From an Empty Session to a Full Loop with Misomidix

Misomidix is a MIDI generator for Mac and Windows that writes a whole loop for you: drums, chords, bass, melody, stabs and arp, written together so the parts fit. Pick a genre, a key and a length, and you have editable MIDI to start a track on in a few clicks.

What problem does Misomidix solve?

Every producer knows the empty session. You can hear the groove in your head, but the timeline is blank, and getting there means programming drums, finding a progression, then writing a bassline that doesn't step on the kick. By the time the parts work together, the idea you started with has often gone cold.

Pulling parts from different places doesn't really solve it either. A drum loop, a chord clip and a bass clip that were never written for each other tend to clash: the bass lands against the kick, or the top line drifts off the chords, and you spend the session fixing collisions instead of writing.

How does Misomidix keep the parts together?

It writes them in an order where each part can listen to the ones before it. The drums go first and mark where the kick lands. The chords set the harmony. The bass is then written against both, so it follows the progression and sits with the kick, and the melody is written over the harmony instead of on top of it. Stabs and arp take the same chord tones into short hits and running patterns.

Nothing is pulled from a clip library. Each genre is described as rules (its progressions, its drum programming, how its bass and melody behave), and every note is generated from those rules.

What does a Misomidix session look like?

1. Load it. Put Misomidix on a MIDI track ahead of an instrument, or open the Standalone app.
2. Pick a genre, a key and a length. Fourteen genres, from Tech House and Deep Tech to Afro, Techno, Drum & Bass, Hip Hop and Rock.
3. Shape it with six macros: Complexity, Density, Swing, Humanize, Length and Groove.
4. Keep what works. Lock the parts you like and re-roll the rest until the loop sits right.
5. Save the good ones. Store results in the A/B/C/D snapshots, or copy a pattern code to get an exact result back later or share it. A mistyped code is refused instead of loading something else.
6. Take it into your DAW. Drag the piano roll onto the timeline, or export every part as one multi-track MIDI file, then edit it like any MIDI you wrote yourself.

Already have a part you like? 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. Undo and redo cover every step: generations, re-rolls, presets, snapshots and imports.

Do you need all six parts?

If you only need one part, each micro edition runs the same engine and writes just that part: MisomidixDrums, MisomidixChords, MisomidixBass, MisomidixMelody, MisomidixStabs and MisomidixArp. If you want more than one part, the full Misomidix writes all six together. It's also in the MIDI Bundle.
