I use Cubase 5 on a Mac desktop, two years old, has 4 GB of RAM and a 2.66 GHz processor. Whenever I make a project and play it, it gets to a certain point where the ASIO Time bar on the left of the transport panel spikes, the red light above it comes on and it locks up. The project continues to play, but with no sound coming out of it, until suddenly all of the notes that should have played in the time that it froze come out at once, which certainly isn’t good for my hearing! (although whenever it happens, I pause it or mute my speakers/earphones). It is still very annoying though, and I can’t really make any decent-sized project without this happening (I make orchestral music, and can’t get to an appreciable level of content without the overload problem occurring. It seems as though it only takes about seven or eight tracks to cause this to happen, even less with faster pieces).
Earlier on I had it running with the activity monitor in the background (nothing else) and the CPU usage on it was actually going to more than 100%. The green section of the chart showing memory usage, which represents the free portion, was very small.
Now, I am considering getting some more RAM for my machine, but it is a significant investment and I want to be sure that it will produce an improvement, as 4 GB is perfectly adequate otherwise. Should I get more RAM, and if so, how much would people recommend?
Any help would be greatly appreciated.
