Hi there folks, I just bought a brand new computer. I went from using Logic Pro on a 2009 MacBook Pro with 8 gb of memory to a 2.44 ghz 12-core Mac Pro with 24 gb of memory. I just started working on a song that was stalling quite often with Logic on the old computer and 1) find it still stalls! and 2) often during playback it suddenly becomes unresponsive to the stop button (either moused on the screen or hit with the space bar) and just keeps playing. What should I do? Is this a known problem? At first I thought it might be the Abbey Road plugins, which do not work well in 10.7 or 10.8 (I'm running 10.8.1 btw). But after removing all instances from this song and deleting the files from the computer Logic is still misbehaving badly. The only other plugins I have loaded up on this computer are Valhalla room, Valhalla Shimmer (which I'm not using in this song), Kontakt (which I'm not using with this song) and Waves CLA-2a/3a/76. If anyone can help I'd be eternally grateful. This is so frustrating!
