This is a collection of videos concerning my large custom modular music synthesizer system and some of the other electronic music projects that I've done. I have been designing, building, and using custom electronic music gear since I was a teenager in the 1970s. More info is at synth.media.mit.edu, paradiso.media.mit.edu/synth.html, and much of the music I've made on my synth system is posted at joeparadiso.bandcamp.com. I sometimes make announcements on my synth's Twitter side @ModularSynth. I spend most of my waking hours as a professor at the MIT Media Lab, where the research team that I lead works on projects encompassing the Internet of Things, Human-Computer Interfaces (HCI), musical controllers & interactive media, large-scale low power distributed sensing, space and spacecraft applications, etc. Details here can be found at paradiso.media.mit.edu and beyond.
