Mini Moog for sale on Ebay

YouTube via lucio788. The auction link or number is not in the video description, so here's a search for Minimoog on Ebay. This post is interesting in that it shows the Mini's raw sound at a very base level. It gives you a sense of a starting point that you can compare to all other mini demos you've heard. This is why these posts go up along with the more "musical." For me it's about the sound and what you can do with it. Every synth brings something to the table. With that in mind here's another video from the same poster:
