If you like a well demo'd synth, Dr Mix is your guy. An encyclopedic knowledge of famous riffs played on the world's best known synths, and entertaining with it. (How I hate that guy!)
Embedded below is his Korg M1 play through, but he's also done a Roland D50, and a Juno 106, which are also well worth a watch. Plus plenty of other electronic music related vids.
This time we show the venerable Korg M1 Synthesizer and play some of its most famous presets. We can play this and many other synths on your music.
