Play your beats.
No DAW required.
Plug in a drum machine or any synth with drum sounds, and Miditrax turns it into a generative, clock-synced beat sequencer you actually play, with live, mappable fills.
macOS 12+ · Windows 10+
Miditrax sequencing an RD-9 over MIDI at 90 BPM. No DAW in sight.
An instrument, not a studio.
A DAW is built to arrange. It wants a project, armed tracks, a mouse, and a screen. That’s overkill when all you want is a groove out of the gear on your desk.
Open Miditrax and you’re already making beats. Hit a fill with a button, not a menu. It’s the fast lane back to the part of beat-making that’s actually fun.
Your gear, finally sequenced properly.
Instant
Plug in. Go. No setup, no boot time, no track arming. Miditrax is making beats the second your gear is connected.
Your drum machine’s missing sequencer
Your 808 gives you one lane of sixteen steps. Miditrax hands that same drum machine a full, generative sequencing surface with vastly more pattern, variation and depth than the front panel ever would.
Live
Miditrax has clock. Sync your gear, then perform and play your drum machine like the instrument it always wanted to be. Map Miditrax buttons to a MIDI controller (think Stream Deck) for hands-on live performance.
The full pattern, live. Every lane, sixteen steps, swing and fills.
A live sequencing surface.
See your entire pattern in one view. Sculpt while it plays. Every lane does far more than on-or-off. Add variations to make any beat perfect or even better, imperfect with micro timing, swing and chance.

Beats on tap. Then make them yours.
Start from a growing library of beats, or a blank grid. Stuck? Pick a style and a density, hit Generate, and keep rolling the dice until one clicks. Then push it. Dial in Variation, Cymbals and Percussion, and add Fills on demand.
Eight pattern slots per beat let you build a verse, chorus, bridge and outro that all stay in the pocket. And it all stays live. Nudge a slider, fire a fill, queue the next pattern at the bar. The groove never stops.
It speaks in kick and snare.
Pick a map (General MIDI, a hardware drum machine, or a plugin like Addictive Drums or Studio Drummer) and the grid lays itself out for the kit you’re actually playing. Your beat thinks in Kick, Snare and Hat, not CC 36, so the same groove jumps from your 909 to a VST and still sounds like itself.
Built-in maps for GM, XO, Addictive Drums, Studio Drummer and more.
Built to be played.
Up to 8 patterns per beat
A beat preset holds up to eight patterns (A–H), more than enough for an intro, verse, chorus, bridge and outro on stage. Each pattern has its own optional Fill, and Chance (probability) variation keeps the groove from ever feeling robotic.
Humanize the whole beat, or one lane
Swing, accents and micro-timing, applied globally across the pattern, or to a single lane (think hi-hats on swing).
Play it live
Map on-screen controls to an external MIDI controller (a Stream Deck, say) and perform. Switch patterns and fire fills on the fly, all at the press of a button.
Preset Library & User PresetsPro
A growing library of beats across hip hop, house, breakbeat, disco and more. Load one and play, or use it as a starting point, then save your own user presets with locked-in BPM and recall them live. Saving presets is a Pro feature.
MIDI import & exportPro
Save a pattern to a MIDI file or drag it straight into your DAW. It works both ways. Drop a MIDI file onto the grid and it’s ready to play.
Kit maps for your gear
