Misomidix

Genre-Driven MIDI Generator

Pick a genre, a key and a length, and Misomidix gives you usable MIDI for drums, chords, bass, melody, stabs and arp that agree with each other. Generated from music theory, not selected from a clip library, so the output never repeats. The six parts are written in dependency order: the drums publish their kick onsets, the chords publish the harmonic grid, then the bass locks to both and the melody locks to the harmony. That ordering is why the bass stops fighting the kick and the melody stops fighting the chords.

FEATURES

Six Parts, Generated As One

◆Drums, chords, bass, melody, stabs and arp written in dependency order, so the parts agree instead of fighting each other
◆Lock any part you like and re-roll the rest
◆Each part carries its own musical logic (per-genre bass modes, voicing, drum programming), not a shared groove template

Fourteen Genres, As Data

◆Tech House, Deep Tech, House, Deep House, Melodic House, Progressive, Afro, Organic, Bass House, Techno, Minimal, Drum & Bass, Hip Hop and Rock
◆Each genre brings its own progressions, drum programming and part behavior, not a folder of clips

Shape It and Share It

◆Six macros, Complexity, Density, Swing, Humanize, Length and Groove
◆Shareable checksummed pattern codes reproduce an exact result, or refuse a typo rather than load something else
◆A/B/C/D snapshots for specific results, presets for the generative formula

Straight Into Your DAW

◆Drag the piano roll onto the timeline, or export every part as one multi-track MIDI file
◆Drop a .mid on the window to import and re-groove your own material; drums are never scale-quantised
◆Full undo and redo over generation, re-rolls, preset loads, snapshot recalls and imports

HOW TO USE MISOMIDIX

How do I get a bassline that fits my chords?

Lock the chords and re-roll the bass. The bass is written against the harmony and the kick, so every new version still follows the same progression.

How do I go from a sparse intro to a busy drop?

Lower Density for the intro and raise it for the drop, then save each version in the A/B/C/D snapshots and drag them into your arrangement.

How do I re-groove MIDI I already have?

Drop a .mid file on the window to import it and re-groove it. Drums are never forced to a scale, so imported beats keep their hits.
