Windows app

MIDI in.
Anything out.

Plug in a MIDI keyboard or pads. Hit Learn, play a note, and that note becomes a shortcut in a game, OBS, a browser, anywhere. It keeps working while another window is focused.

A piano can play Minecraft. A pad can mute Discord.

Download for Windows See how it works

Click a key to hear it. Watch the list cycle a note, a chord, and a pattern.

How it works

Learn a note. Point it at a key. Go live.

No scripting. Close the window and it fully quits. Nothing stays in the tray.

Plug in any MIDI keyboard or pads

The app lists whatever you connect. That’s the whole setup.

Hit Learn, then play

A note, a chord, or a rhythm. MidiKeymapper captures it.

It fires in the background

Minecraft, OBS, Discord, the desktop. Still runs when this window isn’t focused.

Fired in Minecraft · W

Same Learn button. Four different ways to mean “this is the trigger.”

Note

One key, one action. The simple path: a piano G is W.

Chord

Play a handful of notes together. C minor can switch an OBS scene.

Pattern

A sequence in time, as many hits as you play. Pitch optional.

CC

A knob or slider. Twist it, slide it, or record a shape.

Knobs & sliders

A fader can be a shortcut. Or the mouse.

Same Learn button. Twist, slide, or record a shape, then fire a key or drive the pointer while an app is focused.

Record a gesture

Move a knob. MidiKeymapper captures the shape and can fire when you do it again.

Drive the mouse

Two sliders, X and Y. The pointer follows even while an app is focused.

How you play it

The same notes can mean unlimited things.

You set the tolerances: how fast, how hard, how long a note is held. Same pitches can fire as many mappings as you need.

Macros

Chain a whole routine on one trigger.

Shortcuts, typed text, waits, mouse, open a URL, launch an app. Drag steps onto the chain from the right. That’s the builder.
