this would be a cool free update for all live 8 users
A device that could be placed on the master channel or whever needed to analyze the audio (kick drum or even vocals) and tell you what it's tuned and also be able to export a midi file of the looped selected audio

there are some softwares that do this, i think it would take up way too much memory to do this with live. I have never been able to get accurate midi messages out of audio files, it's kind of like a guitar to midi processor, it's never 100% correct.
