IK MultiMedia have released a major new update to their guitar recording and effects application for iPhone, AmpliTube. The new v2 improves the sound quality of gear and cabinets, imports songs from the iTunes Library as backing tracks, and now includes the ability to slow down or speed up imported songs without affecting the pitch in a new feature called SpeedTrainer. However, iPad AmpliTube users are advised to wait for a special, dedicated upgrade for their devices.
