Yes - you all guessed right - want to do it live. Thanks for all the great tips so far...I actually have the equipment to do what Pat outlined - and it's great knowing that many of the parts are pretty simple as rharv explained. The fun, using midi guitar, is of course to find the right MIDI controller realtime parameters to change to make things sound like horns. I'm sure volume is important - and with a single horn sound, especially the sax, there are timbre changes that take place on a single note which I can hear but can't put into words. Now I don't expect to control all these parameters on a group of horns, but when soloing with one horn (pick whichever you will) - what are the Realtime parameters to map to my control pedal to make that horn sound authentic ?
