The use of samples or digitally recorded audio in modular is more of an adjunct than a method for sample playback. You'd have less expense and more success using something like an Akai MPC Live MkII. It will allow for you to load libraries of sounds as well as interface with the modular synthesis world.

That looks like an awesome machine, but seems to be more beat oriented? Doesn’t look like it has the exact tools I’m looking for, although would probably be great for sequencing modular etc.
