NOTES:
1) "Swell Channel" defaults to 1 (0h) - usually the Ahlborn "A" division for key On/Off messages. kk = Note
number 0-127 (00h to 7Fh) where 60 (3Ch) = middle "C". Normal (untransposed) output from key inputs 1-61
= 36-96 (24h - 60h). Transposer may shift this down or up in the range of -24 to +31.
2) "Great Channel" defaults to 2 (1h) - usually the Ahlborn "B" division for key On/Off messages.
3) "Choir Channel" defaults to 3 (2h) - usually the Ahlborn "AUX" division for key On/Off messages.
4) "Pedal Channel" defaults to 4 (3h) - usually the Ahlborn "Pedal" division for key On/Off messages. Normal
(untransposed) output from key inputs 1-32 = 36-67 (24h - 43h). Transposer may shift this down or up in the
range of -24 to +31.
5) Ahlborn modules respond only in the range - kk = 30-99 (1Eh to 63h) for A and B divisions and kk = 30-70
(1Eh to 46h) for the Pedal division.
