INTRODUCTION INTRODUCTIONINTRODUCTION
INTRODUCTION
Korg Polysix Keyboard MIDI Interface enables the integration of MIDI in your Polysix instrument. The
instrument's keyboard and arpeggiator speed can be controlled with this MIDI interface in parallel manner. The
interface only receives MIDI data so it has MIDI input only.

GENERAL INFORMATION
The installation of all interface components is very easy. If you follow the instruction 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 the same as
before the installation. If necessary, the interface can be removed and the instrument restored back to original
appearance. All original features of the Korg Polysix are kept. The instrument can be used the same way as
before the retrofitting.
The following tools are necessary for the installation: Phillips screwdriver, driller, drills 3,2 and 16 mm, smaller
rasp, pliers, soldering iron (a low heat iron and soldering paste).

There are three possible ways to install the MIDI-In jack.
 If you do not want to mechanically damage the rear panel of the instrument, take out the MIDI cable through
the slot on the left side of the keyboard (see pic. 2-1) and replace DIN socket with a cable type.

It is better to place the MIDI-In socket on the rear panel of the instrument for easier operation. It is necessary
to drill three holes in the instrument panel however. (see pic. 2-4). The MIDI-In connector can be installed
near the jack connectors (see pic. 2-2).

If you do not want to damage the instrument, it is possible to mount the MIDI-In connector on the serial
number plate on the power cord sub-panel instead. This solution is recommended, since you can revert the
instrument to its original appearance at any time. The MIDI-In connector installation procedure is as follows:
