Argh ! That's worrying.

Actually I have an expresion pedal (BOSS FV-500) connected to the pedal #2 input, but it totally works fine. All connections are OK.

When I used the V4.0B, the presets sound correctly too, as before (V3.51).

I add I have already re-install the full release & the issues remain…

Should I use the V4.0B instead ?
