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

simply removed and the instrument restored back to original appearance.

All original circuits of the Korg Polysix remain without any modification. The instrument can be used the same

way as before the retrofitting.

installed if you don’t require transfer of MIDI data to another MIDI devices (THRU function) or reverse

communication of the interface with host system (OUT function). Nevertheless, having both MIDI input and

output is more convenient for an easy integration in a more advanced MIDI system.

There are more possible ways to install the MIDI-IN socket(s) if you do not want to mechanically damage the

panels of the instrument by drilling (see chapter 3.1).

Recommended method of the MIDI socket(s) montage is described below.

FOR MIDI SOCKETS DRILLING

a) The best solution is to mount the MIDI sockets to the power cord sub-panel on the rear panel of the

instrument, where the serial number plate is originally fixed (fig. 2.2.1). This solution is recommended, since

you can revert the instrument to its original appearance if you decide to remove the interface in the future.

b) Unscrew the serial number plate from the power cord sub-panel (fig. 2.2.1). Safely store the serial number

plate and two self-tapping screws for future usage

DIN sockets of the cables into the holes (fig. 2.2.3).

Both MIDI cables are identical and can be swapped.

b) Fix the DIN sockets to the panel using four self-

tapping screws from the interface accessory (fig.

RESET BUTTON AND INDICATION LED INSTALLATION

There are two control elements on the interface – reset button and indication LED. There are more possible

ways to install the button and the LED. The button and the LED need not be installed if you prefer to maintain

the vintage status of the instrument (i.e. if you don’t want to damage the instrument’s panel by drilling). Or you

can install only the reset button or only the indication LED (see chapter 3.2). Nevertheless having both of them

installed is more convenient for easier device control.
