Do you mean that the rest of the kit is not hitpointed, sliced and quantized? Then you should not use hitpoints and quantization on the OH.
If the OH indeed is from the same take, and your problem is that the transients don’t align with the rest of the kit then you need to move the INDIVIDUAL TRACKS in time with the OH track (one track at a time, the whole track in one go, not by using hitpoints), since the OH contains all the sounds of the different close miked tracks and sometimes two or more together on the same beat. If you do the opposite, say you align the OH with the kick drum then you still would not get, for example, the toms in phase because they were closer to the OH mikes when recording.
If you already knew this then I’m sorry to have taken you for a newbie
Or have you already used quantization individually on your close miked tracks? Since you say you have created a groove map, I suspect you have not.
But if you have then I don’t think there’s any rescue, you’ll have to read up on the new folder group editing functions and multitrack quantization in the manual and then start all over.
