I use detect silence to reduce bleed in instruments recorded live. I frequently apply it to kick, snare, toms, sometimes HH, guitar, vocals, and horns. I notice that I fairly consistently use the same starting settings for particular instruments, e.g., kick vs snare vs. vocals/horns). As I get better at this, I fine tune the minimum open/close times, pre and post roll, fade time, thresholds, etc.
It would be wonderful to have at least user presets for detect silence, different presets for different applications.
(Yes I also use SL8 pro).
