Thanks Rob but the plugin is still a sad piece of work in my opinion. I had not tried using it in several months but because you suggested it tonight I decided to give it a try.

1) ran standalone plugin
2) loaded my recent finished BIAB song
3) select bars I want to generate
4) right-click track I want to generate multiriffs from and selected Select Multiriff from this RealTrack
5) click Generate button
and...
6) CRASH

I get a yellow in progress box and then a green success box right before the program crashes and unloads itself.

I tried this 4 or 5 times and got same result every time. I'll give it another year as I am so sure it will be working properly then! (sarcasm!)
