There are two fuses with 1.6 Ampere slow blow each on the low voltage
side of the transformer. They are located at the power supply pcb, which
is located at the rear bottom of the synth.

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.
Many thanks

Hi, I'm parting out a keyboard assembly.  If anybody needs replacement keys,
please contact me off list.

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?

Florian

I have a parted out Polysix, if anyone needs any part (many are the same as
MonoPoly) please email me.

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

Best
Sophie

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).

many thanks in advance for your time in the matter
and thanks for this group

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.

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).

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)?

Florian

Thank you very much for your help, Florian and Alan, I found the potentiometer
on ebay, it is a used one.

Sophie

http://myworld.ebay.co.uk/organparts&ssPageName=STRK:MEFSX:SELLERIDon ebay he
often has the correct original pots.  You shouldn't need to replace the plastic
cap but its always good to have a spare or two in reserve.

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.

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

cheers
Sophie

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.

Florian

potentiometer i should adjust to get the keytrack of OSC 4 corrected.
