Noise Issue
-
I'm debugging a build for a friend and not getting any noise to the clap or snare. I think it's due to a lifted through hole at pin 5 (bottom left) of the noise op amp (not having an op amp in the board results in the same sound) Using DSL man's schematics i have continuity to R124 but not to R132 or C33 as it seems as I should. Is that most likely my issue and if so is there a file showing the trace lines so i know where to cut into the board and jumper? Cymbal and closed hat get noise but the closed hat doesn't although that may or may not be a related issue.
Have you checked the eagle files?
Looking at the schematics, pin 5 of U24 does indeed go to R132 and C33. A lot of things happen between pin 5 and R124 though. Also, AFAIK the HH and CY don't use the noise from the noise generator, so your problem is probably somewhere close to U24.

Had no idea you could turn a trace overlay on the eagle on. Thanks for the tip
