Text Box: 1. THE MIDI RIBBON CABLE IS NOW PRE-STRIPPED AT THE FACTORY. THEREFORE, YOU ONLY NEED TO SOLDER THE ENDS TO THE ALLEN KEYBOARD ARRAY CONNECTIONS SHOWN IN THIS MANUAL. PLEASE READ THE COMPLETE MANUAL BEFORE STARTING. BE CAREFUL TO AVOID STATIC DAMAGE. ALL CONNECTIONS SHOULD BE MADE WITH THE ORGAN TURNED OFF AND UNPLUGGED. 2. PLUG THE HARNESS INTO THE BACK OF THE MIDI BOARD AS SHOWN ON PAGE 3. 3. UNPLUG THE NECESSARY MIDI CHANNEL JUMPERS AS SHOWN ON THE BOARD “MIDI CHANNEL JUMPER CODE” TO SELECT WHICH MIDI CHANNEL YOU DESIRE PER DIVISION. IF USING SEPARATE MIDI SOUND GENERATORS FOR EACH DIVISION THEN YOU MAY AS WELL LEAVE ALL THE JUMPERS INSTALLED FOR CHANNEL 1. IF USING HAUPTWERK tm OR AN ALHBORN GALANTI ARCHIVE MODULE tm FOR EXAMPLE YOU WILL NEED TO SELECT THE CHANNELS THAT YOU SET UP IN THESE PRODUCTS. ALSO YOU WILL NEED EITHER A MIDI MERGER OR MIDI HUB TO COMBINE THE MIDI OUTPUT SIGNALS. WE WILL HAVE SUCH A DEVICE SHORTLY. NOTE THAT IF JUMPERS ARE CHANGED WHILE POWERED UP, THE MIDI CHANNEL WILL NOT CHANGE UNTIL THE ORGAN IS POWERED DOWN AND RE-STARTED. 4. BEING VERY CAREFUL TO DISCHARGE ANY STATIC, REMOVE THE KEYBOARD ARRAY BOARD (OR MDC BOARD) CONNECTORS FROM THE SIDE AND THE MOUNTING SCREWS. REMOVE THE ARRAY BOARD BY CAREFULLY UNPLUGGING IT FROM THE MOTHER BOARD OR REMOVE MDC MAIN BOARD. 5. USING THE PICTURES ON PAGE 5 AND 6 FOR STANDARD ARRAY BOARDS, SOLDER THE PREPARED HARNESS TO THE ARRAY BOARD. THIS BOARD IS COATED WITH A THIN COAT OF VARNISH SO APPLY SUFFICIENT HEAT TO ALLOW GOOD TINNING OF THE SOLDER LOCATIONS BEFORE SOLDERING THE WIRES TO THE BOARD. BE CAREFUL NOT TO LEAVE ANY SOLDER BALLS ON THE BOARD AND CHECK FOR SHORTED CONNECTIONS. FOR OTHER VERSIONS OF THE ARRAY BOARD, REFER TO LATER PAGES THAT WILL BE ADDED TO THIS INSTRUCTION BOOKLET AS NEEDED. 6. PLUG THE ARRAY BOARD BACK INTO THE MOTHER BOARD OR MDC BOARD AND USING SUPPLIED SPACERS AND SCREWS MOUNT THE MIDI BOARD ON TOP OF THE ARRAY BOARD. IF THE MIDI BOARD HITS ON THE ALLEN POTENTIOMETER(S), USE THE COLLAR WASHERS WITH THE SMALL CENTER THROUGH THE HOLE IN THE ALLEN KEYBOARD ARRAY. IN THE OTHER MOUNTING LOCATIONS USE THE ALLEN SCREWS. PLUG THE SIDE CONNECTORS BACK IN. MOUNT MDC MIDI BOARD AND LEVEL TRANSLATOR CLOSE TO MDC MAIN BOARD WITH SUPPLIED WOOD SCREWS AND SPACERS. 7.
