Nano cortex + midi footswitch volume issue

Hi!

I have a problem with random preset volume increasing when switching presets with m-vave chocolate via midi. It happens sometimes, ~1 of 7 switches. I tried different methods of m-vave chocolate programming, default and custom pc commands. Can’t find out whats wrong. Latest nano cortex firmware installed (2.2.1). Any suggestions? Thanks

I got them, too.

So far I can’t be sure, why they occur.

If I Switch between presets the volume boost is away instantly
