Since moving to Windows 10, if I try to use it in SONAR I get the box that says I have to install the latest version of Play. I've done so at least twice but it doesn't help. However, for some reason the standalone works fine.
It's been a while since I installed the latest Play, so I don't know if there was an option that I somehow overlooked that gives you the chance to choose VST as well as standalone. I'll be interested to hear what you find out.
It does include some great sounds that would be nice to have available.
