ok i only tried this with short bass sounds, so not shure how good will work with longer samples. this is how i did it really fast.

make a good synth sound with oscilator pad + enveloper.

now resample all 16 notes to 1 pad. (or the ones you want)
make shure you leave a bit of space between.

now load it into chop, the chop will detect the spaces and chop your notes.

WOOOHOOO. i doubt I invented this but, for once , something is quick and easy. and the synth sounds are awesome.
