Lukas,
By SOURCE do you mean the MOOG and/or the MXR CC please?
There are 2 x OUT’s on the MULTIMOOG. Hi (-10dB) and Lo (+12dB) (respectively). I came out of the LO.
It sounds ok-ish to me but I am only a novice in this field. Though there it no EQ or anything whatsoever so just the raw sound of the MOOG. Just a jack lead from the MOOG straight into the soundcard.
Here is another self-creation I made using the MOOG. Same PATCH except minus all of the real time tweaking (and no SAMPLE & HOLD):
Much appreciated,
Paul
