Hi Laurie
Well the guy told me specifically about problems with
GUITAR2 and CLAVICHORD2 and those relate, I guess, with the touch
response ( initial) ; for what I know, the HARPSICHORD2 doesn't have a
pre-cabled velocity response ( by ear ), and ELECTRIC PIANO relates to
Channel-I with the consequence that M-16 should be affected instead...
this guy told me about M26 itself, that is voice number 6 on Channel-
II....I don't think however that this problem lies in the Voice card
itself : I guess it must be related to the TWS board ( responsible to
detect the velocity value ) or the TRG-1 or TRG-3 boards ( initial
touch waveform generator )....
