Reaper Setup

By the Forma Labs teamUpdated March 2026

filament is an instrument plugin. Load it like any other virtual instrument.

Setup

  1. 1Create a new track (Cmd/Ctrl + T)
  2. 2Click the FX button and add filament (VST3)
  3. 3Click the instrument slot on an output row to load a plugin
  4. 4Select a plugin from the VST folder — it will be added for quick access
  5. 5Connect an input voice to the output row to hear sound

That's It

filament hosts instruments internally. All routing happens inside the plugin — no external MIDI routing or track folder setup required.

Tip: Set the track's MIDI input to your controller and record arm the track to receive MIDI.
