The Meatsphere I hate that name. Then again it’s a play on the name Meatball. The Meatball, if you are not familiar, is an envelope filter based on the Mutron III. The Meatball was made by Lovetone who went out of business in the early to mid 2000s. Lovetone seems to be coming back. Hard…
Here’s an idea for a ring modulator. I used a 3080 for the balanced modulator from the Ring-Modu-Matic. I used an envelope, from the Meatball, to control the carrier frequency. This is untested. The controlling the FET to turn on the carrier is going to be a challenge.
