Dbl-click a note = pitch points Drag a pitch point = bend the curve The last point stretches the note Drag the > past the end = extend Dbl-click a pitch point = delete it Ctrl+drag = free pitch Amber line above a note = drag up for an LFO
Ctrl+drag = highlight notes Ctrl+right-drag = select pitch points Shift = add to the selection Shift+click a note = toggle it Delete = selected pitch points, else notes
Alt+drag a segment = arc bend Alt+click a pitch point = handles on / off Drag a handle = mirrored shape Alt+drag a handle = independent Shift = angle snap Alt+dbl-click a segment = linear again
Scroll = pan pitch Shift+scroll = pan time Alt+scroll = zoom pitch Ctrl+scroll = zoom time Middle-drag = pan both axes Hold a segment = grab the whole note
This mini demo plays a plain sine MIDISketch hosts any third-party VST3 inside MPE synth = polyphonic pitch bends, per note Non-MPE synth = draw bends monophonically Same easy sketching and tools either way
Space = play / stop Esc = stop all notes Ctrl+Z / Ctrl+Y = undo / redo Click the BPM and type a tempo Everything snaps Alt frees time, Ctrl frees pitch
The real MIDISketch grammar, ported. Sine voices only.The full instrument hosts your synth.Built for desktop. Touch comes later.

Here's What It Can Do

Draw Pitch Like a Line

Alt-click or double-click any note to give it pitch points. Drag points to bend, pull bezier handles to shape the curve, and hear your synth follow as you draw. Full MPE, per note, per voice. No other piano roll works this way.

Your Voice, Mapped to the Synth

Sing a line and print it as full MPE pitch curves that follow every bend of your voice, or as clean staccato notes. Then route brightness, mouth shape, and breath to slide, pressure, or any CC, and ride the filter with your vowels.

VOICE → MIDI · ASSET SLOT

MPE Controller Recording

Seaboard, LinnStrument, Osmose, Push 3: record pitch bend, pressure, and slide as editable curves, then fix single points instead of redoing takes.

See the Audio, Trace the Melody

Load a vocal or any recording, see its spectrogram behind the roll, and trace the pitch straight into editable MPE curves. Real bends, not quantized steps.

Any Tuning You Can Imagine

Just intonation ratio snapping, custom EDO grids at any division, historical temperaments, and Scala file import. Smart Root retunes chords from context. 12-TET is the default, not the limit.

Any Synth, MPE or Not

Load Serum 2, Vital, Phase Plant, or any VST3/CLAP instrument and hear every bend live as you draw. MPE synths get true per-voice polyphonic bend. Regular synths get global channel 1 bend, drawn exactly the same way.

Expression Lanes and One-Click LFOs

Pressure, slide, and pan as bezier lanes, per note, per voice. Drop an LFO onto any note or lane, set rate and depth, and it stays non-destructive until you bake it.

Chord Stamps and Custom Shapes

Stamp chords in key and arpeggiate them on the spot. Save your own note shapes as stamps, reuse them anywhere, and share them with anyone.

Non-Destructive Chop

Slice any note into 2 to 64 rhythmic subdivisions with gaps and velocity curves. Preview live, bake when you are happy.

MIDISketch Link

Open multiple windows and see each other's notes as ghost overlays in real time. Drag notes between instances to layer MPE parts.

MIDI That Travels

Standard MPE out of the plugin or the standalone. Drag to your DAW, export the file, or route the standalone straight to hardware and other apps.
