Keyfax Hardware Phat Boy MIDI Performance Controller
Description
The Keyfax Phatboy (or Phat-Boy) is a compact, 14-knob hardware MIDI performance controller designed in the late 1990s by G-Media/Keyfax for real-time manipulation of synthesizer parameters. It was designed to add hands-on control over filter cutoffs, resonance, and envelopes for Roland GS, Yamaha XG, or software instruments. Handy dandy! Includes aftermarket power supply as shown.
