Recording processed MPE Pitchbend Messages from Fluid Pitch to Reaper Timeline through "Input FX"
In this video, I'm inserting Fluid Pitch in the "Input FX" of the Synth instrument track and recording the processed output of the Fluid Pitch directly to the Reaper's timeline.
For other DAWs we can use Fluid Pitch Standalone and record it to the timeline via a virtual MIDI port between the standalone and DAW.
