Build on the idea of instability, this MPE compatible sequencer creates constantly changing patterns of notes with modulated note parameters. Each time the sequence reaches the end, the sequence length itself grows or shrinks, within predefined limitations, creating unpredictable rhythmic patterns. The changes in length can also be mapped to velocity level, note length, and MPE slide and pressure parameter values.The device consists of 8 note sequencers with individual controls for grow mode, step size, minimum and maximum sequence length, growth amount, hold, and probability. It also includes the option to freeze specific sequences to prevent changes. Global controls allow us to set swing amount to loosen up midi timing and note pitches can be set using a scale selection.
