PLOF and LPOF are cool ! but you missed the point
SAMP xxyy triggers sample xx at offset yy!
so you could use samples from other instruments in each other- and more than one sample in the same instrument! AFAIK PLOF and LPOF just let you cut up one sample, and each instrument is tied to only using one sample
i think this would be insanely powerful~ a table would become just as valid a place to write (short pieces) music as a phrase, not to mention all the wacky sound design you could do by combining (sequencing) samples at high speed!
the idea came from c64 tracking and the wavetables there... there are no samples, but you can switch between radically different tones as you wish within the wavetable. of course you don't really NEED this in a sample tracker, you can get cool sounds just by using cool samples... but i thought it would expand the creative potential a lot
just an idea anyway
