I have Direct Wave, and it makes no sound in Notion. It makes sound in FL Studio, but I prefer Notion for it's greater simplicity (though it would be great to be able to use additional soundfonts from FL Studio). It opens just fine and is available in my VST plugin manager. But there's no sound when I try to use it.
If anyone has an answer, I don't mind if you get technical. I know my way around computers reasonably well.
