I've been trying to use Reaper for a while now, and I just can't figure out how to play midis on it. I've been trying to create my own midi, but no sound comes out whenever I try to play the midi piano thing. (I downloaded a midi board called vmpk, it's very good. It works in programs like garageband, but not Reaper.) I've downloaded many VST's to try to get it to be able to play midis I'm trying to create, but it still doesn't work. Maybe because VST isn't really for mac, but... I'm not sure what to do.
