Hi,

When I set the value for addres 29 (DCO1) to 1, voice number 3 sounds
distorted. I don't have any schematics for the BIT One so I don't know
where to look. Does anyone have an idea what the problem can be, or
can anyone help me locate DCO1 for voice 3?

There are several options to reduce this:
1. Reduce the total output of DCO 1.
2. Reduce the total output of DCO 1 and 2.
3. Reduce the noise output.

If 1., 2. and 3. don't help, you porbably have a filter that's fried. 
It it occurs on the third voice, on all patches than you'll have to 
get a new filter chip.
Good luck,
Yoonchi

thanks for the reply. I already tried switching the CEM3328 of voice 3
with that of other voices, still the problem occurs. The problem
occurs on all patches with variable pulse switched on.
