MIDI controller not moving expression knob/slider. Only on or off

I have a homemade midi controller with an expression pedal that sends values: CC31 Channel 2 Velocity 0-127

I’ve verified in the Global MIDI Monitor that the messages are coming in

When assigning this to a widget I cannot get the knob or slider to move up/down. It only seems to stay at 100% value. Is there something obvious I’m missing? I’m trying to control a wah or volume pedal in helix native, and this same setup works in Reaper, but I can’t figure out what I’m missing in gig performer to get it working.

I’m new to Gig Performer and evaluating it to replace my DAW as a live solution. I feel like I’m missing something basic.

I just had a thought, is this happening because I’m trying to use MIDI Note Velocity changes to move the knob instead of MIDI Control changes?

Note On messages are handled in a different way than normal CC messages.
For controlling a slider you should not use Note On messages.

Thanks, that was exactly the issue. I reprogrammed my MIDI controller to send control value changes for the expression pedals and all is working.

In the past I had used ReaLearn in Reaper to remap Velocity to Control.
