If it is this that might be causing the problem, then what can i do? I need the vocal performance as it is, and anyway all the audio files in the media bin are there to stay, seemingly. Is there a way of copying the whole arrangement/track mixer with all the vsts to another project that i can in turn copy the vocal performance onto, so that theres not such a massive audio bin for the project?
But i'm also wondering whether the problem might be related to the 40gb Omnisphere sound library that i installed. it was only after this that i started getting real problems, even though i hadn't added any additional omnisphere vsts to the project. Also, even after wiping omnisphere from the face of my mac, logic is still having problems it didn't have previously. Very frustrating, considering i need to continue with the project regardless of omnisphere.
I'm going to double my RAM to 8gb (got a 2.3ghz i5 processor) to see if that helps, but i guess what i'd like to know is how to address the problem - if indeed it is a problem - of an overloaded audio bin, and the memory situation i've been left with my installing and de-installing a 40gb sound library. I've still got around 125gb of my 500gb hard drive left with it installed, i'd have thought that would be enough. I'm sure i've removed every last trace of omnisphere, and have removed the audio.cache so its off the audio unit manager too.
It might be worth mentioning i also have a 40gb east west play library installed. Could this clash with omnisphere, even though the particular project i'm talking about uses neither of these vsts?
I like to be able to work on the move, so would prefer not to use an external hard drive, if possible.... Would upgrading to a 1tb hard drive and boosting my ram to 8gb be a solution, or am i missing a trick or two here?
