Or beg and plead Sends-on-faders-Andrew to finish writing his gain-sharing MIDI Studio Manager software for Yamaha mixers. :-/
Oh I really wish he would!
Andrew's "automoxer" program for the LS9 actually works pretty well, HOWEVER there are a few bugs and the program occationally crashes. The good news is, once set up and running, I've never had the program crash PROVIDED I did not make any parameter changes within the program during an event. So, the key is, set it up the program how you want it, and don't touch a thing during the show! You can do whatever you want on the LS9, but leave the computer alone.
