I can't seem to get the Harmony Momentary (Harm Moment) to work correctly with my Switch-3. What am I doing wrong?
First of all, please make sure that your Switch-3 is connected with a TRS cable and then check that Harm Moment is set to ON on the Switch-3 page of the Setup menu. Also in this page the Harmony effect needs to be assigned to one of the three Switches.
Here is the important part! On any given preset, you must make sure that on the Harmony page within the Setup menu, that the selection Control in the bottom left-hand corner of the screen is set to OFF. Only then will the momentary harmony function work correctly from your Switch-3.
