Thanks, Mac and Zokk for your input. I wonder if the best place to add such a play list feature would not be in the BIAB/Real Band upgrades?
Zokk do you use a universal audio-midi interface to play mixed audio and midi files on stage? I think I am going to go from all midi files to the real band stuff as soon as BIAB 2010 comes out. But I think many, if not all, of the files will have midi and audio tracks and I have been told that an interface is the way to split them out before running them into my little one-man-band mixer. I am looking at the Roland/Edirol interfaces. I use a SD-20 Edirol sound module for the midi and it works very well for me.
