Here's a couple of question about Sonar settings: In the Options->Audio settings, there's a check box that says "apply dither". What does that mean, and should I check it or not? My buffer size is set to 64k, and currently I'm using 6 buffers. Is this a reasonable setting with a fast CPU and a gig of RAM? In the Options->Project, there's a checkbox that says "Patch/Controller Searchback Before Play Starts". What does "searchback" mean, does that mean it's going to look backwards in the track for any patch/controller changes and try to apply them before resuming playback?
