I am hoping future versions of my favorite iPhone app Synthpond will let me use my own samples. You can do so today by incorporating some intense geekery via PD (Pure Data) or Max. If you’re interested in learning about PD check out a great article by Jim Alkin over at O’Reilly Digital Media called “Make Your Own Music Software with Pure Data”: click here. There is also a good Wikipedia page for PD: click here.
“I’m using the synthpond PD patch to controle the FPC in FL studio. The sound generator nodes don’t have samples mapped (except for the hi-hats). Only the reactor nodes are mapped to a sample. that way it’s a bit easier to “sync” everything.” – isnie zot
