UPM is a basic performance manager for PC (mac?) use (if it is the same I´m thinking of). You can´t edit any styles, you can just name/rename and sort your performances. This is anyhow very handy sometimes, because it is very time consuming to do this directly on your keyboard.

I´ve seen an "UPS editor" somewhere on the net. This is a performance editor for PC. UPS lets you change everything that is changeble in a performance. Without changing the actual style itself it is possibel to save some style editing in a performance though. Ex. volumes, sounds, parts on/off.
