Found this out tonight at rehearsal, I do not usually use a tap tempo setting.
Anyway, using my usual delay patch, switch to play mode, change delay time to ¼ and tempo ON, tempo light is flashing. Tapping the tap switch does not change the tempo.
I have to turn tempo off , tap the tempo again then turn tempo On for it to update the speed.
I tried the same with one of my delay patches on the Pitchfactor and it works fine.
Both are v3.0
