  • Load your favorite songs as MIDI files from the Internet, and watch at the virtual keyboard how to play them.
  • Unlimited amount of tracks.
  • Unlimited recording and playback length.
  • Open MIDI (.mid) files directly from other apps (i.e. from Safari, Mail).
  • Download or upload MIDI files with iTunes.
  • Metronome.

  • Use the "BPM" dial to record new or to overwrite existing tempo changes on the master track.

Appropriate polyphony is automatically detected and selected for your specific device model by the app for you. If desired however, you can override the polyphony setting manually in the app's settings screen. For example to save CPU head room for other apps running in the background.

Please Note: This app requires quite some hardware resources from the device. In case there are problems with this app, please close other apps running in the background.


The marked younger device models actually support a much higher polyphony than listed above, due to performance reasons however the polyphony is throttled to 140 stereo voices by default. You may override this and increase the polyphony on such device models by accessing the app's settings screen.
