George: Thanks for the detailed information about the new 2000. I definitely want to audition one. I'm a big midi file user---hence the reason for the questions/concerns. I'm sure you've played midi files where controller information is embedded in the file to allow volume changes, etc. in real time while the song is playing. Often, I find, one instrument part or more is way out of balance for my tastes. If parts or volume levels are changed while the song is playing, they will default to their original positions/levels when the song is replayed. Do you know if the 2000 can void or override such information that might be in a midi file? Any information is very much appreciated.
