Features/improvements from earlier firmware to 1.02: (Source)
Fixed Mix UnCompare bug where when going out of compare in Mix mode all
voices playing should be stopped, but they weren't
Changed Program and Mix Channel RANGE when using keyboard note
presses to set the range so that the Global Keyboard Transpose is taken into account.
Changed software so that its aftertouch would work with both REV C and REV E boards.
This change resulted in a new source file PANEL7.SRC where the black aftertouched
value is forced to the value H'FFFF.
