Well 40 You should not be able to even hear it. What is it using for the count in.. the metronome?
That might be what is happening. If you have Sonar set to count in it's possible the metronome is part of your export. If so then un checking that will be global to all songs.
Because I master all my backing tracks in Wave Lab that is one of my tasks. I cut the song to 1 beat ahead of the first tick and I run a quick check of the level. I set all of mine close to the same at -30db RMS.
I find a hi hat is less annoying if the audience is going to be hearing it.
40 is quite low, but audible enough for me to hear thru the monitor on stage, and not bother the audience. Hi-hats are lost to my ears in a noisy place.
The count-in is simply drum sticks (on a MIDI kit), no metronome involved during playback.
Edit: As a test, I deleted the count-in (the four stick hits); not the measure, not the CCs or anything, just the notes (G2 x4). Exported it to WAV, and it played with no volume fluctuation. I half expected the first few beats to be super loud, but no, it was fine. When I put those notes back in, the problem comes back.
So again... why would those first 4 notes be at 127 when exporting? I can see no settings that would cause such a thing to happen.
