OK, I understand. You're hearing a delay in the equalizer's response, correct?
That could be an optical illusion. The automation nodes may just be offset. Try showing the bus waveform by clicking the Waveform Preview button (to the right of the Solo button) and then playing back the song. Comparing the automation to the waveform, are the nodes where you think they should be? Also, when you play back, does the Now marker move smoothly or does it jump?
