Everyone seems to do their sound demos in mono so I decided to hook up a pair of stereo mics and see if it was worth the trouble. Long story short: eh, probably not but it's been fun to mess with. Anyway, here's a test recording of a mystery keyboard to see if you folks can identify it by sound alone. It's nothing very rare but it is vintage, that's the only hint you get. I recommend headphones to experience the small amount of stereo septation that is present! I uploaded it to OneDrive since audio files aren't allowed as attachments.
