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.

Rozeta is a suite of MIDI sequencers and controllers that lets you explore a new, freeform approach to sequencing and controlling mobile music apps. The app contains 10 MIDI Audio Units (a totally new feature in iOS11) in a single package, which can be loaded in compatible MIDI AU hosts (AUM, Cubasis 2, ApeMatrix, Sequencism). 1) Rozeta Bassline: a monosequencer based on the popular Troublemaker sequencer. Obviously comes with all the randomization and mutation features. Up to 8 patterns per sequence, with Follow Actions. Transpose using MIDI. 2) Rozeta Rhythm: a euclidean drum sequencer with mutations per instrument and polyrhythms. Comes with configurable key mappings for many popular drum apps. 3) Rozeta X0X: classic TR-styles step sequencer for drum machines. Supports triplets, polyrhythms and mutations per channel. Optionally emulates the exact timing jitter pattern of the legendary TR-808 4) Rozeta LFO: a triple MIDI LFO generator lets you modulate CC parameters of your MIDI instruments. Apply amplitude modulation to each wave for more organic behavior. Optionally syncs to tempo. 5) Rozeta XY: a double XY Controller Pad for generating 4 simultaneous configurable CC controller streams per instance. Also features MOD wheel and PitchBend sliders. 6) Rozeta Arpeggio: adds a MIDI arpeggiator to any of your synths. Offers latch mode, shuffle and automatic tempo synchronization. Turn any incoming MIDI stream into an arpeggio on the fly. 7) Rozeta Particles: MIDI particle generator - generates a cloud of MIDI notes that create pseudo-random patterns when bounding off the walls. 8) Rozeta Cells: Polyphonic Step Recorder - record and play back polyphonic phrases and patterns. 9) Rozeta Collider: MIDI Hadron Collider - explore semi-repeating generative patterns and melodies. 10) Rozeta Scaler (NEW): MIDI Scale Quantizer and Transposer - tune incoming MIDI to a different scale, never play out of tune again. Notes: - these plugins do not run as a standalone app and require a compatible host to work - MIDI is not sound. To make sound you'll have to feed the MIDI into a synthesizer or instrument app. Bring your own synths!
