Voice 1 seems to be bad, so I've turned it off.
With Voice 1 Off, This is the status of Autotune
VCOs- PASS
PW - PASS
RES- PASS
VCF- PASS
VCA- FAIL
(With VCO1 on, all the above tests FAIL.)
On Master Page, Page 2, Voices On.OFF, All Voices show FAIL
DAC Tests
DAC Mono- Page 2 LED blinks about 2 times per second (Is this good or
bad? Nothing in the service manual about the blink Rate.
I hear a Buzz in the audio- which sounds like a sawtooth going about 5
times per second.
DAC OFFSET- Page 2 LED blinks about 2 times per second. Good or bad?
All other tests on the Service Page are OK
Out of tune Points to the DAC, pray it's is not failed because it's
even harder to find than the CEMs.
Can you tell if the filter still sweeps well? Or - Turn off the VCO
waves and turn the resonace all the way up,and the cutoff all the way
down, Mod by keyboard to see if you can play the filter like a voice.
Self resonating? Yes.
Once we know if it's the DAC or
not we can go from there.
Also- after hitting untune on the DAC page, then doing auto tune, my
VCOs sound much better. In tune, that is.
So- it only looks like Voice 1 is fialing, and the VCA test.
Now what ?
