I'm not sure if I understood your question correctly, but lowering the OPEN and/or FORCE slider (if CV is applied) should make the sound less bright, as it passes through the internal low-pass filter.
You can change the resistance of R43 (left channel) and R68 (right channel) to - let´s say - 33k to achieve a darker sound over a longer knob range. Just ensure that the filter still fully cuts high frequencies when turned down, if that’s required.
Hi Nikita,
