The 3dVCA (link) by Mystic Circuits takes a fundamental building block of synthesis (the VCA - Voltage Controlled Amplifier) and uses four of them behind an intuitive design to throw your sound sources into three-dimensional space. If you're thinking of Quadraphonic Sound from the 1970's - you're in the ballpark.

During my time beta-testing the 3dVCA I asked if I could help in any other capacity - thus, demonstration videos were put on the docket. I was pleased to get the opportunity to show some of the tips and tricks that I had discovered during my time exploring sound and exploiting the 3dVCA.
