Thanks for your answer.
I fixed my rotary encoder with some epoxy and secured them with wooden wedge. Theses encoders don't like to be pushed.
Concerning the sequencer button, I solved the problem by loosen a screw of my enclosure, the actual button wasn't faulty.

Hello

,
I have a problem with my instrument selector (16 positions encoder), contacts seems odd... some positions doesn't work.

Thank you

I probed my IC1 and there is no signal from pin 1,2,3,20 trig_cpu trig_out1 2 3.
I checked the quartz i got the 16Mhz pseudo sine.
On other pins I got some square/pulse waves.
Could you help to to debug it ? Is it possible IC1 fried or bad programing ?
Because the sequencer seems to work buttons too..

electrosymphony

Ok I have an oscilloscope now do you have any debug process for IC1 ?
