I bought a APC mini MII for use with Quickshow. The buttons and sliders function but no lights. In MIDI Settings both input and output is set to APC mini MII. If I disconnect and reconnect the USB cable, one or more random button lights will usually flash briefly. I don't have a way to test the console other than QS. Before returning the console to Akai, I am hoping it is operator error. Thanks for any help.
