I do not agree with a lot here. Parallel compression means that two signals are summed, one is uncompressed, the other compressed. This is nothing to do with ducking, or sidechaining. MPC1000 does not have side chain in the compressor, so there is no option for sidechain techniques like ducking, de-essing ect. To use one side of a stereo pair can be ok, depending where it goes after, say to desk with panning is ok, but to do this in a stereo field it is not a good idea, IMHO. ie it is not stereo. So all you need to do is actually route your signal so as that it goes through compressor and also does not go through compressor at same time, then summed to stereo pair. That is what you should think for parallel compression through MPC FX.
So I would say there are a few ways. One obvious one is to just copy track. So with two copies you can have one through FX, and one not through FX, then summed to out. Phasing is issue of course. yeah you can send mono to a stereo pair out as 2 monos and feed it back into the inputs in L+R mode that gives you option to have FX on or off. But it is mono only this method. sums to stereo though. I tried it and its ok, but it stops me using my set hardware FX sends set up so do not do it. This is JJOSXL like. I still do not see point of using two FX slots. when it can be done with one. I use a PCL3200 hardware compressor and it has side chain inputs, but you do not need them for parallel compression. Sidechain is used for differential compression, ducking, de-essing. this thread is from the dead isnt it?
