Yes I have a top of the line I7 brand new with 8 gigs of ram and I am getting this access violations a lot and out of the blue in REAL Band 2011, the software is buggy , I ask here in this forum a few times about but never got a real answer. I was hoping the patches will fix it but I applied all of them and still get this weird access violations out of the blue,which never happens with my other music DAW Sonar X1, I hope Peter Gannon makes a real commitment to solve this issues since RealBand has the potential of becoming a serious platform but until the software code is more stable I'm afraid we will be stuck with these issues, another thing is that you can run Band-in-a-Box and Realband together just with the wrapper but these also seem like a work around these app needs to be re-coded to take advantage of the new 64 bit platforms of today.
