Hi Ben, Another LAW user reported here a while back that using a P4 with hyperthreading and with the use of the I/O plugin trick, many more instances of Platinum Verb will run with Hyperthreading on that with it off. This resembles the behaviour of Logic 5.x on dual processor G4 Macs where the I/O plugin trick allows many more plugins to run because they run on the second processor when the I/O plugin has been inserted on the channel they are on. The above indicates that LAW is indeed a threaded app on its own and it does support hyperthreading to some degree. On another subject - can anyone report on whether you can run Logic Win Platinum 5.5.1 successfully with 2 GB of RAM? Are there problems beyond the error when merging audio files (which was fixed for me by the VCACHE changes)? I would like to use the extra RAM for EXS24 and third party plugs which load a lot of samples in RAM. Regards, Murray

The merging bug returned and we couldn't get rid of it no matter what VCACHE setting was used. It could have been machine specific but I doubt it. Here's the kicker, merging worked on his machine until he loaded large sample sets. I'm guessing that Logic makes use of the same memory (free mem below 512Meg) to load samples as well as other operations like merging audio files. Once that memory is used up, whether it be with the VACHE, samples or programs... Logic begins to run into low memory situations. It's "old" programming that probably worked fine in the days of Win95 and Win98. Howard
