Hi All! I'm a recent and in general satisfyied user of XW-P1, I must apologize if I start with askin for a troubleshooting here: To the point: Sometimes, after using some drawbar organ presets (for example the 0/2 Full Drawbar), and "managing" 2/3 times with the rotary botton (to change velocity in some part of the song i'm playing with my band), i note that the sound get out of tune, and if I switch to piano PCM, the sound remains out of tune. I'm in Tone Mode and the only thing I can make is to switch off the keyboard.. Someone can Help me? Thanx all ! I'm from Italy, sorry 4 my English
