MIDI Out and Recording
By the Forma Labs teamUpdated March 2026
Filament can send generated MIDI back to your DAW, record the MIDI it creates, export or drag that recording as a MIDI file, and pass a cleaned performance into MuseScore Bridge.
Three MIDI Out Workflows
1. Output Row MIDI Routing
Set an output row destination to Host MIDI Out when you want that row's processed notes to leave Filament and feed another DAW track or instrument. This is real-time routing: the row still follows its keyswitch, voice-layer, matrix, and module settings.
2. MIDI Recording, Export, and Drag
Use Filament's MIDI recorder when you want to capture a generated performance, then export it or drag it into your DAW as a MIDI file. The export writes one track per output row and uses row names as track names.
3. MuseScore Bridge
Use MuseScore Bridge when the next step is notation rather than a DAW MIDI region. Record the performance, clean timing and note lengths, map rows to staves, then send the result into MuseScore.
Recording in Plugin Mode
In a DAW, Filament records against the host transport. This keeps the capture aligned to the DAW timeline and tempo.
- 1Arm or start MIDI recording in Filament.
- 2Start the DAW transport and perform through Filament.
- 3Stop the DAW transport. Filament finalizes the recording so it can be exported, dragged to a DAW track, loaded into the Clip Launcher, or used by MuseScore Bridge.
Recording in Standalone
In the standalone app, there is no DAW transport to follow, so Filament provides its own recording controls.
- •Set the recording tempo before recording.
- •Set the time signature used for the MIDI file.
- •Enable the metronome if you want a timing reference.
- •Use count-in when you need time before capture starts.
Exporting and Dragging MIDI
After recording, use Export to save a MIDI file, or drag from the MIDI recording control directly to a DAW track. Drag is useful when you want to quickly turn the generated Filament performance into editable DAW MIDI.
If you only need real-time MIDI routing, use an output row set to Host MIDI Out. If you want an editable MIDI file or DAW region, use recording, export, or drag.
