here is some audio sample of the clone so you can hear whats going on and ref it with the times i have put for each sound.e-licktronic wrote:Mid tom issue: Could you check with a scope (or sound card scope) trig signal on Q54 emitter when sequencer isn't running and when it does.
Bd issue: Check C43 polarity
Cowbell issue: Need tune
Maracas/clap issue: trim TM3, is it changing the volume of noise source ?
HH issue: Is cymbal working ? could you check noise source on U3 Pin7 with a headphone or/and scope.

Ok I have finally had some more time to get this all sorted, here is where i'm at.
Master Volume - Is now playing much louder than before, there is a high pitch noise with every hit.
Mid Tom (@58sec) - I checked the emitter on Q54 and it looks the same with or without the sequencer running. It's not self osc now
but there is the click ghost sound still playing in the back ground and it still has a pretty long decay when tuned down low.
BD (@0sec) - The polarity of all the transistors are the right way, it just sound like the decay is to short.
Cowbell (@2:03) - I changed the resistors as mentioned in the cymbal section of the build and now it's in tune (well close too hahahaha).
Clap / Maracas (@1:45) - I trimmed the TM3 and now the clap and Maraca comes through and sounds as it should, but there is still a constant white noise in the background.
Cymbal (@2:11) - still nothing, just a high pitch noise
hi hats (@2:15) - no change after the change of the resistors.
