Edit MIDI more easily

Open the piano roll on a MIDI clip and reshape notes without leaving Studio. Draw, select, or slice; fold to scale; ride velocity and probability; or let the Studio agent sketch a pass you still own.

  • Draw (B), Select (V), Knife/slice (K)
  • Scale fold, quantize, and humanize
  • Velocity and probability lanes
  • Agent compose: bass, chords, melody, arp

How it works

Using MIDI in Studio

A practical loop — not a feature checklist.

  1. 01

    Open a clip

    Select a MIDI clip from Arrangement or Session View. The piano roll opens with keyboard, grid, and overview.

  2. 02

    Choose a tool

    Draw notes, marquee-select, or slice with the knife. Snap to grid when you want precision.

  3. 03

    Shape expression

    Edit velocity and probability in the bottom lane. Fold to scale or humanize timing when the part needs life.

  4. 04

    Or ask the agent

    Describe a bassline or chord pass — session_compose_midi places material you can still edit note-by-note.

Tools

Draw, select, slice

Keyboard-friendly tools keep MIDI editing fast: draw notes, marquee selections, knife to split. Ghost notes from neighboring clips stay visible for context.

  • Snap grid control
  • Overview ruler for seeking arrangement time
  • Ghost notes from other clips

Feel

Velocity, probability, scale

Bottom lanes expose velocity and probability. Scale fold and quantize/humanize help you stay musical without fighting the grid.

Agent

Generate, then own every note

The Studio agent composes bass, chords, melody, and arps into clips. Nothing is locked — open the roll and rewrite until it sounds like you.

Related Studio surfaces

Studio is one product — these views share tracks, mixer, and devices.

  • Timeline

    Arrangement

    Arrangement View is the linear timeline where songs take shape. Place audio and MIDI clips on tracks, set loops and tempo, and keep the mixer beside you while you build structure.

  • Clips & scenes

    Session View

    Session View is a clip grid for sketching and performing. Tracks run as columns, scenes as rows. Fill slots, launch a scene, and keep returns and Main sticky while you explore — without committing every idea to the timeline first.

  • Levels

    Mixer

    The mixer isn't a place you escape to — it's a rail beside Arrangement and a strip under Session columns. Balance, mute, solo, and send without breaking the idea.

  • Plugins

    Devices & hosting

    Every track has a device chain. Load Rewire devices and scanned VST3s, open editors, audition while the transport runs, and bounce in place when a sound lands.

  • Separation

    Stems

    Stem sessions turn a source into focused layers inside Studio. Mute, solo, and level each stem, then pull pieces onto arrangement tracks when the idea lands.

  • AI assistant

    Studio agent

    The Studio agent works on your live session — not plugin source code. Describe a bassline or clip layout; it places material with session tools. You keep every edit.

FAQ

About MIDI

Can the agent write MIDI for me?
Yes. The Studio agent can compose bass, chords, melody, and arp patterns into clips — then you edit every note by hand.
Does the piano roll work from Session View?
Yes. Select a MIDI clip in a Session slot or on the Arrangement timeline — the same piano roll opens for editing.
