MIDI INTERFACE KIT PARTSMIDI INTERFACE KIT PARTS

The supplied MIDI interface kit contains all necessary parts, materials, and detailed installation instructions. The kit contains:

1. MIDI interfac e bo ard

2. Bunched cables with MIDI socket

3. All necessary coupling elements (screws, nuts, washers)

4. Owner’s and Installation manuals in printed form

GENERAL INFORMATIONGENERAL INFORMATION

The installation of all interface components is very easy. If yo u follow the instruct ion from this manual there will be no major problems during the installation procedure. The cover of the instrument will not be markedly damaged during the installation. The physical appearance of the vintage instrument remains nearly th e same as before the installation. If n ecessary, th e in terface can be removed an d th e instrument restored back to original appearance. All original features of the Korg Poly-61 are kept. The instrument can be used the same way as before the retrofitting.

The following tools are necessary for the installation: Phillips screwdri ver, driller, drills 3,2 and 16 mm, smaller rasp, pliers, soldering iron (a low heat iron and soldering paste).

2222 MIDI INTERFACE INSTALLATION

The interface is connected to the keyboard switch matrix of the instrument in a parallel fashion (pic. 1). There are two versions of instrument’s main PCB board. Older is named KLM475, newer is named KLM-509. Although some little difference is between t hese boards, the interface i s applicable to both versions of instrument’s main board.

a) Unscrew the four screws from the bottom of the instrument (pic. 2.1-1) and the four screws on the front panel (pic. 2.1-2).

b) Carefully open the instrument - lift off the instrument’s front panel (pic. 2.1-3). Instrument’s main b oard (KLM475 / KLM-509) is located at left side inside the instrument.

It is better to place the MIDI-IN connector on the rear panel of the instrument for easier operation. It is



a) Flip the front cover over and return it to its original closed position on top of the synth.

b) Drill three ho les (one with 16 mm di ameter and two with 3,5 mm diameter) in the rear panel (see pic. 2.2-3). Work carefully so as to not drill the parts inside the instrument (pic. 2.2-4).

a) Solder the red cable (Vcc +5V - pin Nr. 1 of interface’s connector) to t he power distribution +5V on the KLM475 / KLM-509 board. The most suitable place is lead (pin) Nr. 14 of the IC3 (pic. 2.3-3).

b) Solder the blue cable (GROUND - pin Nr. 2 of interface’s connector) to the ground potential on the KLM-475 / KLM-509 board. The most suitable place is is lead (pin) Nr. 7 of the IC3 (pic. 2.3-4).

a) Detach bunched cables from CN29P and CN30D connectors on KLM-475 / KLM-509 board These cables lead from instrument’s keyboard (pic. 2.4-1).

b) Plug interface board onto CN29P and CN30D connectors on KLM-475 / KLM -509 board so that flat four-pin plug on interface’s board is to right (pic. 2.4-2).

c) Plug the connectors of the bunched cables from the keyboard onto the plugs on the interface’s board (pic.

2.4-3). Be careful, the connectors must not be rotated or exchanged. Locks of the connectors must be down. Bunched cables with black and white colored wires are left (CN29P connector) and bunched cables with yellow and white colored wires are right (CN30D connector).

d) Plug the flat 4-pin connector of newly installed bunched cables (from +5V, GND and MIDI-IN socket) to the flat connector on the MIDI-In interface board (pic. 2.4-4). The connector is shaped such that it cannot be connected the wrong way - there are locks on it.
