I just watched this video which demonstrates how versatile Korg's new Monotron synthesizer is.

This little synth was recently reviewed in the May 2010 Future Music Magazine (Issue 226) but this video looks at how it can filter other sounds, even guitar! I just recently purchased an analog synthesizer, the DSI Mopho, and one of the main features it sports is an audio in which can modulate and filter external audio signals, or create feedback within the synth.

Check out the video below to check out Korg's new product, and check back later this month to find a review on the Mopho synth.
