Mixermaps let you control the MIDI equipment they were written for. What you need to do is create a mixermap track in your arrangement. Load the mixermap (this is done from onw of the pull-down menus - I can't remember which one). Select the mixermap for the track you just created. Set your left and right locators a bar apart and double click to creat a new part. If you double click on that part to edit it, a screen with a bunch of faders and knobs and stuff will come up on your screen. You can then use your mouse to move the screen elements thereby controlling your MIDI gear. You can even modify them and create your own controls.
