this is closer to what Redmatica (now Logic) AutoSampler used to do.... you would just play notes (separately by space), it would split by space, detect the root note for each sample, and then make a multisample out of it.

but actually trying to reproduce a real instrument involves legato between notes, handling pitch and timbre changes as you play, etc. So a much harder problem.

Thanks for that info. Familiar with Logic, didnt know that history though.

Thanks
