To control external instruments within Cubase you must use Scaler 2 as a VST plugin and route Scaler 2’s MIDI output onto the track of the instrument you wish to control.
1. Load Scaler 2 VST onto an instrument track and the instrument you wish to control on a second track.
2. Change the MIDI input of the track you wish to control to Scaler 2- MIDI Output
3. Arm the Scaler 2 track so it receives MIDI from your controller, and turn on monitoring for the controlled track.
4. Scaler 2 MIDI output is now routed to your instrument.
