Well, I found the Verbose Install checkbox, checked it, but still couldn't get anything to happen. Then, after poking around some more, I saw that even the 64-bit version had installed some 32-bit VSTs -- not many, but some. And no VSTi's. So then it dawned on me that the install utility might give me a choice between 32-bit and 64-bit. Sure enough, it does. So I'm in the process of installing the 32-bit version from my original installation file. Here's hoping I can install all the other stuff that came with the 64-bit version -- or at least all the other 32-bit stuff. I'm most interested in a couple of 32-bit DXi's, really: TTS-1 and Roland's GrooveSynth.
I want to be able to run them within Band in a Box, which doesn't come with a good general MIDI synth. Which I found rather surprising, but there ya go. BiaB has, instead, Coyote "Forte" which works for a while initially, then stops working until you cough up $40 to get it running again. I never used it, so I don't know how good it is or whether or not it's worth the money. So I'd rather just use something I already own. Especially since I don't do much recording to .wav files within BiaB. I prefer to export my BiaB files (as MIDI) to Sonar where I can handle the instrumentation and mixdowns within it. So, being able to access TTS-1 and GrooveSynth within BiaB is more of a convenience -- having a better idea of what the files will sound like in Sonar than anything else.
Thanks for the help, y'a'll. I appreciate it!
