What is Misomidix?

Misomidix is a MIDI generator for Mac and Windows. Pick a genre, a key and a length, and it writes drums, chords, bass, melody, stabs and arp that fit together. It makes no sound on its own: put it on a MIDI track ahead of an instrument, or drag its MIDI onto your timeline.

Nothing comes from a clip library. Each of its 14 genres is described as rules, and every note is generated from them, in an order where each part can follow the last: the drums mark where the kick lands, the chords set the harmony, and the bass, melody, stabs and arp are written against both. That is why the bass doesn't fight the kick and the melody doesn't fight the chords.

How does generative MIDI work?

A generative MIDI tool writes notes from rules rather than playing back a clip library. Misomidix describes each genre as a set of musical constraints: where the kick lands, how chords are voiced, which bass modes are available, and how the melody resolves against the harmony. Every note is produced fresh each time you press Generate.

The parts are written in dependency order. The drums go first and publish where the kick falls. The chords set the harmony. The bass, melody, stabs and arp are then written against both, which is why they agree instead of fighting each other. The same order runs whether you generate all six parts at once or re-roll a single one.

Quick start

Get a result with Misomidix in under a minute.

  1. Insert it. Put Misomidix on a MIDI track ahead of an instrument, or open the Standalone app.
  2. Pick the style. Choose a genre, a key, a scale and a length.
  3. Generate. Press Generate for a loop of all six parts.
  4. Refine. Lock the parts you like. Re-roll the ones you don’t, or adjust Density and Complexity.
  5. Export. Drag parts to your DAW with Drag to DAW, or press Export MIDI for a multi-track file.

The interface

The Misomidix interface with numbered markers on every control: the transport and mode toggles, the genre, key, scale, length and progression menus, presets, snapshots, the pattern code, the part buttons and locks, nine knobs, the generate and export buttons, Fold and the piano roll.
Tap a number to jump to that control. Drag the bottom-right corner of the plugin window to resize it.

Controls

Top bar

Top bar section of Misomidix
  • 1
    Fire Head: click the flame logo to open the About panel: what the plugin is, who made it, its version and the trademark notices. Click anywhere in the panel to close it.
  • 2
    BPM: the tempo used when no host provides one, as in the Standalone app. In a DAW, the host's tempo is followed automatically.60 to 200 BPM, default 124
  • 3
    Play: the plugin's own transport, used whenever the host isn't driving playback. It is on by default.
  • 4
    Host Sync: follows your DAW's tempo and transport. Switch it off to audition with the plugin's own clock while the DAW is stopped.
  • 5
    MIDI Out: the output gate: when it's on, the generated notes leave the plugin. If it's off, Misomidix still runs but nothing reaches your instrument. It is on by default.
  • 6
    Build: regenerates the loop as an energy build toward the drop: the drums become a ratcheting roll and the pitched parts a filter riser. It works best on 8 or 16 bars and overrides Arrange.
    Tip Use Build on an 8 or 16-bar loop right before a drop. It overrides Arrange, so the whole loop becomes a ratcheting build.
  • 7
    Preview: plays the pattern through a built-in preview synth, so you can audition it in place. Route the MIDI to your own instrument for the final sound.

What to write

What to write section of Misomidix
  • 8
    Genre: the style the parts are written in. Each genre brings its own progressions, drum programming and part behavior.Tech House, Deep Tech, House, Deep House, Melodic House, Progressive House, Afro House, Organic House, Bass House, Techno, Minimal, Drum & Bass, Hip Hop / Rap, Rock
    Tip Each genre is a different set of rules, not a different clip folder. Switching genres changes the drum programming, the bass modes, the voicing and the phrasing.
  • 9
    Key: the key of the loop.
  • 10
    Scale: the scale the pitched parts use.
  • 11
    Loop length: how many bars the loop is.
  • 12
    Progression: picks a specific chord progression from the genre's pool. Any progression lets the genre choose by weight.

Presets, snapshots and codes

Presets, snapshots and codes section of Misomidix
  • 13
    Presets: presets store the generative formula, the settings that produce a kind of result, and are saved to disk by name.
  • 14
    Save / Load: Save stores the current settings as a user preset; Load opens a preset file from anywhere on disk.
  • 15
    Clear: empties all four snapshot slots. The pattern you're on is untouched.
  • 16
    Snapshots: four numbered slots for this session. Click + to keep the pattern you're on (it becomes the next number), and click a number to come back to it. Alt-click a slot to store over it. Snapshots are saved with your project.
    Tip Store an intro version in slot 1 and a drop version in slot 2, then drag each one into your timeline for an instant arrangement.
  • 17
    Undo / Redo: undo and redo cover generating, re-rolls, preset loads, snapshot recalls and imports.
  • 18
    Pattern code: the current pattern as a shareable code. Paste a code in and press Apply or Enter to get that exact pattern back: genre, key, scale, length, progression, all six macros and the seed.
  • 19
    Apply / Copy: Apply loads the code in the box; Copy puts this pattern's code on your clipboard. Codes carry a checksum, so a mistyped code is refused instead of loading something else.

Parts

Parts section of Misomidix
  • 20
    Part buttons: Drums, Chords, Bass, Melody, Stabs and Arp. Click a part to view and generate it; click it again to switch it off. Each part carries its own musical logic, such as per-genre bass modes, chord voicing and drum programming.
    Tip Lock the chords first, then re-roll the bass and melody against them. The locked chords also freeze the progression.
  • 21
    Lock: the circle beside each part. A locked part survives a re-roll, and locking the chords also freezes the progression.
    Tip A locked part survives both Generate and Re-roll. Lock everything except the one part you want to change.

Macros and shaping

Macros and shaping section of Misomidix
  • 22
    Complexity: how complex the generated parts are.0 to 100%, default 50%
  • 23
    Density: how many notes there are. Low for a sparse intro, high for a busy drop.0 to 100%, default 60%
    Tip Lower Density for a sparse intro, raise it for a busy drop. Each version can go into a snapshot slot for quick comparison.
  • 24
    Swing: the swing of the timing.0 to 100%, default 50%
  • 25
    Humanize: adds a human feel to the timing and playing.0 to 100%, default 30%
  • 26
    Length: note length: below 100% shortens notes toward staccato, above it lengthens them toward legato. Notes still never collide.10% to 200%, default 100%
  • 27
    Groove: leans the whole timing ahead of the beat (Rush) or behind it (Drag).Rush 100% to Drag 100%, default Straight
  • 28
    Arrange: shapes the loop into intro, build and drop sections. Most audible on 8 or 16 bars.0 to 100%, default 0%
    Tip Arrange shapes the loop into intro, build and drop sections. Pair it with an 8 or 16-bar length for the most audible result.
  • 29
    Drift: a wandering micro-timing: unlike Groove, which leans evenly, Drift moves the timing around.Off to 100%, default off
  • 30
    Gate: shown for the Melody part: shortens the melody toward a pluck without touching the other parts. 100% leaves the genre's own phrasing untouched.0 to 100%, default 100%

Generate and export

Generate and export section of Misomidix
  • 31
    Generate: generates a new pattern. Locked parts are kept.
  • 32
    Re-roll: re-rolls only the part on screen. Everything else stays put.
  • 33

    Tip Drag from this handle to place one part, or use Drag All to take every enabled part at once. The MIDI carries the tempo from the host.
  • 35
    Drag All: drag from this handle to take every enabled part at once, as separate tracks in one file.
  • 36
    Fold: shows only the pitches the part actually uses, so the piano roll stays compact.
  • 37
    Piano roll: shows the notes of the part on screen. You can also drag it onto your timeline.

Meters and displays

  • 37
    Piano roll: shows the notes, with the bar numbers along the top and the chord names above each bar.
  • MIDI files on the window: 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.

How does the sound flow through Misomidix?

Misomidix writes MIDI, not audio. The parts are written in this order, each one following the ones before it.

What does a typical arrangement look like?

A typical electronic track follows a shape like this. Use Arrange and Build to match these sections, and store each one in a snapshot slot.

Bar counts are a common starting point. Your track's genre and energy will guide the final lengths.

Circle of fifths

Adjacent keys on the circle share the most notes, so changing the Key one step around the circle keeps the transition between loops smooth. The formulas show the interval pattern for each of Misomidix’s Scale options.

W = whole step (two semitones). H = half step (one semitone). W+H = three semitones. F♯ at the bottom of the circle is the same pitch as G♭.

The arrows start from C major. One step clockwise to G adds a sharp, one step counterclockwise to F adds a flat, and each keeps six of C major’s seven notes. The inner arrow goes to A minor, the relative minor, which uses the same seven notes. In Misomidix, set Key to G or F for a one-step move, or Key to A with Scale on Minor for the relative move.

Swing grid

Swing delays every off-beat note in the generated pattern. The amount depends on the genre.

Shown for House (ratio 0.53–0.62). Lo-fi and UK Garage swing more; Techno and Trance stay nearly straight. Even at 0% the genre may add a slight lean.

Tip Combine Swing with Humanize and Groove for a feel that shifts without sounding mechanical.

Which drum parts play at each Density?

In the drum part, Density also decides which parts play at all. The full groove sits on the top row; as Density falls, parts drop out until only the core beat is left for a stripped intro.

House genre. Kick, clap and closed hat play at any Density; the open hat comes in at 25%, the shaker at 50%, the perc at 60% and the ride at 80%. Each genre sets its own parts and thresholds, so other genres thin out differently.

How do I build a loop with Misomidix?

  1. Load it. Put Misomidix on a MIDI track ahead of an instrument, or open the Standalone app.
  2. Set it up. Pick a genre, a key, a scale and a length.
  3. Generate. Press Generate for a loop of all six parts.
  4. Keep what works. Lock the parts you like with the circle beside each one. Select a part you want to change and press Re-roll, or press Generate for new versions of everything that isn't locked.
  5. Shape it. Use the macros: lower Density for an intro, raise it for a drop. Keep each version in a snapshot slot with +.
  6. Take it out. Drag the part on screen with Drag to DAW, every part with Drag All, or press Export MIDI for one multi-track file. Copy the pattern code to get the result back later.

How do I turn one loop into a full arrangement with Misomidix?

  1. Generate a full loop. Pick a genre, key and length (8 or 16 bars works best), then press Generate.
  2. Save the drop version. Adjust Density and Complexity until the loop feels like a peak-time drop, then press + to store it in snapshot slot 1.
  3. Strip it for the intro. Lower Density for a sparse version, switch off the parts you don't need, and store it in slot 2.
  4. Make the build. Switch Build on. It overrides Arrange and turns the loop into a ratcheting build. Store it in slot 3.
  5. Drag each section into your DAW. Recall each snapshot in turn and drag it onto the timeline with Drag All. Copy the pattern codes so you can get back to any of them.

What about Misomidix Raw?

Misomidix Raw, the one-knob version, with its BUILD knob and NEW button.

Misomidix Raw is the one-knob version. Its BUILD knob takes a four-bar loop of drums, chords, bass, melody and stabs from a stripped intro to a peak-time groove, and NEW rolls a different loop in a different genre and key. Need only one part? The six micro editions each write one part on the same engine: MisomidixDrums, Chords, Bass, Melody, Stabs and Arp. Its own manual: Misomidix Raw manual.

Frequently Asked Questions

Keep it in one of the four snapshot slots, save the settings as a preset, or copy its pattern code. Pasting the code back in with Apply gives you that exact result.

A locked part stays exactly as it is when you generate or re-roll, so you can keep the chords you like and try new basslines against them. Locking the chords also freezes the progression.

In some hosts the CLAP version shows up under Audio FX as well as Instruments. Either one works.

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

Misomidix only writes MIDI, so route it to an instrument, or switch on Preview to audition it. Then check that Play and MIDI Out are on; both are on by default.
