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.

A few bugs on new version

I have detected a few bugs on this new version...

* Some instruments (like MegaSaw) keep a sustained note when not playing at all, of course the sustain switch is off.

* When going to the midi/wifi options and changing them then going back to the main screen, the program closes.

* Haven´t found the midi app yet for pc!
