GLD an CDM 32

Is it possible to Control the gain of the CDM 32 over The Midi Channel 1 to 32 in The GLD???

I warnt to Use The CDM 32 PreAmps and send The Audio Channels via Dante to The GLD back to The CDM 32 and use the Outputs!

It is no Problem to do. this Controlling The CDM via Laptop but I warnt to have The gain Button on The GLD.

Best regards ROBBY
