The Euphonix / AVID MC Mix DAW control surface working here with FL Studio using the Mackie MCU protocol. All the software needed to make this work on Windows or Apple is feely available from the AVID website (You will need to sign up first). These controllers are no longer available new (at their "premium prices"). However, bargains are to be had on the secondhand market. By example the following is currently still live on Reverb at the time of this video: https://reverb.com/uk/item/63849037-euphonix-mc-mix (Fully working example for sale in good condition well for under £100!) That said, given the quality and functionality that is available with the MC Mix it is also not unusual to see these being advertised for sale on the second-hand market for upwards of £500!)
