Expression Pedal is inactive until B3 note is played "LOUD"

During a live performance, I switch to a B3 patch during the transition between songs. I move the expression pedal all the way down so that I can ease into the song quietly. As soon as I hit my first B3 sounds, IT’S LOUD!!! Ooops. After playing those first notes, now the expression pedal works. My undesirable workaround is to turn down the volumn of the AstroLab, hit a few notes, then turn the volume back up. Now the expression pedal works.

Any other way to make it work immediately after switching to a B3 patch?

HI @EnjoyRC
Ouch, that’s a strange one for sure!
I’m guessing you’ve already tried ‘wiggling’ your expression pedal back and forth a few times to see if it latches correctly?
Maybe save the offending patch with the pedal set to the lowest value and use that instead of the current B3 patch?

HTH!
