Is there an explanation for... The root does not have to be between the low and high values. The root specifies what note was sampled at the specified sample rate. When the low and high values are the same then that sample will only play on one note of the keyboard. For the above example the GUS will play the 870.183 Hz sample back at the new frequency of 1244.507. That changes a sampled Flat A5 (almost 880Hz) into a D#6. The Scale Freq & Factor are used to change the tuning of the whole sample but I do not know how they are applied. You can see what the do by playing with the patch editor.
