As  a  progammer  working with MIDI, I often have to refer to the MIDI
Spec document to find out what bytes are used for the many commands so
I can put them in my programs. The commands are in binary format and a
calculator  is  needed  to convert them to decimal. Therefore, I wrote
this small pop-up utility that will terminate and  stay  resident  and
produce a list of MIDI commands at the touch of a key.

Not  every command is included in the pop-up, a few had to be left off
due to space limitations. Also in the language of MIDI, Channel  1  is
specified  by  a data byte of 0000 , Channel 2 by 0001 .... Channel 16
by 1111 (15 decimal or F hexadecimal). Therefore, for any  Channel  N,
the  proper  data  to use to designate that channel is equal to N - 1.
For example, a Note Off command is 128(decimal) + the channel number.
    For Channel  1, note off =  128 + 0
        Channel  2, note off =  128 + 1
        Channel  3, note off =  128 + 2
        ...                           
        Channel 16, note off =  128 + 15
The note and velocity must also be sent after the note off command, of
course.  The  same  numbering system applies to the channels when used
with all of the other commands also.

The active sensing command is optional but once it is sent, the  synth
will expect it to continue to be sent at least every 300 ms. It's best
to  stay away from this since it is just more data to clog up the MIDI
channel.

The Tune Request command is for analog synths that will need  to  tune
their oscillators.

Hitting  the Alt-Left Shift key calls the MIDI POPup to the screen and
escape will remove it. This program should have  no  problem  with any
IBM compatibles but there are NO guarantees.

MIDIhex.com is identical to MIDIpop.com except the numerical values 
are all in hexadecimal. Both programs were created with TSRmaker.
