I have organized the modular synthesis videos that I have created and uploaded to YouTube. These video show the VCV Rack synthesizer screen as it models a hardware synthesizer to play what I have built. VCV Rack is a software model of hardware called Eurorack Synthesizer. If I had all of the hardware that you see in those videos, it would cost thousands of dollars.
With a modular synthesizer, the musician puts together discrete modules that might all be built into a more normal synthesizer that you see on stage with musicians.
Having this software model, I have spent months learning it. Interestingly, most of these pieces just took a few hours or days to build once I knew the modules and had the idea.
Here is the playlist. Each piece is very different from the next.
