The Effigy Labs Control Pedal is a rather strange thing to look at... The pedal uses their patented sensors together with a T-balanced foot mechanism. The pedal allows for left, right, and forward sensor control over almost any MIDI parameter.
The Effigy Control Pedal is equipped with a MIDI jack and USB port to allow direct control of your MIDI keyboards and processors or your favorite music applications.
Re-mapping controllers at the computer or keyboard makes the three quick access modes a versatile way to use its MIDI functions.
