Faderfox EC4 MIDI Controller

The EC4 is Faderfox's dedicated encoder controller — sixteen endless rotary encoders with LED rings arranged in a 4x4 grid, each capable of transmitting up to four MIDI messages simultaneously via push, turn, shift-push, and shift-turn functions. That gives you up to 64 independent MIDI assignments from a controller that fits in a jacket pocket. Four group buttons switch between encoder banks for deep parameter mapping across DAWs, modular setups, and software instruments, and the high-resolution encoder mode delivers 14-bit MIDI output for smooth, zipper-free parameter sweeps on supported software. The polycarbonate housing is thicker than it looks — Faderfox builds these in Germany to a standard that outlasts most controllers twice the size. USB MIDI and 5-pin DIN MIDI out cover both computer-based and standalone hardware setups. For anyone building a compact, deep, hands-on control surface, the EC4 is a well-considered tool.
This unit is in good condition and fully functional throughout. Cosmetic wear consistent with regular use. Photos show the condition accurately.
