I have create a generic iOSs app (which also runs on Windows,Linux, MacOS, Android ), which can receive all MIDI events and generates all kind of MIDI events. I'm trying to configure this for Kemper (quite easy with the given MIDI doc), but I wondering (having my KPA not received yet, I can't try), If a routing as described in the title is possible:
KPA (MIDI out)->FCB1010(In)->FSV1010(MIDI merge Out)->iPad (MIDI In)->iPad(MIDI Out)->KPA (MIDI In). If such routing were possible, I can control the KPA directly from the FCB and also from the iPad. The iPad can visualize settings from KAP, receive special commands from FCB (looper cmds come to mind) and generate control events of any kind with a GUI.
I hope this is possible.
