Below is audio of a piece I’m working on, called “Slow Blink.” The ring modulator on a synth comes in at 13 seconds. Schematic of the 4-diode design of a ring mod above. Has a sound like a broken bell. Without it this synth part sounds very clean, same as the synth that precedes it.
Ring modulators were originally hardware. I use a software version. But still, on a microscopic level, it’s probably using 2/3 of a transistor, 4 times, on my CPU. A transistor is 2 diodes with 3 leads, so you can use 2/3 of a transistor as a diode.
