ThumbJam v1.2 released

Metronome and Looping Updates

  • Metronome added with a selection of sounds
  • Set tempo directly or tapping
  • Specify number of beats per bar
  • Fixed loop length option lets you specify ahead of time how long of a loop you want to record in bars.
  • More lenient timing when ending loops

MIDI and OSC live output

You can now use ThumbJam as a MIDI or OSC controller over wifi for software instruments or midi sequencers on your computer. Look at the Prefs->Remote Control page to enable these features. For the MIDI output you will need to the DSMIDIWiFi server software on your Mac/Windows/Linux PC found at to receive the MIDI data. For best results connect your device and computer using an ad-hoc wireless network directly between them. See the forums at for more detailed instructions, and for a description of the OSC messages sent.
