envelope in lowtom and middle tom is level low

envelope in low tom tom and middle is very low compared to the hi-tom envelope, which is double the signal.
I have looked with oscilloscope, can someone tell me if you also see this?

Vic

Thanks.

i didn't look with a scope, but many have higher volume on the hitom compated to low and mid tom.

certainly is a problem trigger the instrument, then it is a software problem. Then Trigger depends on the level of the vca opens more or less.
Signal Trigg to envelope to vca.
trigger more, more volume

currently the highest drum has double trigger signal.
