Transport Controls
Play, pause, seek, record, undo/redo, and MIDI export — what every button in the MIDI Maker control bar does.
Play and Pause
The Play button starts playback from the current playhead position. Pressing it again pauses. The scheduler looks ahead approximately one second and queues notes before they're needed — this keeps timing tight without blocking the browser's main thread.
When the playhead reaches the end of the arrangement, playback stops automatically and the playhead returns to the beginning.
Seeking
To jump to a different position in the track, open the Progression panel and click anywhere on the bar/beat ruler at the top of the arranger grid. The playhead moves immediately, whether the track is playing or paused.
Record
The Record button captures the studio's audio output in real time. Click it and playback begins automatically. When playback ends or you click stop, choose MP3, WAV or MIDI and the recording downloads to your device.
The recording runs through the full master bus, so the output includes the mastering chain — the file matches what you hear during playback.
Undo and Redo
The undo/redo buttons step through changes to the track arrangement. Each action that modifies the arrangement — clip edits, segment changes, instrument additions — is snapshotted automatically. Undo/redo does not affect transport state (play position or playback status).
New Track
The New Track button opens the setup menu, letting you choose a genre, tempo, and length and generate a fresh arrangement. The current track is replaced.
Download
The download button exports the full arrangement: whole-track MIDI with each synth and drum machine on a separate track, per-instrument MIDI files, and audio as WAV or MP3 — the finished mix or dry per-instrument stems. Everything imports cleanly into any DAW — Ableton, Logic, FL Studio, and others.
Audio downloads render offline through the full mastering chain, so the files match what you hear in the studio.
MIDI Out
The MIDI button — the DIN plug icon next to the transport — streams the track live into another DAW or a hardware synth as it plays, rather than exporting a file. See live MIDI out for setup.
