Can you try using an external modulation source to see whether or not that works? I'll take a closer look at your pictures tonight if I get a chance to see if we can get it working proper for yougrm wrote: ↑Tue Nov 24, 2020 7:01 pmanyone?grm wrote: ↑Thu Nov 05, 2020 3:13 pmgreat that you found the source of the problem, maybe that is the same issue as i have.jkammerl wrote: ↑Sat Oct 24, 2020 6:43 pmThanks for the quick response! I found the problem.. The LFO signal first goes to the IO board (since it can be replaced with an external CV modulation source). There I found a problem with the header on the control board side. Once I fixed it, everything worked!
could you please specify where the problem on your build was?
i have checked continuity and that is ok for all pins.
DLY IN is connected to the input pin (tip) of the CV DELAY socket.
DLY.SOURCE is connected to the switch pin of the CV DELAY socket.
and here's hopefully useful pictures of the full mainboard and the I/O board.
(one thing i can spot is a slightly melted 470nF cap, that i touched with my soldering iron, but usually they survive when it happened before. or could that be it?)
Took a look at the images, everything looks fine to my eyes. The wiring between the jacks and the I/O board seem fine, but that is something you could look into. It might be that the CV Modulation input "thinks" something is plugged in, and therefore isn't routing any modulation.
