 Yeah I just worked on a symphonizer the other day and it's the
earliest one I think Crumar made isn't it?  Older looking design than
the stringman etc.  Anyway I think it uses a MK50242 TOS..I can't
recall. Multiman has the MK50240 which is more common.   I should have
written more info on it while I had it here.  I seem to recall the
SAJ110 dividers but those would generally be bad if you were missing
sub-octaves.  If it's all the notes of a type them most likely the Top
octave synth chip (TOS) or discrete oscillators in units that have 1
for each note (12).  Like combo organs or the early Roland EP10 piano
etc.  But all the crumars used TOS chips I believe.  -bob
