Yes i was the owner of one unit for a couple of months (January to February this year) and i was try to use it with Sonar X1.
I replace the unit with a Mackie MCU Pro due to the death of a fader (very poor quality) and the lack of compatibility with the Mackie emulation in Sonar (there are some trick to obtain a better emulation but you have to send hex command thru a midi loop).
I don't if it is still the same but i think yes.
