what do you mean by "the front panel doesn't"???

I don't think the plonk will make any sound unless it is triggered!

what other modules do you have? the only rack you have made here is a single small row of 1u which is empty!

did not turn on the front panel! I have a beatsteppro, other modules too... that's not the problem...
the situation with the plonk that is my doubt. all the lights turn on, but the front panel doesn't, the button that would trigger the trigger doesn't either. when I send trigger, or cv, it also has no reaction.
ps. I'm going to build my case here at MG haha
