Exports prefer browser-native MP4 when available, with WebM fallback. Higher quality makes larger files and may use more CPU.

1. Load clipsDrop video or audio into Library, then use AUTO FILL PADS or tap a pad and choose a clip.
2. PlayUse pads, keyboard keys, MIDI, or the sequencer. STOP stops playback and recording.
3. LayersLayer presets are the fastest way in. Keep Layer 1 as the main clip, then use upper layers for fades, hits, and blends.
4. RecordPick aspect and quality in REC, hit START, then trigger a pad. Export starts on the first visual hit.
