Are VSTs only 32-bit?

Hello,

I recently had an experience where Vegas Movie Studio Platinum 15 crashed randomly during playback (again). I decided to open up my Task Manager and expand the MSP tree. When I expanded it I noticed a few things under the Movie Studio Platinum tree: Error Reporting client launcher, File I/O surrogate, TitlerStandalone.exe and Movie Studio Platinum. The last one was surprising - VST Server (32-bit). It's the only of the group that is listed as a 32-bit app.

I ask this question for a few reasons.

Is this correct that the VST interface for Movie Studio is 15, or is this just a secondary server for when 32-bit VSTs are available? I did a test and only added a 64-bit plugin, and it seemed the 32-bit was still there.

I ask as well, because if the program is only using 32-bit speeds for VST, I'd rather just use the 32-bit versions (if available) to prevent whatever conversations MSP is doing.

I'm pretty sure Vegas works with both flavors. To see if 64 bit improves performance, render the same project with both flavors, and compare.

32bit VST audio processing in a 64bit environment in all applications I've seen employs a "bridge" which generally lives in a separate process. So it's perfectly possible that the 32bit bridge may crash while the main application doesn't. Dont know if MS follows the same architecture but it's quite likely.

I'm running Vegas pro 18 suite and see VST Server (32 bit) when running when the application cashes. I have included FX BCC BEAITY Studio when Previewing the film. My computer runs more that 90% of the processes at 64 bit. Should VST Server be running at 32 bits? If not how do I get the 32 bit version off and a 64 bit version on.

Sorry I don't have your version to compare. Vegas Pro 14 loads the plugins from my 64 bit VST2 folders just fine. C:\\Program Files\ Common Files\VSTx

It may be that there are plugins that are not compatible that are causing the crashes when loading. Try eliminating various vendors' folders one at a time to see which one(s) may be causing your crashes.
