Bought this (cheap!) as part of a Sonovox package with Eighty-Eight piano and the Orchestral Companion Brass, Strings and Woodwinds. I love the other instruments and would really like to love this one, but unfortunately, it crashes (and takes down your DAW) instantly upon being sent a MIDI note. You can play the sounds using the tiny-and-less-than-useful interface graphical buttons. Oh, well... maybe it'll get updated? Not holding my breath.
You need to click on the "Learn" button first. Then you can send MIDI notes normally. It's a workaround I found on a forum. The chances of these plug-ins ever being updated are zero in my opinion. Still, for the money the sounds are great.
