It seems to have fixed the auto-scrolling problem with the playback cursor. By the way, that trace I just sent you was done without your two latest patches applied (I was in the middle of the auto-scrolling experiment when you committed them). I've now applied your two patches and tried again with sweep-selects in the track editor and with sweep-playbacks in the matrix editor. My first impression is that the auto-scrolling acceleration is less smooth than it was. I now get the odd jumpy acceleration of auto-scrolling almost every time I do sweep-playbacks. William |
