Keyboard #1 is transmitting digital data via MIDI OUT jack.

Keyboard #2 is receiving this digital data via MIDI IN jack.

Keyboard #2 is also passing THRU Data received via MIDI IN from Keyboard #1 unchanged to Sound Module #3

Sound Module #3 is receiving the digital data transmitted from Keyboard #1 MIDI OUT jack via the Keyboard #2 MIDI THRU jack.

The LH-1 will normally be placed in the #1 position as the primary controller, but could be connected into other positions.

LH-1 Example:

Using the above graphic for explanation:

The graphic shows Keyboard #1 as the primary controlling instrument.

When the LH-1 is in position #1, its MIDI played key data will be transmitted to instrument #2, which also passes THRU unchanged to #3. You could select sounds in #2 and #3 and hear these sounds while playing the LH-1.

Selecting MIDI Local Off in LH-1 System Mode would allow you to hear only instrument #2 and #3.
