Hi Graham,

IMHO if you are familiar with Cakewalk then I would stay with the Mac. The only thing the 32 bit Realband has over Cakewalk is that it can use native BiaB files. I think Cakewalk is a much better choice then RealBand. YMMV

Also remember that you can use the BiaB VSTi in Cakewalk and possibly Garage Band.

This is just my opinion. I am strictly a Window's user and I have little Mac experience. Hopefully Matt, who uses both PCs and Macs will shine in on this thread.
Laughing at your mistakes lengthens your life. Laughing at your wife's mistakes shortens it!

64 bit Win 10 Pro, the latest BiaB and RB, Roland Octa-Capture audio interface, a ton of software and some hardware.
