Does it have to be MIDI?
Use TouchOSC on Android or iOS and you could be doing things like this
This is just an example. There are other presets (for matrix/mixer), and you can make your own ones too.
Of course, I will see all this in depth when I have time.I have a tablet (a PIPO of 10" with wifi and Android), and a motherboard with an integrated wifi device, with Windows 10. I suppose it is necessary to configure the drivers of the tablet itself and also the OSC communication.Instead of wifi, could use a USB cable between the tablet and the PC.More toys to play! 
Thank you and happy new year!!!
