MIDI works (note displays on screen when MIDI note plays)
No audio from output or at any of the poles 1-4
OSC pin has a high pitched whine, same sound as pin 18 of the atmega.
This sound does not change whether both Osc 1 and Osc 2 are set to none or to a wave. Does not change pitch when changing range.
Somewhat unrelated but I’ll throw it out there - the filter will play a sine note - I get sound from all 4 poles when cutoff is at 64 and resonance is maxed out.
From what I understand from other forum posts this has something to do with MIDI, but MIDI seems to work. Pin 6 of the optocoupler is at 5v at rest (havent tested with MIDI notes)…
Ok, I get regular Osc sounds when triggering the test note. I guess I stupidly thought the test note continued between restarts. I’ll keep troubleshooting from here… sad that I’ve become the dreaded Screwupper in the Shruthi caste system…
Long story short I have a hand-me-down iron that outputs at 600 degrees with a self regulating tip and I think that might not be hot enough to flow certain joints properly. Even when I saw a shitty joint from the topside, I couldnt get it to reflow from applying solder on the bottom. Lesson to take away: just buy a damn adjustable temp iron like everyone recommends. what you lose in money youll save in sanity/hair/time.
sanity/hair/time… kinda sounds like space time. dont rip the sanity/hair/time continuum. ok im done.
Haha - glad it’s all working now. After getting a new soldering station, I am 100% in agreement with the savings in terms of sanity/hair/time being worth the extra money spent. I also back your sanity/hair/time continuum theory. Time has already taken some of my hair away, I should do my best to not let sanity take any away either!
