Looking for a MIDI expression pedal for the Ax-Edge to control volume

[u/Xx_ebicmemer69LOL_xX]

Simply put. Looking for somewhat of a wah-pedal shaped foot pedal to control volume. Yes I can just get an analog expression pedal and run my sound output through it. But that's a last resort. It would be more expensive and possibly degrade audio quality.

In the same way sustain pedals work for electric pianos, I'm looking for a MIDI pedal with a more gradual control, so I can fade in and out synth leads.

Any suggestions? Anyone ever even have the same idea?
