Not to be cocky;)

One should not expect miracles, because the app has to make do with the hardware you have.
I'm playing against myself guitar. A track with a solo, a track with chords, one with vocals. Man can track and synchronize edit. The quality is not enough NATURALLY to record a CD, but in any case retain his ideas. Oh, have an Asus Transformer. From my 10 star and a strong buy recommendation!
