Full Specifications

What's new in version 1.3
Version 1.3 fixes the lack of sound issue for iPod touch devices. It also adds native iPad support! This is just the beginning for the iPad version. Look forward to more updates that further take advantage of iPad-specific features. PLEASE update your reviews and ratings to reflect the capabilities of this version! Again, we are very sorry for the extended delay on this fix. Also if you have questions or suggestions, please ask on the forums at or via email at We cannot provide feedback on iTunes App Store reviews, which is frustrating when we have the answers you need. ----- Features from 1.2.x still worth mentioning: Includes support for fast switching and background audio operation (if loops are playing) under iOS4. === Metronome and Looping === - Metronome added with a selection of sounds - Set tempo directly or tapping - Specify number of beats per bar - A 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 - Added support for recording loops with the microphone (internal on iphones, and/or externally connected for all devices) === 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. === Other Updates === - New Viola instrument to round out your string quartet - Split-screen ability increases playable note space while also allowing for independent setting of key and note range per side. Toggle the split-screen feature from the key change popup in the key controls sidebar. - Added inverted tilt option for pitch control - In-app news added to notify users of new available instruments, loops, or other tips - Sonoma Wireworks AudioCopy/Paste 1.1 support, allows for copying and pasting multiple simultaneous files.
