Set Expression/Insight MIDI Out connector to MIDI Thru:
Step 1: Turn off the facepanel.
Step 2: Open the facepanel (see Open the Facepanel, page 219 ).
Step 3: Locate the jumper at location J5 (J8 for Insight 2x) on the circuit board in the lid
of the facepanel. With the lid in an upright position, the jumper should be near the
lower right corner of the circuit board. It may be under a ribbon cable. If so,
disconnect the ribbon cable to access the jumper.
N o t e :
This ribbon cable connects the facepanel circuit board to the main CPU.
Step 4: The jumper at location J5 (J8 for Insight 2x) should be installed on the pair of pins
labeled 1A for MIDI Out to be active. To use the MIDI Out connector as a MIDI
Thru connector, move the jumper to the pins labeled 2 (B for Insight 2x).
Step 5: If you disconnected a ribbon cable to access the jumper, reconnect it before
closing the facepanel.
Step 6: Close the facepanel and test for proper operation.
On older Expression/Concept/Insight 2x facepanels with keyswitch power switches, the
jumper locations are slightly different.
Set older Expression/Concept/Insight 2x MIDI Out connector to MIDI Thru:
Step 1: Locate the jumper at location J207 on the circuit board in the lid of the facepanel.
With the lid in an upright position, the jumper should be near the lower right
corner of the circuit board, just below the level wheel. It may be under a ribbon
cable. If so, disconnect the ribbon cable to access the jumper.
N o t e :
This ribbon cable connects the facepanel circuit board to the main CPU.
Step 2: The jumper at location J207 should be installed on the pair of pins labeled 1 for
MIDI Out to be active. To use the MIDI Out connector as a MIDI Thru connector,
move the jumper to the pins labeled 2.
Step 3: If you disconnected a ribbon cable to access the jumper, reconnect it before
closing the facepanel.
Step 4: Close the facepanel and test for proper operation.
