This is a new approach for a sequencer (not a step sequencer at all).
The idea is to generate rhythms from one rhythm "seed" (simple rhythmic pattern), then use mutated copies of this seed to create something more interesting, all this in realtime using knobs and buttons.
This is really a generative music device, that builds a real time MIDI loop based on an underlying theory.
On this video, the first switch selects the GLOBAL settings: step duration (quarter, 8th etc.), swing factor, tempo. There are only 3 instances (i.e. mutated copies of the same seed), selected by the switches 1, 2 and 3.
Each instance can have its Phase, Stretch, MIDI note, velocity and MIDI channel set individually. Here I have preset the MIDI channels before: instance 1 on channel 1 (the microKorg) and instances 2 and 3 on channel 2 (the MPC with a 808 drum kit).
The goal is to build a simple beat by only adjusting the parameters.
