Hi CCTM
Thanks for your reply. My machine's spec is a 2.5 GHz Processor, and 4GB 1333 MHz DDR3. I'm using Mac OSX Lion, version 10.7.5. I've noticed that there is an update for Logic. I have 9.1.6, but I've seen that 9.1.8 is available. I've tried downloading it, and installing it, but it a message comes up and says I have to download it from the Mac store. I did download it from the Mac store, so now I'm stuck and don't know what to do. (could the problems be to do with not having that update?). I had a PC Laptop with half the spec my mac is, and even when my hard disk space was nearly full, it still took quite a bit of audio for it to glitch, but it never just stopped like my mac does. I didn't have any problems with any type of plug-ins with my PC. Yeah I have plug-ins such as Sugarbytes Wow, Fabfilter, NI Massive, Alicia's Keys, Albino 3 etc, because there's no way in the world I just want to use Logic's own instruments/fx. I want to buy Symphobia or Vienna Symphonic, but I'm figuring there's no point in wasting my money if things are already coming to a stand-still. I can't afford a power mac.
I'm going to read the articles now, and see if they help. I just didn't expect to have to do stuff like this, because I've produced music for years, and never had such a hassle. I appreciate your help though!! Thanks a lot.
All the best for now 🙂
