The recent release of the Moog Model 15 Modular Synthesizer app made me miss the days of music class at LaGuardia high school. I remember one of my music theory classes having like 10 of these synthesizers available for us to play. At the time, I wasn't hugely interested in it, but looking back at it all now, I am forever grateful that I was at least given the opportunity to freeplay on these guys. Thanks Mr. Fogel, you really were one of my favorite teachers.
Here's a bunch of videos of these synths.
First is a video of Craig Leon talking about how he remade classical music on the Moog synthesizer for an entire album called Bach to Moog.
