Calibrating with Pacemaker on
So in the instructions, it indicates that all that is needed to run the device with pacemaker off (with jumper wires as they are) is just jumpers to the tune pot. Is that it? I am not getting any audio out but CV is getting to the board and I can measure the OSC changing when I play different keys. I sense I am missing something

Re: Calibrating with Pacemaker on
sorry about that, i think the instructions need to be descriptive. the audio comes out on J6, so you can probe for it there while tuning - it wont come out the filter or VCA output though. you mentioned you saw the OSC changing, with CV, so it sounds like board is working.

Re: Calibrating with Pacemaker on
ah. Figured it must have been something like that. Working fine. VCA seems very clicky, is that to be expected?

the VCA might be a bit clicky on some, as there wasnt an option for "selected" transistors. so the offset voltage could be a little higher. the offset voltage trim mod should take care of it, if its not tolerable.

That's what I was hoping for. Which parts/pins should get the trimmer?

Re: Calibrating with Pacemaker on
you can put the resistor/trimmer on J9 - pin1.
