While I appreciate the help, that's not really the issue I'm stuck with. I've got my sax recordings and related round robins hooked up exactly how I need them, and I've got a collection of plunger recordings to implement; thing is, I want each possible sax note to be able to trigger any of the various plunger recordings, so I thought about mapping every plunger recording to the entire note range, and using round robin control to switch between them; that way the sampler would pick from a pool of plunger sounds, and a pool of sax recordings, so that you'd rarely ever get the exact same combination twice, and that's where I'm running into my problems
