Thanks everybody for your help.
Well it seems to work now, I’ve installed the cable and the buffers have cleared. I’m getting clocks on D2. Haven’t tried gates or triggers yet.
However I have hit another obstacle.
I’m trying to calibrate A1 and have watched the calibration video 5 times now. I cannot seem to change the CV output. It is stuck at approx 5v on all channels. I have AOUT selected on the right of the CV config screen. Scrolling through the CV outputs and changing the calibration parameter seems to do nothing to the voltage coming out of the A1’s outputs.
Perhaps I am missing a step somewhere?
At least I am making progress.
