I find that I am no longer able to generate a Real Track on the strings channel, probably since the latest build of BIAB 2009. If I select any Real Track to use on that channel it will not generate, and the song begins playing with the strings channel still empty and not highlighted. If I open a song file made in early July (with an earlier version of BIAB 2009) that used the strings channel for a Real Track, it plays normally. Rebooting and relaunching does not solve the problem. The computer is a 2009 Mac Pro running 10.5.8, BIAB is 2009.5, build 7. Has anyone else seen this?
