DIP switch 5:
This switch is used to select OMNI mode. OMNI Mode allows the JX42 to respond to Control and Program changes on
any MIDI channel (1-16). Setting the JX42 to a specific channel is particularly useful when linking multiple MIDI devices
as they can all be set to only respond to changes on their assigned channel.
Some MIDI equipment will default to OMNI mode when first switched on, so it is important to check configurations upon
power-up and re-select the channel on your device if necessary.

respond to MIDI commands.
