Description

Only lets Sustain Pedal MIDI data pass through.

Instructions for controlling multiple keyboards with one pedal:

1. Make a midi track with an instrument for each keyboard, and set the midi input to the corresponding keyboard.

2. Make another midi track for each secondary keyboard (the ones without sustain pedals), with the MIDI Sustain Pedal Filter device.

3. Set the midi input of the Sustain Pedal Filter tracks to the main keyboard (the one that has a sustain pedal), and the midi output to the corresponding secondary keyboard track.

4. Record arm all the tracks.
