first measurement: low tom (blue) and mid tom (red) accent signal at IC114 (pin12 and pin13):



second measurement: accent signal after the OP amp at the accent testpoint, again low tom and mid tom:



third measurement: env 1 testpoint low tom (blue) mid tom (red):



fourth measurement: env2 testpoint low tom (blue) mid tom (red):



fifth meauserment: env3 testpoint low tom (blue) and mid tom (red).



and last measurement the low and mid tom at the outputs, I accidently swapped the probes, red is low tom here:



the osc signals have the same level on both the low and mid tom. To me it seems that the problem is already at the multiplexer? Might also be an option to change the gain of the op amp circuit of the mid tom? Gonna give this a try later
