Yes it has, thanks to everyone who replied. Sorry for the slow response I haven't been online lately. RB seems to be ok now, it was locking when i was trying to choose audio drivers. After setting up Biab successfully I have now manged to do the same for RB.

I must admit i am blown away by it, I can't believe that I hadn't come across it before. I always wanted a program that could just generate a reasonable backing track without me having to is for hours inputting all the notes. Part of the reason is because I have never liked computer based music software and have always used analogue hardware.

Once again thinks for taking the time to reply, it has been very helpful

Regards
