All last year I’ve used SurferEQ2 with no real problem. One particular mix last year I used it on half the instruments. I would have MIDI notes lined up perfectly (to the sample) at the starts of notes. To be extra safe, I’d shift the MIDI clips forwards some ms (sort of a look-ahead that doesn’t mess up latency). Everything worked as expected, no strange audible artifacts or anything.
I haven’t touched that session since November, but then I open it today and solo some instruments and there’s a vary audible blip noise that happens every time a SurferEQ2 node starts up or moves. The blip comes in less than a half-second after the note starts (lookahead is off). This was NOT there in November and I haven’t done a single thing to any of these plugins nor my DAW to make this happen. I haven’t even touched the session…
I decide to try it with look-ahead ON and a different blip is there. I then turn look-ahead OFF and manually move the clip ahead 20ms (same latency as look-ahead) and another much louder blip happens.
