Hi Tom volume - Firmware or hardware?

Hi there.

I have a quite high Hi tom volume, with only a little difference between accented note and just a normal trigger. I can see that I have much more power on the accent pin on IC114 compared to Mid and Low tom.

IC114
Pin1: 1.9V no accent
Pin1: 2.9V Accent
Pin12 and 13: 1V no accent
Pin12 and 13: 2.4V Accent

Is this a firmware issue or something hardware related?
Im on firmware version 1.023, and It could be nice if that was uploaded to github.

Cheers

Mikkel

i have the same thing. V1.020
i think it is firmware because all other accent levels are roughly around the same value.

i also notice that if you stop the sequencer for a few seconds and then start, the first beat is also louder then the rest after that .

the accent level is high in stop mode and has to come down when running ,that's why the first beat is louder.

i put a resistor 10Meg in parralel with the first capaictor to ground in the accent signal chain comming from ic 111 and ic 114 to solve this issue.
(only for the analog sounds, the digital ones don't seem to have that issue.

Thank you.
So a pull down resistor on every accent out.

Will try it soon.

Yes, but that will only fix the loudnes on the first beat. The hi tom will still be to loud then.
