Hi Folks,

RE: The Four-pot board used on the Control-X modules.

This is correct. I use two op-amps per reversible attenuator circuit,
and with an optional trimmer to set zero position too.

to that summing amp. That is a pretty easy mod.

No need to mod. This resistor, and input solder pad, are already there
because I use it on the 2U version of the VC-ADSR module. Each output
stage of the four-pot circuit board is summing stage to allow an
additional external CV to be added to the main signal path.
