Hello Dave, hello simplemindsfan,
welcome to the group! Though the mail traffic here is not a rush hour,
the group can provide great help. Please feel free to introduce yourself.
All the best!
Florian
Many thanks to Florian and Alan -Mono-poly is working again.
I just replaced the two 1A fuses (they were not rated 1.6A as Florian mentioned
-so maybe this i why they blew?)
Good to know you're all out their.

yes there are three screws along the rear underside. once inside you will see fuses on a board fixed to the bottom of the case and then another set of fuses on the rear panel. Don't forget to unplug the synth before opening up for safety.

Removed the four screws on front panel..but panel is loose but still fixed at rear when i try levering it upwards?
Are there any other fixings on rear of panel or underneath?
I'm being over cautious as i dont want to do damage.
Thanks

You have to unscrew the four srews at the boarders of the frontpanel and open up the frontpanel.

Have just switched everything on for a rainy afternoons knob twiddling to find
mono-poly is dead.
I suspect/hope fault is an internal fuse (in power supply?-UK version)
How do i access this easily to replace.

As I am a kind of collector of Roland Synths I can tell you, that the
Korg MonoPoly is very good complement for the Rolands. As well soundwise
as the voice structure it offers difference and completion to the Roland
family.
What kind of music do you make?

Hello Kraig and thank you very much for your advice, I will check those websites

Hello everyone!
I still am a proud owner of the mono/poly
but I have so many problems with it!
First, I bought from ebay and it arrived broken: the case and, more importantly, the volume knob and the MG one. I replaced the volume knob with a friend of mine as it is quite easy to do but to replace the MG is another game! So I haven't done it yet. By the way, the ebay seller didn't pack it securely enough but refused to take responsability for the breaking, and I never saw any money from the claim I filed to the UK postage.
That is why I cannot stress enough that it is important to be very careful buying your machine on ebay!!
On top of that, the synth proves now to have some false contact somewhere and it plays only sometimes!
I found a company that renews cases of synths but it is in the US. Is there is an equivalent in Europe?
I really like the sound of the synth (when it plays!) but I am a bit
discouraged and would like to know if you could advise me someone to bring it to that is not going to rip me off (I live in London).

Hi Florian, thanks for the welcome. I've had my mono/poly for about a week now
and am very impressed with it. I'm not sure I completely understand everything
about the "Effects" yet, but I'll get there.
As others have noted, odd numbers of keys latched in to the arppegiator in Poly
mode is good for passing a lot of time while tweaking parameters.
Does someone have the 8049 code (hexfile), or has someone attempted to
disassemble it? I wouldn't mind a mode to change the arppegiator up/down mode
to not repeat the high/low notes.
Also, anyone have better schematics? The VCO PCB is pretty hard to read in the
download files or other places on the net I've found.
-Dave

Welcome David to the Korg-MonoPoly-List.

It seems that light fixed the arpeggiator because it's working normally now after I assembled mono/poly back together. It might be some contact failure but where?
I tested the arpeggiator again and to me it seems that VCO's do play different notes.
I opened the mono/poly to check where the CV modification is connected.
From KLM-356C resistors R8, R9, R10 and R11 goes wires to the plugin socket pins.
From the another pin of the plugin sockets goes wires to KLM-354C CN12.
Arpeggiator used to work in Poly mode even CV modification was installed.

It is difficult to judge this without knowing details about the modifcation.
In fact the behaviour you are describing is like there would be a
trigger coming in to the Trigger input. This would override the muting
switches which select the individual VCOs (I use this sometimes
willingly to create chordtriggers which are not set with chordmemory,
but by hand and shall be held).

I don't know if it makes any difference to this problem but my mono/poly has been modified by the previous owner. It has individual CV inputs for the VCO's (no individual trig inputs, only CV). However, I don't have anything connected to the CV inputs.

Some questions for analysis:
Do the four VCOs play all the same note, or the notes you pressed as
arpeggio chord?
Does this happen with external arpeggio clock or with internal clock?
Is any cable connected to the trigger input (additionally to the clock in)?

I have a problem with mono/poly arpeggiator and I hope that someone could give me a hint what could be wrong.
When I set arpeggiator in latch mode and select Poly for key assing mode, oscilators won't play one by one. Instead, all the oscilators play at same time even the LED that indicates what oscilator is playing, lites one by one.
Great news Sophie. Heres to many more years of happy mono/poly modulation.

Hello acidolem,
well that is a wise decision to keep the Monopoly. Though the Crumar
Spirit is a neast on its own.

Do you need to replace the knob (the plastic thing, which sticks on the the potentiometer) or the potentiometer itself? If it is the potentiometer then: what is the failure with it? Usually cleaning the potentiometer solves the most problems.
If you really have to replace the potentiometer: it is a 10kOhm logarithmic potentiometer. Basically it is a potentiometer from the company ALPS, which is still available, but unfortunately you won't get the exact model with the mounting stands. You may try to find a similar potentiometer without the stands, and then put the inards of the new potentiometer into the housing of the old one.

Do you need to replace the knob (the plastic thing, which sticks on the
the potentiometer) or the potentiometer itself? If it is the
potentiometer then: what is the failure with it? Usually cleaning the
potentiometer solves the most problems.
If you really have to replace the potentiometer: it is a 10kOhm
logarithmic potentiometer. Basically it is a potentiometer from the
company ALPS, which is still available, but unfortunately you won't get
the exact model with the mounting stands. You may try to find a similar
potentiometer without the stands, and then put the inards of the new
potentiometer into the housing of the old one.
Kind regards, Florian
Hi everybody!
I need to replace the MG1 knob, do you know which potentiometer I should get?
Also, is there something I should be extra careful about when replacing it (I am
a beginner at opening synths)?
Many thanks to you for your time

Hi Michael
I wrote down the way, I am tuning the MonoPoly VCOs, and put it to my
website. See http://fa.utfs.org/diy/korg_monopoly/vco_adjustment.html
The basic trick is not to confuse the V/oct setting of the core
oscillator (which is VR403) with the V/oct settings of the octave switch
(VR401).
I hope it helps.
