I can see why but when pedal builders design compressors they have a "it's always on" trail of thought as that's what most people do, set it to perfection then never touch it again. The only thing I know that is close is the Source Audio EQ, granted it's not a compressor but it's the only pedal that I could think of which is close.
Source audio have a great set of pedals which are all MIDI compatiable and modular, currently harvesting my fair share of them!
