Classic Unit: Evolution UC33 MIDI Controller This is a MIDI controller made by Evolution. I have confirmed that it starts up via USB connection and power supply from a Mac. The display and fader lights are also working without any problems. I used it with Ableton Live 12, and it recognized the device and functioned. I have not confirmed the operation of all the detailed functions. There are some scratches and dirt from use. Please understand this before purchasing. Included accessories: USB cable.
