ThumbJam is a powerful musical performance experience. 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. ---====--- 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.

A music sequencer reimagined with multiple playheads. "How Bach would have made a sequencer." (Create Digital Music) "A musical feat." (Creator's Project) "A new approach to sequencing." (XLR8R) "A next generation music sequencer." (Ask Audio) Fugue Machine Classic is a tool inspired by composition techniques used in Baroque music and Serialism — e.g. Bach’s canons and fugues, and Schoenberg’s twelve-tone technique. The idea was to design a tool to manipulate a melody’s speed, direction, and pitch, as well as play multiple variations of the melody simultaneously. As it turned out, the best implementation for this was to reimagine one of the most fundamental building blocks of all music sequencers: the piano roll. Fugue Machine Classic is the world’s first multi-playhead piano roll. Create a music sequence and play it back with up to four playheads at once — each at various speeds, directions, pitches, and more. Watch the playheads dance, and hear the complex patterns that emerge. It’s mesmerizing. Fugue Machine Classic supports iPhone, iPad, MIDI, AUv3 MIDI, Ableton Link, Audiobus, Audiobus 3 MIDI, and Inter-App Audio. Thanks to the AUv3 standard, you can run multiple instances of Fugue Machine Classic on a single device when hosted in an AUv3 MIDI host app — like AUM, Logic Pro for iPad, Loopy Pro, and Cubasis.
