As I already reply in your other post, I know 3 solution to externally control the CQ mixer via midi:
-connect an Ipad directly to the CQ. Some IOS app can mange the midi CC and Note ON/OFF with the CQ mixer (stage Traxx3). Have not tested with android.
-connect a BomeBox directly to the CQ. The Bome Box will receive midi message form any external midi device connected to it. BT widi is possible.
-use a PC between the CQ and the external midi controller. With this solution, you can do a lot of things by using third party free soft (MidiOx) for mapping, routing and a lot of other things.
BT midi is also possible here.
For example, I have set a simple 8 fader midi CC controller the send midi CC 100 to CC 107 to drive the CQ faders by mapping the values in MidiOx from CC to NRPN.
