Sorry, I tried " Settings > MIDI IN > On" but I got no Sound.
I testet my Soundsource with another device which worked.
So please take a look of my Arduino Sketch, especially the "noteOnStatus" Byte. The Author of
the book I got the Sketch from wrote its value is 144 (0x90) + 1-16 (MIDI Chanels). Maybe different
with the XW- G1 ?
