Parallel compression is something Im just beginning to explore. Its not something Ive used much in the past, but Im seeing its potential for beefing up groups and whole mixes. However, if I set up a compressor on a send channel, rather than processing the whole signal via an insert effect, wont I get phasing? Also, if I set up compressors on several send channels and filter out certain frequencies on each channel (for example, roll off everything but the low-mid range on one, roll off everything but the high-mid range on another), then wouldnt this just be the same thing as multi-band compression?
