 detection routine reads IRQ/DMA values directly from SB16,
          no guessing anymore. Test it! (I haven't!!)
        - Better S3M compatibility (portamento works correctly).
        - You can't increase/decrease channel count anymore, well there
          is no need for it either because you won't get those cracks
          with panning anymore.

*** ---------------------------------------------------------------------- ***

Version 2.66    GUS bugs fixed                          September 26th, 1993

        - DMA transfer should now work with most motherboards due to
          reduced transfer speed.
        - GUS is now reseted so that line output and input are enabled
          (2.65 didn't enable even output!)
        - Track pause and resume work with GUS
        - Louder volume with GUS

*** ---------------------------------------------------------------------- ***

Version 2.65    Surround Sound!                         September 19th, 1993
                Bug fixes

        + Surround sound is implemented! Pressing the 'U' key sets a
          track into surround channel. If you have a Dolby Pro Logic
          Surround Sound Decoder you can hear the sound coming from
          your surround speaker, but even without this decoder you
          get a more "spacier" effect (similar effect found on many stereo
          TVs to enhance mono sound). Use command line option -n100
          to set all tracks to surround mode.
          NOTE! Does not work with GUS!
        - Playing with SB/SB Pro corrupted the higher part of ECX register,
          now it's corrected.
        - GUS loops play now "clicklessly"
        - GUS' mixer settings are not altered anymore so if you have eg.
          line output enabled it will stay that way.

*** ---------------------------------------------------------------------- ***

Version 2.64    Bug fixes                               September 13th, 1993

        - Fixed a bug with high DMA channels and GUS
        - Small loops play now correctly

*** ---------------------------------------------------------------------- ***

Version 2.63    Bug fixes                               September 11th, 1993

        - Some clicks removed from GUS playing.
        - Fixed the problem with loading samples (GUS).
        - Samples are now loaded to GUS using DMA. This method gives a
          faster and more solid transfer. It also reduces some clicks
          caused my byte-by-byte downloader. May not like QEMM if your
          DMA buffer is small.

*** ---------------------------------------------------------------------- ***

Version 2.62    GUS support, getting better!            August 29th, 1993
                Fixed a few bugs

        - GUS player seems to working very well now.. still some troubles
          with loading samples after playing many modules, but I'm working
          on it.
        - Fixed a bug in the 669 loader

*** ---------------------------------------------------------------------- ***

Version 2.61ß   GUS support, better                     August 16th, 1993

        - Some improvements to GUS player. A lot less ultraclicks
          and it should work on any GUS (hopefully!). Please report
          any bugs/incompatibles via e-mail.

*** ---------------------------------------------------------------------- ***

Version 2.60ß   GUS support                             August 8th, 1993

        + GUS is now supported, somehow. I know, it's full of "UltraClicks"
          and it doesn't sound right, but this is just a beta version.
          If you know what could be going wrong (I know *many* things
          already), please send me some e-mail about it. I try to remove
          those clicks as soon as possible, but right now I just wanted
          to see it working.

*** ---------------------------------------------------------------------- ***

Version 2.55    Bug fix                                 July 11th, 1993

        - Two previous versions didn't work with SB16, now fixed.
        - Some little things with WSS changed...

*** ---------------------------------------------------------------------- ***

Version 2.54    Bug fixes                               June 27th, 1993

        - WSS support did not work in 2.53 because of a very small bug :(
        - 2.53 REQUIRED Virtual DMA Services to work propely due to
          an erronous detection routine. Now it should work fine.

Version 2.52    Bug fixes                               June 8th, 1993
                DMP.FAQ
                Default panning

        - lots of small bugs fixed in various routines...
        + If you encounter problems with DMP, read the DMP.FAQ
          as it contains Frequently Asked Questions about DMP.
        + If you're using headphones with a stereo card, you might
          want to use the default panning feature, which sets panning
          on left and right channels closer to the middle. Use option
          -nXX to enable default panning.

*** ---------------------------------------------------------------------- ***

Version 2.51    Many bugfixes                           May 28th, 1993
                New Quality mode!

        - bug fixes in EMS-, mixing- and DMA routines
        + Quality mode is now better than ever! Music plays
          a lot louder and is clearer too.
        - No more autocalibration, because it didn't work on
          some machines.

*** ---------------------------------------------------------------------- ***

Version 2.50    Bugfixes                                May 25th, 1993
                EMS support
                Autocalibration
                Utlities are gone

        - some bugs in S3M loader fixed, and no more note shifts!
        - Aria support works now better.
        + DMP can now utilize EMS memory for samples. So you can
          play really large MODs with DMP and still have lots of
          DOS memory! Option -b disables EMS usage.
        + Autocalibration adjusts DMP's sampling rate to match the
          REAL sampling rate of the sound card.
        * GRAB.EXE, VIDEOMEM.COM and batch files for ripping S3Ms
          are now history. If you want them, fetch an older version

*** ---------------------------------------------------------------------- ***

Version 2.46    Bugfixes                                May 18th, 1993
                Aria card support
                Support sites?

        + New Aria-based sound cards are now supported! You can play up
          to 44.1kHz with 16-bit stereo quality!
          If autodetection fails, use -c7 and other parameters...
        - The portamento/vibrato/arpeggio bug in 2.45 fixed.
        - Theoretically speaking, the S3M loader now converts modules
          incorrectly, but in practise they sound a lot better ( a half
          note shift upwards makes wonders.. :)

        * Do you have a BBS and would like to become official support
          site of DMP? Read the included SUPPORT.DMP text file for
          more info.

Version 2.45    Full panning                            May 14th, 1993
                Monochrome support

        + DMP can now be used with monochrome screens
        + On stereo card, you can now pan any channel to any position.
          You might have to add new channels, if you get cracks. And
          remember that using panning takes about 80% more processor
          power!

*** ---------------------------------------------------------------------- ***

Version 2.44    Bugfixes                                May 12th, 1993
                PC speaker support
                DAC works better with memory managers

        - Corrupted MOD files are now played more correctly. Previously
          the last instrument was not converted into unsigned format.
        + You can now use DMP with PC speaker! Use parameters "-c6 -p42"
          to enable speaker support.
        - DAC (and speaker) work now a lot better with memory managers
          such as QEMM,MAX386 and EMM386.
        - Little bugfixes in S3M loader.

*** ---------------------------------------------------------------------- ***

Version 2.43    Bugfixes                                May 11th, 1993
                Channel panning
                Real volume bars

        - Fixed bugs in 669 and S3M loaders
        + Channels can be panned independently with keys L,M and R. If you
          get cracks in the sound, add more channels with ')'. Select channel
          with up/down arrows. Try panning drums to middle, sounds great!
          Of course, all this works only on stereo cards :-)
        - M2AMF now converts 669 modules correctly.
        + Volume bars are now calculated using the real sample data,
          press 'V' to switch between new/old mode.
        + SB Pro's filter is now off by default -> clearer sound

*** ---------------------------------------------------------------------- ***

Version 2.42    Bugfixes                                May 10th, 1993
                Filter switch for SB Pro
                M2AMF supports 669 and S3M
                Tempo settings

        + Now you can convert your S3M and 669 files into AMF format.
        + If you want to have clearer sound on SB Pro, turn off the
          filter by pressing 'F'
        + You can also change the tempo module is playing by pressing
          [,],{ or } keys. '[]' affect speed, and '{}' affect BPM tempo.
        + Pressing '(' adds and ')' removes one channel. You should clearly
          hear how this affects sound quality.
        - Some bugs fixed in module loaders

*** ---------------------------------------------------------------------- ***

Version 2.41    Bugfixes                                May 9th, 1993
                New utility
                Amplifier

        - Fixed note portamento
        - S3M loader is now a lot more compatible.
        - Some outlook bugs fixed, like help screen and that blinking
          bug after returning from DOS shell.
        * VIDEOMEM is a small utility that transforms 96kB of video
          memory into conventional memory, so you can play bigger
          modules with DMP. Works with other non-graphic software, too.
        + You can now amplify playing with command line switch -a.
          Normal value is 31, but be aware that amplifying may cause
          some nasty cracks if volume goes too high. But amplifying
          is helpful if you're playing 8+ channel MODs on 8-bit cards.

*** ---------------------------------------------------------------------- ***

Version 2.40    Bugfixes                                May 7th, 1993
                Scream Tracker 3.0 support
                Composer 669 support
                New outlook

        - Some bugs with DMA fixed (again :-) )
        + Now you can play S3M modules. Three batch files included
          for easy extraction of modules from Future Crew's demos.
          *NOTE! Not all S3M commands are implemented.
        + You can also play 669 format modules, if they fit into memory :)
        - A small bug in STM loader fixed.
        + Little changes in outlook.. You may have to use 50 line mode
          if you want to see all the instruments in some modules

*** ---------------------------------------------------------------------- ***

Version 2.34    Bugfixes                                April 20th, 1993
                Mailing list

        - Bugs with DMA fixed.
        + DMP now returns an errorlevel of 1 if exited via ESC and
          0 on normal exit (only if looping is disabled).
        * If you want to get new DMP automatically and have Internet
          access, you can join DMP mailing list. Just send a message

        - A bug in Retrig command (only in 2.32) was fixed
        - Now the 8-channel FastTracker MODs play OK, previously
          there were problems with channels 7 and 8.
        - False Windows detection corrected (occured if you had an
          environment string "WINDIR")
        * And remember: DSMI IS AVAILABLE!

*** ---------------------------------------------------------------------- ***

Version 2.32    Bugfixes                                April 9th, 1993
                New features

        - A bug with Tremor command fixed
        + Now you can disable ProTracker extended tempos for those
          old modules (switch '-e')
        - Some problems with 8-bit DMA in Pro Audio Spectrum 16 fixed

*** ---------------------------------------------------------------------- ***

Version 2.31    Bugfixes                                March 16th, 1993
                New features
                * DSMI IS AVAILABLE *

        - Some bugs with false PAS detections are now fixed
        + You can shell to DOS with Covox, up to 64kHz!!
        * DSMI is finally available! Read the README file for
          additional info...

*** ---------------------------------------------------------------------- ***

Version 2.30    Bugfixes                                March 6th, 1993
                Covox support is back!
                Faster

        - DMP 2.20 failed to load any 15 instrument MODs. Now fixed.
        + Support for Covox. Use parameters '-c6' and '-p' to enable
          Covox (DAC) support at any port address. See revision entry
          for 1.41 for additional info... Covox supports rates up to
          44kHz.
          NOTE: Covox support doesn't work well if you have a memory
          manager like EMM386 or QEMM386 installed.
        + On a 386SX (or other non-cached 386) DMP should be about 10%
          faster :)
        * Thanks for Pieter Immelman for helping out with UNIX
          mail-listserver for DSMI/DMP

*** ---------------------------------------------------------------------- ***

          used command line arguments, for example:
          SET DMP=-s30 -m -o
        + Volume can be changed with + and -
        - UMB support is gone :-( Use PMP (Protected Module Player) to
          play REALLY large modules
        * Changed the method for detecting Pro Audio Spectrum cards.
          Please test on PAS and PAS+

*** ---------------------------------------------------------------------- ***

Version 2.11    MOD loader bugfix                       February 22nd, 1993

        - Some MODs used highly NON-STANDARD period values, so the
          change I made in version 2.02 caused erranous loading. Now
          the loader should handle any MOD.

*** ---------------------------------------------------------------------- ***

Version 2.10    ProTracker tempo support                February 21st, 1993

        + Support for ProTracker's extended tempos has been added.
          Both regular and ProTracker-tempo (in BPM) are now shown on
          screen.
        - Some minor bugfixes.

*** ---------------------------------------------------------------------- ***

Version 2.02    Bugfixes                                February 15th, 1993

        - Bug in the MOD loader caused erranous volumes when instrument
          changed.
        - When using a 16-bit soundcard, DMP could cause machine lock-up
          if a 386-program was run in DOS shell. Now it won't.
        - Help screen showed wrong information about '-u' switch

*** ---------------------------------------------------------------------- ***

Version 2.01    UMB support defaults to DISABLED        February 9th, 1993
                Bugfix

        - Because of the many reports of memory problems with UMB
          options, it now is disabled by default.
          Use '-u' to ENABLE it, previously that switch DISABLED it!
        - Pausing module with 'P' caused computer to lock up with
          a SB Pro. Now it's fixed.

*** ---------------------------------------------------------------------- ***

Version 2.0     DMPMT and DMP combined into one .EXE    February 7th, 1993

        * DMPMT no longer exist as a separate executable as it's
          functionality has been embedded into DMP.EXE. DMP now
          automatically detects DesqView and Windows and changes
          to DMPMT mode if either is detected. You can also force
          DMPMT mode with '-t' parameter which also accepts
          buffer size like '-t30000'.

*** ---------------------------------------------------------------------- ***

Version 1.95    UMB support                             February 6th, 1993

        + DMP fully utilizes all available upper memory. Now you have
          more memory available in DOS shell and you can also load
          bigger modules.

*** ---------------------------------------------------------------------- ***

Version 1.91ß   MOD loader bug fix                      February 5th, 1993

        - A bug in the module loader, caused infinite loops if trying
          to load a corrupted module. Now DMP prompts wheather or not
          to play the module.

*** ---------------------------------------------------------------------- ***

Version 1.90ß   Support for SB16, PAS+ and PAS16        February 3rd, 1993
                Many bugs fixed
                386 support

        + 386 instruction set is now fully utilized. Which means that DMP
          won't run on a 286 anymore.
        + DMP is now the only module player capable of playing modules
          with 16-bit accuracy. On a SB16 or PAS16 DMP uses a new mixing
          routine that calculates at 16 bits. This gives you a lot clearer
          sound. Also a new mode, Quality mode, is introduced for 8-bit
          cards.
        + DMP is now a lot faster...
        - Numerous bugs were fixed. Can't remember what bugs, though. :-)
        - Support for DACs is removed, because of non-functionality.
        - No more blue backgrounds after exiting (this wasn't a bug, but
          some people didn't like it...)
        ! Special thanks to Pirkka Palosaari for lending his SB16 ASP.

*** ---------------------------------------------------------------------- ***

Version 1.41    DAC support                             December 2nd, 1992

        + Added support for general DACs. Try port value 378 (LPT1)
          If you want to have fun, use port values 3C9,3C0,3C2,61
          (BTW, it took about two hours to add support for DACs... :-)

*** ---------------------------------------------------------------------- ***

Version 1.4     8-channel support                       December 2nd, 1992

        + StarTrekker 8-channel MODs are now supported. If you have
          information about other 8+ channel formats, please send it to me.
        + Some internal changes to ease the way to Covox support in upcoming
          versions...

*** ---------------------------------------------------------------------- ***

Version 1.35    New features                            November 26th, 1992

Version 1.33    Bug fixes                               November 16th, 1992

        - Fixed the fine tune. Old versions played worse than versions
          without fine tune! Remember to reconvert AMF modules with invalid
          fine tunes.
        - Also fixed a bug in portamento command.

*** ---------------------------------------------------------------------- ***

Version 1.32    Faster!                                 November 15th, 1992
                New feature

        + DMP is now faster than ever... just believe me!
        + I've added "the-most-wanted-feature": pattern jump!!!
          Just press B to break to next pattern...
        - I might have fixed some bugs too, don't know for sure though....

*** ---------------------------------------------------------------------- ***

Version 1.31    Bug fixes                               November 2nd, 1992

        - Fixed a bug in AMF converter/loader. DELETE YOUR OLD AMF FILES!!!
        - Some incompatibles in MOD loader fixed.

*** ---------------------------------------------------------------------- ***

Version 1.3     Enhancements                            October 21st, 1992
                Bug fix
                New file format AMF

        + Support for more octaves (0-4) in MODs, because some PC MOD-editors
          (notably ModEd) support these octaves.
        + Now DMP also loads StarTrecker modules
        + DMP now supports AMF modules and includes a program to convert
          STM or MOD formats into AMF.
        * You can reach me through the Internet! Address is:
          c142092@cc.tut.fi
        - Fixed a memory trashing bug

*** ---------------------------------------------------------------------- ***

Version 1.24    Bug fixes                               October 14th, 1992

        - There was a killer bug that prevented SB Pro mode from functioning
          correctly. Now SB Pro owners can find a big improvement in sound
          quality!

*** ---------------------------------------------------------------------- ***

Version 1.23    New features                            October 4th, 1992

        + The playing order of modules can now be scrambled with commandline
          option '/O'.

*** ---------------------------------------------------------------------- ***

Version 1.22    Bug fix                                 October 3rd, 1992

        - Now DMP shows the real sample rate which may differ from
          what user required, but only a little :-)

*** ---------------------------------------------------------------------- ***

Version 1.21    Bug fix                                 September 29th, 1992

        - A bug in tempo command made some modules play REAL SLOW!
          I hope I have now fixed it.
        + I forgot to change the version number in 1.2 :-)

*** ---------------------------------------------------------------------- ***

Version 1.2     New player for DesqView                 September 28th, 1992

        + A player especially designed for DesqView is now included.
          Its name is DMPMT (DMP for MultiTaskers)
        - There was a bug in the DMA routine.. Only in the 1.12 version. Fixed

*** ---------------------------------------------------------------------- ***

Version 1.12    Internal Changes                        September 28th, 1992
                Bugfixes

        + All sound output handling goes through SDI now,
          (SDI = Sound Device Interface) which allows me to add support
          for new sound cards easily by writing a new SDI!!
        - There was a killer bug in the buffer calculation routine, but
          it only occured under very specific conditions. Finally fixed!

        - a bug in the volume table caused cracks in voice. Corrected.
