Question: A compressor with lookahead that reports its pdc, someone said I should put this in code pdc_midi = 0; to prevent midi from being delayed but I thought this is just a compressor that acts on audio, doesn't JSFX by default prevent MIDI delay, especially since this is not a midi effect. I'm a little bit confused about this whole thing. Is he right?

    If you set pdc_midi=1, then MIDI will not be delayed. If you're passing MIDI through, leave pdc_midi=0. If you're using the MIDI to control the compressor, or the compressor to modify the MIDI, then you'd want to set pdc_midi=1, and manually delay any passed-through MIDI.

    The compressor has no midi capabilities at all, it only has lookeahead that it reports to host. it acts on audio and has no midi control functionality. So should i delete that pdc_midi = 0; line from code or keep it. All i want is the compressor lookahead, report to host, but im not sure if this affects midi.

    pdc_midi = 0 is the default behavior, you can leave it in or delete it, doesn't matter. just don't set pdc_midi = 1.
