🎉 Ten Years of VolcaShare
Thursday, March 12, 2026
The VolcaShare code repository was unceremoniously created ten years ago, on March 12, 2016.
Since then, it's grown from an experimental Volca Bass patch database using WebMIDI into a
home for Volca Keys patches and browser-based emulators too.
To celebrate the ten years, I'm introducing something fun:
Mystery Patch,a daily challenge where you recreate a hidden synth patch by ear.
Thanks for popping in, checking out the patches, sharing your own, and playing with the emulators.
