Lately, it seems TC-Helicon have been devoting quite a bit of attention to promoting Voice Looping (their VoiceLive Touch product, for instance). Now, they've come out with VoiceJam for the iPhone/iPad: http://www.tc-helicon.com/products/voicejam/ Haven't tried it yet (my credit card and the iTunes store are fighting with each other again). But it seems pretty spiffy for only $1.99. --m.
