Hi David, thanks for your answer Ok, I have understood, that the midi-designer can control the parameter in the solo-synth-mode. But I have thought, that when I join a sound on the xw, the parameter of this sound (osc, lfo, ...) would transmit from the xw to the ipad and would shown in midi-designer This is not so, right? Greetings and a good 2015 Holger
