ThumbJam is a powerful musical performance experience for iPhone, iPad and iPod Touch. You get over 40 high-quality real instruments multi-sampled exclusively for this app. Hundreds of included scales allow you to effortlessly play in any style from rock to classical, whether you are a musical novice or a seasoned professional.

Version 2.4.2 is the latest version

Jordan Rudess, the world-renowned keyboardist for Dream Theater says:
"ThumbJam stands at the very top of the overcrowded music app world. The sounds included absolutely rival those found in pro instruments and making music on the app is a total joy. The only problem I have with this app is that I did not make it myself! Luckily, I'm able to work with the developer and offer a few good feature ideas as well as some choice sounds from my personal collection!"

Even if you've only played air guitar, ThumbJam lets you sound like a pro. Pick an instrument and jam -- with all the scales to choose from you'll never hit a wrong note. The high quality instrument samples will make you sound like you just skipped years of music lessons.

For the performing musician, this app is awesome for soloing on an instrument you didn't bring along. Play in any key, any style -- go from a string ensemble to a wailing guitar. ThumbJam was developed and tested by musicians to feel and sound like a real instrument.

ThumbJam makes use of tilt and shake to add vibrato, tremolo, note bends, and volume swells for more realistic and expressive results. It supports up to eleven (or five on iPhone) simultaneous touches and up to 24 voice polyphony per instrument. You can even load more instruments simultaneously and split the screen to play them. Delay and lush stereo reverb add depth to the sound. Put on your headphones or plug in to your home stereo and prepare to be blown away.

Build your own loops from the ground up or import your favorites and jam from there. Layer as many loops as you want, with different instruments for each, as well as live microphone recordings using the built-in mic or external ones such as IK Multimedia's iRig Mic or iRig HD. Export your loops as audio files or Ardour and Mixbus sessions.

Audiobus support from the start. Now you can play or record audio to and from ThumbJam directly with other Audiobus-compatible apps! See for more information.

Copy and Paste your loops or samples between other apps that support Sonoma Wireworks AudioCopy/AudioPaste or Intua's pasteboard. Or export or import audio directly using Open In other applications.

Want to jam with your friends? ThumbJam lets you broadcast tempo, key, and scale to other nearby devices via Bluetooth so you can play together live. Even better, you can use it as a MIDI or OSC controller over Wifi to control software instruments on your computer! CoreMidi, Akai Synthstation25 and Line6 MidiMobilizer support is coming soon.

The app includes a huge variety of scales, from western to eastern. Save your favorites for quick access. You can even import new scales in the Scala format for complete flexibility.

To expand the power of ThumbJam, new instruments are available for download, including Mellotron, more synths, banjo, harp, and more. You can also record your own samples using a built-in or attached microphone and play them instantly. Create your own presets with different settings, scales and keys based on the existing instruments.

To hold your iPad on stage, check out IK Multimedia's iKlip which puts ThumbJam into a great playing position, freeing up both your hands for expression.
