PT does not support VSTi over 200 Mb.



Where did you get this from? I have a 380mb Studio Grand piano sample in my Emulator X program and I will also use multiple tracks of large samples in Sample Tank and they all play fine in PT but it takes a long time to load and that may be your problem. PT does not show you a progress bar when you open a SEQ that has a lot of midi instruments. If all someone is using for midi is the Roland VSC, that loads instantly because the samples are so small but any of the big name samplers have much bigger samples and those take some time. I have some songs with over 25 tracks of both midi and audio using several different synths and it can take a few minutes to load one of those. I try to render most of those midi tracks to audio as I'm working because of the load times but I will keep a copy of the original raw file in case I want to go back to the beginning for something. If you give up before it finishes loading and try to either close the program or go to another song, it will freeze and crash. Just wait until it loads everything even if it takes longer than you think it should. As much as I like the program, this is one of the clunkier things I don't like about it. I needs a progress bar when you first open a song and it needs a way to simply stop the loading if you realize you don't want that song.
It you already know this then I don't have an answer for you except to ask you to tell us your exact system setup, there may be something in the configuration settings.
