Q: I want to use them in songs for things as like a keyboard patch for phrases that keep going in (mostly) one direction. But it's hard to figure out how to do it? All the stuff I find is about continuous glissandos, which is cool and all, but not what I'm looking for...
A: you could just record what you need, and then double it in octaves and fade the volume as needed. would take a little bit of busy work, but it will get the job done
