Its only about 6 months old. My vst programs im running are Edirol Superquartet, and Edirol Vsc. Is there any way to fix this problem?< The "system overload" alert usually means that either your audio driver isn't really optimised for "real-time" DAW use and isn't responding quickly enough, or that it has other problems that prevent it working properly with logic, or that you are asking logic to run too much stuff (too much processing, to many software instruments, etc) at the same time. Or a combination of the above. As the other guy said, we need to know what your soundcard is, and which drivers you are using. Some soundcards originally shipped with drivers that were only really tested for playing back game audio, and using them in logic would cause a freeze and throw up that dreaded "overload" error message. If you have an Audigy1, for instance, trying to use the drivers on the original CD won't work, you'd need to get the updated ones from the Creative website or some other third party set of drivers. The good news is that if this is your problem, and if your audio hardware is a few years old, chances are they'll have ironed out the bugs and problems by now in the latest driver release. On the other hand, if the problem disappears when you delete one or both VSTs from your song's tracks, perhaps its simply that the EdiRol software is putting too much of a demand on your system ... Do you have multiple instances of those VSTs set up in the song? Remember, they might be using up valuable system resources by just sitting there on standby even when they aren't playing. This might be more of an issue with seriously multitimbral softinstruments like the EdiRol range than with the more common single-instrument VST instruments, since each EdiRol instance can represent a whole stack of instruments, and it might be kinda assumed by their designers (from their all-in-one approach) that the user is therefore less likely to be running multiple VST's. ============= SO: .... If the problem disappears in an empty song with no softinstruments, it's likely to be your soundcard or driver or soundcard setup. Try this first. .... but if the problem only appears when you start adding one or two or more Edirol instruments to your empty song, then you need to find some sort of specialised forum where people can advise on the specifics of those particular software apps and how best to set them up, alone and in combination. For instance, if you are using Super Quartet v1.02, there's a v1.5 update available on EdiRol's website that give you a new option called "light load mode" that simplifies some of the VST's internal processing so that it puts less of a load on the computer. That might help, or there might be some other tricks or hints to using those instruments that only another user would be likely to know about, and which would only be likely to crop up on a discussion group dedicated to that softsynth range. But check the soundcard/driver stuff first, that's a very common problem
