I know that we can connect from iPad to Stage with Bluetooth dongles (Yamaha/quicco) or midi cable to control the Stage with Midi commands.
But wouldn't it be better to connect iPad to Stage directly with Wifi, and without extra hardware?
There is a protocol called Midi over Ethernet/Wifi (RTP). With this protocol we could have a network connection between iPad and Stage.
Bandhelper and Setlistmaker both support midi over Ethernet/Wifi and can send/receive Midi over network connection.
Kemper Team, please think about this feature, which minimizes hardware and simplifies the setup
