Are the Multi Mode controls meant to be active when Multi Mode is not enabled?
If you go into a patch with Multi Mode disabled (power switch 'off'), you can still change the zone controls e.g. transpose, detune, pan. That is, making a change affects the 'Single Mode'.
If Multi mode is then enabled, and then disabled, the zone changes are disabled, though visible. Touch a control again and it becomes active (when Multi Mode is in fact disabled). This behaviour was impossible in V2 because to see the controls, you needed to open the upper panel which enabled 'Multi-mode'.
Not sure how this is meant to be in V3 as it's not documented. It might be a bug, or might be a feature!
