now, by launching these clips, a different chain in your instrument rack can be selected immediately. there are lots of advantages for using this method instead of selecting from a knob: it is top-level - there's no need to dig through selection & device details to make a change. it is exact - you know which chain a dummy clip will launch without having to wrestle a knob to a particular value. it is modular - you can launch multiple clips at a time to change multiple chains across multiple tracks at once.

the same trick will work for audio effect racks as well; just use a silent unlooped audio clip instead of a blank midi track. this is fantastic for changing vocal processors or guitar effects as needed per song. for sets that will process external instruments with effects & plugins, you'll definitely want to be able to load presets quickly.
