It crashes Sonar X1 Producer Expanded with the most interesting--yet utterly useless--error message I've ever seen. Unfortunately, it did this every time I tried to use it, so I had to remove it.
It installs as a VST "effect", even though you'd be adding anything you download as an "instrument" track, ostensibly. But since it doesn't actually work, it's hard to say exactly how you're supposed to use it..
There's nothing in the way of instructions on how to use it, other than to install it to your VST host. The developer's Website offers nothing, either.
It seems like a cool idea. Maybe someone else will have better luck with it.
