Welcome to the TS2K Experience, Andy! You'll enjoy this rig as you begin to understand it's many features. It's a great digi rig :-) . As another email noted, take a look at using the "packet" filters (menu 50A). I think you use HRD and you can do macros in that app similar to MixW2 to enable and switch the filters. I use that almost exclusively (instead of the Lo- and Hi-cut filters). The best is to experiment with it and see which works best for you.
