Is it possible, with any digital audio players, to record voice and listen to music simultaneously?
Furthermore, is it possible to turn a portable mp3 player into an effects unit?
Even better-- one that could load VST chains?
Today I've been experiencing the world with laptop in backpack, hooked up to (noise canceling) headphones and a (stereo) microphone, processing everything I hear with various effects through Ableton. It's the greatest, most amazing, most hilarious idea I've ever had.

I would love to be able to do this without carrying around cumbersome equipment.
Any suggestions?
(o_o try it...
