Sorry Jazaddict, the Conductor function does not work reliably (at least for me) with Real Tracks and PG seems to remain silent on the subject. I'm a long time BIAB user and fan, upgrade at every offering (now at version 2012 build 349)and use it weekly in a live standards-based jazz setting. Being able to change the number of choruses on the fly would be terrific, but the Real Track sounds are so incredibly good for jazz please don't let this relatively small issue keep you from using this great program.
