Yocto hihat and snare problem
Posted: Sep 2nd, '18, 20:54
Hi, I bought a used Yocto and have already fixed a few problems. I repaired the circuit around the hex trigger, tuned the cowbell (with changed resistors) and added circuitry for the noise generator to produce proper output (per Masuto's instructions).
The hihats work fine, but there is a dominant resonance I don't care for. 808 samples don't general have this. I found one dead cap around the schmitt trigger I replaced and the outputs now look fine on the scope. I couldn't check the frequencies though. Is there a table with the correct frequencies put out (besides the two for the cowbell)? Didn't find it in the service manual.
I added a trimpot for the snare noise, but there is a little top end lacking compared to samples. Would a slightly smaller value for C54 help here?
Thanks!
