It may work, but it might not. MIDI Expression expects 0->3.3V. While I doubt the over voltage would damage the MIDI Expression, it's not ideal. Does the pedal allow you to adjust it's output voltage range?

Your feature is available in the latest BETA version, linked in the BETA thread.

If you update to build 27 or downgrade to build 20, your choking issues should be resolved.
