Btw, hi to Denny C and the other listeners! If I may, some hints about the sidechain:
Mode 1: Compression with sidechain (Sidechain On, Compressor On)
With SC-Listen On turn the gain knob ccw to boost and use the frequency knob to find the instrument, then SC-Listen Off. Turn the frequencys/instruments gain knob ccw for more compression, cw for less compression. Mostly used ccw for dynamic/peak reduction. But if you want an overall compression without a particularly loud instrument triggering the compressor too much, then set the frequency for this instrument and use the gain knob cw, so that the compressor does not react to this frequency (of course then there is less or no peak level reduction possible for this frequency).
Mode 2: Used as EQ in the signal path
Again, with SC-Listen On turn the gain knob ccw to boost and use the frequency knob, then stay ccw to boost or cw to cut the frequency. You can additionally switch on the Compressor, which as far as I recall (not 100% sure with this) always reacts to the EQ'd Signal when SC-Listen is On, no matter if Sidechain is On or Off.
I think the compressor together with the sidechain EQ is able to handle a lot more than what is sometimes reported about it. But I agree, it is not as easy to use as the EQ.
