Locus vs SuperGrid

Locus is a generative MIDI sequencer that creates evolving melodic motifs and sends them to your favorite synths. Designed for techno, ambient, IDM, and experimental electronic music, it turns a single seed into fresh musical ideas across thirteen generative archetypes, from acid-style grooves and cascading arpeggios to sparse fractals and interlocking pulses. Use Locus as a standalone app or as an AUv3 MIDI effect inside hosts like AUM, Logic, Cubasis, and Drambo. Every generated pattern plays in sync with your host and routes over MIDI to any instrument you choose. GENERATION Press CREATE and Locus composes a new motif from the current archetype, rooted in your chosen key and scale. Each archetype has its own rhythmic and melodic character: Groove, Cascade, Arc, Wander, Call & Answer, Chaos, Pulse, Even Pulse, Sparse Fractal, Interlock, Cluster, Puncture, and Thump. Generation is seed-derived, so the same settings always reproduce the same pattern. EVOLVE Push EVOLVE to generate controlled variations of the current motif. Keep what works, mutate what doesn't. Rhythm and pitch shift in musically coherent ways without losing the pattern's identity. FEEL Shape the musical foundation with Root, Scale, Timing, Steps, Octave range, Swing, Dynamics, and Density. 25 scales keep everything in key. Raise density to fill the grid or thin it out for space. EDIT & SLIDE Engage Pattern Lock to edit the authored pattern directly: rotate, move, and transpose notes, or undo and redo. The SLIDE knob adds per-note slides with 303-style legato, gliding between pitches for classic acid phrasing. Slides even carry across density-thinned notes. SCENES Capture complete musical setups in sixteen scene slots and chain them into full arrangements. Each scene remembers its pattern, archetype, feel settings, and slide amount. STANDALONE & AUV3 Use Locus as a standalone app or as an AUv3 MIDI effect. It runs in AUv3 hosts such as AUM, Logic, Cubasis, and Drambo, following host transport and clock.
