From the project
Skiff-friendly SMD version of the Prok Eurorack Drum Modules.
Quadrants is a skiff-friendly SMD version of the Prok Drum Modules.
I love the Prok modules, but the 3-boards sandwich made them too deep to fit in my drum skiff. With this version, the depth is no longer about 40mm, but rather 30mm.
