I agree with Lee7. I have aquired Mixing station on my iPad and got to work on it. Is a learning curve but I got there including an Akai MidiMix gizmo hooked up via usb midi. I now have a physical version of what you seek. Was another learning curve again bit I have even got the button leds to illuminate when mutes on/off. I now have sub group Dcas working and corresponding group mutes along with the MidiMix buttons giving me Drum groupe vol and mute, backline group vol/mute external fx/voc processor/harmoniser, dj input and the 4 vocals on individual channel vol and mute. The MidiMix also has three rotaries you can program in tho I found the pan completely unusable, but you can use to adjust the FX sends or other CQ features that are available on the Mixing Station app. Very handy setup and will suffice for now and MS does not coast many pennies, about 6 pounds in UK
