i'm using the korg electribe as sequencer to send notes to the ipad, I would like to control the keys of the "yamaha dx layout", which are "playing" -soundless- now after performing "midi learn".
The DX7II hardware synth gives only sound by touching the virtual keys on the Ipad-mididesigner. -the layout works perfectly between DX7II and MIDIdesigner, there is only no "sounding" connection from other devices, and midi learn involves the same notes on all octaves, so may be this stil needs a specific midi channel which both devices agree on
