Hi Eric
Ken will probably chime in on this but have you done the Mods to the PCB as detailed here ?

CGS101 is the Quad VCA used in the DCSM.

Hey guys, I haven't heard from a single builder who built one of these before, so I may be treading foreign territory. I built up the DCSM, and it works, but not nearly as what I would imagine to be correct. For one, I can't seem to trim out the distortion, and the gain pots on each channel only begin to have any effect after about 60% through their travel, at which point they have about 20 degrees of movement at most before they distort. The sound of the distortion is great, though, and I can work with these touchy settings, though may consider changing to an anti-log pot if my logic is correct.
The real issue is that the center of the pan pots is not the center of the panning curve, particularly far off for one channel, and it is different for both channels. Center pan has such a narrow travel before biasing entirely to one side, maybe about 10-15 degrees on both sides. Do I just learn it and work around it, or is there another way?
Thanks,
Eric
