And of course there's the Virus TI Atomizer, which granularizes any streaming audio-in, the timings of which depend on the keys pressed on the Virus keyboard:
You may wish to disable Virus MIDI out to the MPC when using Atomizer in this case to avoid triggering conflicts with the MPC. Atomizer isn't usually used for triggering external samples, as such, it's more for processing streaming audio via the audio-in.
^ oops, edited Youtube video syntax, should work now

A ribbon-controller or XY-Pad might be nice, too, please! Thanks!
