So you could load a guitar sample, and make it play with the amplitude/pattern of a 4x4 drum loop for example
Or load one drum loop and play it with the pattern of another
Or load a vocal line, and make it play like an synthy arp loop
Would involve analysing both samples in segments I guess, set by user possibly, for example 16ths
Not sure if it's possible, just an idea for ya
Edit: I guess you'd call it a sample spawned pattern gate (maybe) ?
