Works great for me. I don't traditionally work with film scoring, but this plugin fits well in multiple genres of music. Some people seem to have experienced issues with it in the past, but this doesn't seem to be the case on my end.
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.
