Is there such a thing as a polyphonic compression pedal? The idea is that it doesn't just compress the overall input signal to the output signal level, it also independantly gain/suppresses separate notes within said signal. My particular scenario is as follows, Hit a strong open chord Then hit single notes on a higher string while the open chord still rings The standard compressor suppresses the strong open chord signal. But as a result, when the signal notes are played, they receive the same amount of total signal suppression even though they don't need it, so they sound very faint in the mix. If there was such a thing as a polyphonic compressor, it could gain up one note while suppressing another. If no compressor is used, you just get the opposite effect, the open chord is too loud relative to the rest of the playing, the compressor is desired/needed to limit the volume spikes fronm hard hit notes. Also, since i play a lot of palm-mute metal, the compression is necessary in order for palm mute notes to get gained up before entering the pre-amp, otherwise they are weak and flubby. So 95% of the time I need a compressor and it does what I want. But 5% of the time I wish there was some way for secondary notes to push through some sustained notes/chords.
