The FC-9 is a heavy duty in-line volume pedal for one, or two keyboards (or any other line inputs). Features two 1/4" input jacks and two 1/4" output jacks to control the audio volume of two separate instruments.

This is not a MIDI controller, but Output 2 can be switched to function as a CV controller instead of an audio volume controller, and can be plugged into the volume or modulation jack of most synthesizers. For your convenience, the FC-9 also includes a MIN VOL control knob, increasing the minimum volume as you turn the knob, allowing you to narrow the volume range.
