DR elmore - Yes, we are using RMS. Thankfully, the learning curve was practically non-existent, at least for me. However, since it's basically a MIDI-based program, some tweaks require(d) adjusting each and every instrument setting in a particular section or measure(!). It's not yet set up with the availabilty to do a "mass edit" on an internal section. Consequently, when I found certain "events" were set too high, too low, too fast or too slow, well... Many more keystrokes were required than I would have liked. The big "culprit" were some of the preset tempos. Yes, the box follows you as you play, but if the preset tempo is set slower than you would like - and in many cases much slower than it ever should have been - then the program and computer is prone to "hiccup". (Since the duration of a quarter note at M.M.=120 is longer then it would be at M.M.=204.)
