Yikes... I see what you mean now. All the bass drum! At least the velocities are different.
I took a groove clip and offloaded it as a wave (no effects), then imported it back into an audio track to use Melodyne on it (polyphonic). I then exported it as midi and pulled it back into SONAR, and it was pretty accurate; BUT the midi notes being hit were not correct, so had to move the midi rows to the proper midi note. Even with a clean beat sequence this was more labor intensive than I would be willing to do for an entire song :( And this was *only* a drum track of 6 bars.
