What I've "sensed" so far is that the signal is louder in Studio One. How that happens??? I don't know enough about Studio One - this is the first time I've actually tried a real recording. However, when I export the Studio One it reports the signal is peaking +3db and clipping as its exporting it, but in Sonar the original signal is only peaking about -1db (I raised the level from the original recording that was about -12). I imported the track into Sonar and I can see that its clipping in spots. But the "raw" track in Studio One is not clipping.
I had other tracks (7 more) that I exported from Sonar and imported to Studio One. I don't "hear" a difference in those tracks (Bass, Lead Guitar, Pedal Steel and two Vocal tracks). Maybe just a fluke with the Bass drum track?
I'll have to experiment with a different song's Bass drum track. I've got some other "live show" recordings I did of our band last September. I recorded the drums the same way, an SM57 on the Bass drum and an overhead Ribbon for the rest of the drums.
