Here's my version of the DIY Voice cards used with the incredible Pico System 3 modular synth made by Erica Synths.
This version adds space for 3 audio jacks and an open area for soldering on components to add extra functionality to the DIY Voice Cards, all while keeping the same patch points as the original cards. Ground and the tip signal from each jack are routed to the open area for ease of use.
Each Voice Card Includes 3 low profile jacks.
Example configurations will be available soon!
