just finished two smr4 voicecards and the ambika board itself. Everything lights up. All knobs and encoders do what they are supposed to do. Menus, Sequencer, Midi, whatever you like works … except for the sound.
On both voicecards the red light is on and the green lights blink, whenever I send midi. I tried all Audio jacks, nothing. I even changes the TL072s … nothing.
I think I would need some troubleshooting tips on what to measure where?
I currently don’t have a SD Card. But I don’t think that should matter for the basics? And, and maybe that’s the problem here(?),
when doing the ‘Power supply testing’ I can measure everything correctly except the -8V on the blue pin on JP1
Or maybe I’m doing it wrong?
