Casio CZ/ VZ/ FZ - Pro Series

thanks for codejose

 there are some doubts..

like why does the for/next loop conrol variable  'i' also get deducted from
the samplesize?

samplesize is never defined
samplebuffer is not dimensioned

other than that i like it ,  i allready have helped a fellow program redisgn
his wave making program , and there are a lot more parameters used to create
a waveform (within his program)

but the set back is , its always a sin wave ,,,,

any method to employ to make a saw ,pulse,square  ,triangle

where do i find this code on c-sound ?
thanks in advance
charles
