do you already have an audio interface?

do you already have midi i/o from computer?

I have the Focusrite 8i6. As far as MIDI i/o, it runs through the Focusrite...I have an Ableton Push 2 and also a Novation Launchkey 49 (sometimes I just have to have the keys vs pads :) and they are USB connected to my PC. I think it would be interesting to be able to take sounds from a track in Ableton (for example, i have an iPad with some cool/different synths (Animoog and Sound Prism to name just a couple)...and run them through various modules in my rack and then back into another track in Ableton...would that be accomplished with some sort of 'sampler' module?
