Nah Greg, I do not know it all by a long shot, I was off by a mile on the drum map issue, i thought it was something else, then i never built drum tracks one note at a time i use either session drummer, or the program called PC Drummer, or download a rework midi drums from the internet. I also use audio loops at times. but the piano roll, i do not have the patience for that. I guess I thought that drum maps were premade sections that could be imported and reworked, I was confusing them with drum trax styles.
Part of the problem is that i have the old MC 2003, and have not upgraded recently, as i do far more work these days in the Program Multitrack studios, MTS does a better job for me and uses VST and VSTi aswell as DX plugs and instruemtns, without a wrapper.
I hope to upgrade soon to Sonar Homestudio, it do like cakes approach to groove clips and also time stretching for tempo change, and pitch change, of loops.
