Speaking of Cakewalk, Mac OS X 10.5 Leopard users can now use Dimension Pro and Rapture with Apple’s latest OS. (I have to admit, I was unaware they weren’t working together, but there you go.) That’s not the interesting news, though. More unusual: Cakewalk’s SONAR demo was on Windows XP running in Boot Camp on Apple hardware — a Mac Pro tower beneath the booth and a less-discreet pair of Apple Cinema Displays. MacBooks demoed Cakewalk’s soft synths natively on Leopard. I still have no audio-specific reason to advocate upgrading to Leopard at the moment, but good to know. And it’s clear that the once mostly PC-only developer is now making sure its instruments get shared by both platforms.
