C) On KLM-369:
Feed the control voltages from the wheels into the multiplexer for A/D converting:
• Remove R16 (430k) and J4 (0 Ohm).
• Cut pcb trace to IC2/pin2 directly at pin2 (solder side).
• Cut pcb trace to IC2/pin4 directly at pin4 (solder side).
• Connect CN09/pin5 to IC2/pin4.
• Connect CN09/pin6 to IC2/pin2.
Note: These two connections require rather long wires. Route them on the component side of the pcb where you
can fix them below other components (e.g. a potentiometer).
D) On wheel assembly:
• Swap brown and orange wires of BEND pot.
• Disconnect two yellow wires from MOD pot. Leave them together and insulate the mending point with
shrinking tube.
• Disconnect red wire from BEND pot and connect to red wire of cable to J7 of MIDI pcb. Insulate with a piece
of shrinking tube.
• Disconnect blue wire from MOD pot and connect to middle pin of BEND pot. This blue wire will be quite short;
lengthen it with supplied piece of blue wire (40mm) and insulate with shrinking tube.
• Connect "upper" end of BEND pot to "upper" end of MOD pot. Use orange wire (140mm).
• Connect "lower" end of BEND pot to "lower" end of MOD pot. Use brown wire (140mm).
Refer to drawing no. PS 6M 00 05 005.
E) Mounting MIDI jacks:
These three DIN jacks are what you have waited for. Now you got them. The only thing you have to do is to drill
some holes into the back of your Polysix ...
To make this task easier I created a template which is part of the kit. Once more I recommend to unmount
everything from the top/back lid of the Polysix. Work is much safer then. Be sure that no filings are left in the
instrument!
(1) Unmount the control panel, knobs, rear jack assembly, power switch assembly, power supply pcb, power cable
hooks and take off the lid. Make notes or a sketch about connections and locations of components.
(2) Take off the cable clip on the inside of the lid. It is right on the same position where the MIDI jacks are going to
be.
(3) Take the template and fold it along the line.
(4) Hold the template against the lid: folded side on top of lid, MIDI jacks drawings on back side.
• Align left edge of template with edge of lid.
• Fix template in this position with adhesive tape.
• Take hammer and pointed tool and mark center points of holes to be drilled.
(5) Take off the template and drill the holes (good luck!).
• The big holes probably need some finish with the round file. Check size and shape with DIN jack and MIDI
cable.
• When you are satisfied with the shape of the holes paint the edges with black permanent marker.
(6) Before assembling the control panel with all the knobs, etc. make all modifications to KLM-369, KLM-370, and
KLM-371.
(7) Reassemble control panel.
