IK Multimedia has released version 2.1 of Amplitube, which is now compatible with Intel-Macs.
In addition to Intel-Mac compatibility, there are several enhancements that have been implemented, such as Pro Tools 7 native support and improved CPU efficiency, plus the copy protection has reverted back to Challenge/Response (i.e. the dongle protection has been removed).
Also available in the update is the standalone version of AmpliTube 2.1 which includes SpeedTrainer, an audio player with pitch and speed controls that make it ideal for learning any of your favorite songs. Slow tempos of guitar solos without changing the pitch to track any riff. SpeedTrainer allows you to drag any WAV or MP3 from your hard disk (even iTunes files) and set loop points easily for playing over and tracking your preferred song. Also, an included metronome (set by BPM or Tap) is useful for the studying and practicing guitarist or bassist.
A demo version of AmpliTube 2.1 is also now available. It is fully functional for a grace period of 10 days.
