Developer Anthony Saunders has introduced Quantum, a performance MIDI sequencer that’s modeled after old-school step sequencers and designed for ‘noodling’. It is an evolution of his earlier sequencing app, MidiSequencer.
Quantum’s approach is built around the idea of a step being the focus. You can have any length up to 64, but these can be further split into 4 sub-sequences that have their own set of sequencer parameters (like tempo, play direction, transpose etc).
16 general faders are available which allow you to draw, drag, select copy/paste, inc/dec & link together to edit values. These are also MIDI-learnable (midi cc or nrpn) to allow you to use control surfaces or midi controllers.
To aid you with faster control Quantum has loop actions which you can program in to carry out tasks when a sequence loops – e.g. transpose, randomise, start or load another sequence etc.
With up to 24 sequences playing, Quantum introduces a mixer page allowing you to blend midi velocities. Built on the MidiSequencer engine, midi FX, devices & Controllers are now possible per sequence.
Note: Quantum is a MIDI sequencer and does not make sounds on its own.
