I´m reading for a while in this forum, and mostly, my problems could be solved with the existig threads but now, i go crazy!
I did a few more mods to my xox and i think i damaged anything, I´m searching for a few days but dont find the fail!
The cv out stays at 0,63V and dont change.
Due the other threads i think the problem have to be by ic9, ic11 or ic12!
I check the voltage references of the modified eagle layout and i got other values on ic12.
So i changed ic12 but nothing happend!
The sound at all octaves in the keyboard mode is always the same, a very short and low sound with a hard click.
Maybe anybody had a similar problem or could give me an advice?
I don´t know what i should do next!
I got the following voltages at IC12:
3: falling 0,07
4: falling 0,04
8: 0 --> so sum of R88, R89, R90 also 0V!! should be the same as pin9, pin10 and pin11
Thank you and have a nice weekend!
