Fran Carango: balance is not a matter -- style or voices was aloud, but is was silence with both.

freddynl: midi is in "local on" -- if not it was not chord recognition worked.

Phantom75: yes, you are really from Roland here in SZ!!! I am not touched sustain switch for months (since mid january), but (as I can guess) my 2year and 10 month old son changed socket from sustain switch to expression pedal. I return back this wrong connection -- and all go work fine! Thank you so much! If you indeed work at Roland: there are simple give warnings on a screen in such situation in next OS version.
