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.
