Hi everyone,


can anyone tell me how to sync the tempo of the MonoPoly arpeggiator
to the TR606?

Thanks
Luis

Hi, the TR606 has 2 trigger out minijacks. One associated with the Low
Tom and the other to the High Tom.

I tried connecting but I must have done something wrong because I
failed to sync them...

Any help?

thanks
Luis

The specifications are:

TRIGGER OUT x 2
   Mini-jack (HT, LT; +14V. 20 mSec pulse)

More info:


The TR-606 Rhythm Composer provides two independant, programmable
TRIGGER OUTs to allow interfacing with synthesizers or sequencers.
Each trigger is a positive 15 Volt, 20 millisecond pulse suitable for
activating either the Trigger or Gate inputs of most major brands of
equipment.

A synthesizer such as the Roland SH-09 may be gated to process its own
oscillators. By combining a mono synthesizer such as the SH-09 with a
sequencer such as one of the Roland CSQ digital sequencers, the TR-606
TRIGGERs will start and/or step the sequencer/synthesizer combination
for many programmed musical lines. The triggers may also be used to
control the rhythm and rate of the Arpeggio sections of the Roland
JUPITER polyphonic synthesizers.

The two TRIGGER OUTs correspond to rhythms programmed into the Low Tom
or High Tom positions, rhythms determined by the Track/Program
selector and programming. These instruments may be used simultaneously
with their TRIGGER OUT or programmed specifically to provide with
TRIGGER OUTPUT rhythms, silencing the instruments using the individual
INSTRUMENT MIX LEVEL (E) controls.

[The trigger outputs can also be used to trigger other analog
drumkits, such as those made by Simmons, Midwest Analog Products, etc.

Trigger-out606 to Arpeggiatorclock-in-MP will cause a late triggering of
the Arpeggiator. The Arpeggiator is a switched trigger in. You need some
adapter like

Hi All

Long time MP4 lover here..  turned it on today after a couple of
months storage and it's virtually silent, till I crank the headphones
loud and then....

when I play keys, I can hear at very low level noise like the "gate"
opening.

The VCA envelope controls shape the envelope of this low level noise.

If I twiddle the filter resonance, I can hear the noisy pot, but no
actual filter resonance.

If I twiddle the filter cutoff I hear nothing, it doesn't filter the
noise.

I can tell the VCO's are receiving trigger because their LED's light up.

*** SO *** looking a the block diagram, I guess I either have a
problem in the "mixer" (post VCO's pre VCF) or in the VCF itself???

Does anyone have an opinion on this??

Any suggestions graciously accepted,,,,,,

peace & sine waves
Simon

p.s. I never even knew there was an MP4 group....

Hi Simon

> The VCA envelope controls shape the envelope of this low level noise.
if you turn all four parameters of the VCA-Envelope fully
counter-clockwise. Playing a key you should hear a klick. -> if yes ->
VCA is good and the output socket is good.

Then set
VCA-Envelope to A=0, D=0, S=10, R=10
VCF-Envelope to A=0, D=0, S=0, R=0
VCF Cutoff = 5, Resoncance = 10, Envelope amount = 10(+5)
press a key several times, you should hear a fast resonance
"Zongggg"-like sound.
-> if not -> check the VCF-cutoff-modulation input socket. -> many other
problems tooo... ;-/ (see below)
-> if yes -> turn the cutoff frequency fully clockwise and turn up noise
volume: do you hear noise?
If no ->
If you are keen enough to open up the monopoly (ATTENTION: live
endangering electric power inside!) set the keyboard to hold, press four
notes (or unisono) and check the noise and VCOs signal at pin 1 of
connector 14 (the connector is at the right hand side of the VCO-pcb
between the volumes of VCO1 and VCO2). If you do not have an
socilloscope, the connect the output with an mixer and use the tip of
another cable, connected to the same mixer as signal search (don't turn
up the volume too loud, the signals might kill your
tweeters/headphones/ears).

If there is still nothing to hear I assume that the powersupply is
defect. If there is something to hear, either the cable between VCO pcb
and VCF pcb is broken, or the VCF chip SSM2044 is gone. Sometimes the
2044 is socketed, then you might check whether the chip is seated ok in
the socket. But this requires unmounting the pcb from the frontpanel,
which is not much fun.

Florian

Hi Florian, Thanks man!

I'm enjoying this, nerd that I am.

Indeed can't get the filter to self oscillate audibly as per your
instructions.

There is signal present at connector 14 pin 5 (I seem to have the "new
production" version).
Pin 1 of connector 14 is this great distorted version of the VCO's...
I'll resist the urge to go hotrodding the synth....

anyway...

Got the SSM2044 datasheet.

I have signal at Pin 1 (input) of the SSM2044 - though much lower in
level, though looking at the schematic theres a 33k resistor in line.

But no signal at Pin 3 (output) of the 2044 - totally dead - with the
controls set right.

I've reseated the 2044 and put a bit of deoxit on the pins and cable
connectors but no go.

Seems like the silence at 2044 pin 3 points to a dead filter chip, do
you think????

There are some 2044's on ebay, though some of the other numbers on the
top are different.  Do you think that matters????

Thanks heaps for your assistance Florian, really appreciated.

Now, still there is a little hope for the 2044. Check the voltage at pin
15 (offset) and pin 13. If it would be -15 Volts, then the VCF would
shut down completely and no other CV would help.

But in fact I fear a dead 2044 too.

No. Single SSMs are available from Senso (http://www.vintageplanet.nl/)
for around 17 Euros. The seller "technologytransplant" on ebay sells
good ones as sixpack for 55 Euros!

Hummm..  do you mean the voltage difference between those two pins?
Or the difference between each of them and ground??

thanks and thanks again

I mean difference between each of them and ground.

Florian

Hi Florian

I might of lost something in translation here.  This is what I
measuring...

I am referenceing the 2044 datasheet here:
http://www.synthdiy.com/show/?id=86

Setting the multimeter to DC and a range of 20v this is what I have

2044
pin 16 +V        = +15
pin 15 SIG IN-   = -0.09
pin 1 SIG IN+    = -0.06
pin 9  -V        = -15
pin 13 freq ctrl = -0.10 filter knob fully open
                  =  0.09 filter knob fully closed


Two things confuse me here...  the voltage for the signal seems very
low..  and also the Fc ctrl voltage seems low, and yet it responds
correctly to Fc knob, envelope etc.

Looking at the specs, the range is supposed to be 0.6 to 1.5.

However, I don't really know what I'm talking about here.  Do you know
???  :)))

thanks again
pot.

Hi Florian

Happy to report that my new SSM2044 arrived from vintage planet in the
Netherlands in record time.  Popped it in and all is well.  The synth
sounds "new".  Really happy.

Thanks heaps for your research and advice, much appreciated!!

Another MP4 lives to squelch another day....

when i turned on my korg MP4 last week i noticed that there was a
little smoke coming out of what appears to be the power supply(its
says on top 250v fuse)and it was dead. im not familiarized with all
this electronics so i was hoping i could find someone here that
understands something about VINTAGE GEAR or that could at least help
me identifiy the problems.

thanks

I think: If you are not familiar with electronics basically, then you
definitely should keep your hands of power supplies. Each mistake you
will do (and you will do mistakes) on a powersupply will kill the rest
of the synth at least - and assumingly it might kill also you.

If I misunderstood and you are only not familiar with analogue
electronics, then unplug all cables which connect the powersupply with
the other pcbs. Then switch on the synth measure first AC at the
transformer out, then DC at the large capacitors and then the regulated
DC at one of the connectors.

The service manual is available at several places. I host it on my site
too: http://fa.utfs.org/diy/korg_monopoly/index.html

EXPLICIT WARNING: if a single rail of the double rail power is missing
you will kill several rare integrated circuits like the SSM2044 VCF  and
the SSM2033 VCO. The VCOs are close to impossible to get today; the MP
is nearly worthless without them. If you think you are not technically
skilled enough then DON'T SWITCH THE MP ON again and bring it to a tech.

Florian

My MP is serial no: 371112

Is there any way of knowing based on serial no. if I have the updated
version of the MP with analog white noise circuitry?

I have one Doepfer MCV4 midi to cv box for sale.
Works fine with my Mono/Poly. The "learn" rubber button is missing,
but you can still press it with a pen or some other sharp object.

Prize= 65 euro, location: Finland
Contact: crc@...

Thanks Florian!

I have had this same problem for many years. One of my E key is
cracked, and i haven't found a replacement part anywhere. I even
mailed Korg about it, but they didn't answer. But now i finally found
one, so thanks a million!

My next project is to make new wooden side panels, and my m/p will be
like new ;)

I am absolutely in LOVE with the Korg Mono/Poly.  I've been looking
for one for about a year now.  The big issue is that the price has
become so inflated due to the Korg Legacy Collection and all these
collectors who sit on top of treasure troves of synths that just
collect dust while people who truly love them and would use them, like
myself, get left out in the dust.

So I am looking for a decent condition Mono/Poly.  I don't care if the
wood is messed up, or if the knobs are original, I just want one that
works.

I'm really excited that I found this place because you all know what
it's like and truly love this beast.  Also, you are all "real people,"
as it were.  We can hopefully work something out if you have one.

I can pay about $300-$400 up front and then we can work out a monthly
payment plan or something like that if that suits you.  I'm just
really ga-ga for this synth and I'm just so irritated by the inflated
prices and these hoarders.

Please email me at underpressure116 AT gmail DOT com

I don't check my yahoo email very often.

Thank you!

Mike Lucas

Hello Mike

it really sounds like you are under pressure.
I cannot confirm that the price of the MonoPoly inflated very much the
last ten years. I started looking for one in 1998, and back then they
costed here in Germany around 1000 to 1100 DeutschMarks (450-500 Euros).
Today you will get a good Monopoly for 600 Euros. I think this is not
too bad. And a MP is really worth that money. It is well built, I has no
   known problems like the Polysix with its battery, or the ProOne with
its keyboard. I am taking the MP since ten years on stage and it never
showed a single failure.

I can definitely recommend it and I can tell you it is worth saving your
money.

I absolutely agree, but I can't FIND a decent priced one anywhere.
Also, I am in the US, so 600 Euro is pretty ridiculous for me.  the
Mono/Poly cost about $400-500 USD in 1998 (about $250 in 1993!).

It's not that I don't want to pay or anything like that, it's just
that I cannot pay such a large amount at once.  It's simply not in the
cards right now.  And I have no credit, so I can't get any kind of a loan.

I'm definitely going to get one, it's just a matter of procuring it.
I was thinking about the Polysix, but I decided I really didn't want
to have to settle.  Especially when it's concerning such a large chunk
of change.

I'm hoping someone has one who is willing to let it go for a
reasonable price and is willing to work out some way of paying for it.
  Like I said, I can make payments monthly or something along those
lines, I just can't drop $800+ at one time while paying for school and
such.


PS: My screenname is named after the Queen song. ;-)

its price and demand. that is true with anything. i agree some are
over priced but for the most part all is fair. save your cash and hope
for the best. the synth is well worth it.

I can hardly believe this happened, what bad timing too. While playing
tonight my Mono/Poly went completely silent. Just was working fine and
then like the cable was unplugged, no sound. Everything behaves like
it's working, pressing a key in mono mode lights up all oscillators,
pressing to poly mode works and I can see the individual osc's lighting
up, but no sound, not even from the headphone jack.

I will start combing through the messages here and try to do some
troubleshooting in the meantime, but I'm hoping for some miracle to get
this up and running in three days before my bands next show. More than
half our set relies on the mono/poly, and I don't have any other
keyboard that even comes close to sounding like this. Maybe my casio vl-
tone, I could try that. :)

Anyways I really am in shock, all humor aside. If anyone has any
helpful info please shoot it my way. Thanks

That never happened here in Germany. The MonoPoly never went down that much.

An honest business never should think about credit. Buy what you can
afford. If you can't afford, then wait until your savings got that far.
(our world economy crisis is based on the fact, that so called
businessmen, think that credit is base for business. It is not.)

Ok, next investment will be a Roland Jupiter 8, which was used for that
recording ;-) (In the Musicland Studios I played once the one they used).

Hi,

Try setting all VCA Envelope potentiometers to lowest possible value,
same for all the VCO-Levels and the VCF cutoff frequency.
Turn up the Master volume very loud. If you hear a low "thumppp" or
maybe "click" from the VCA envelope, then assumingly the SSM2044 is gone.
If you don't hear the VCA envelope, then look for loose cabling. It is
the wire coming from the most right board with the VCF/VCA (Connector
CN16 pin 3) going to the most left board with LFOs and Bender (Connector
CN2 pin 3). You may check the signal at the VCF/VCA-Board at connector
CN16 (between EG-Intensity and KBD-Tracking pot) at pin 3.
Also the connector from the LFO-board to the socket board my need to be
reseated.

The only sound I seem to be able to get out of this, with it
completely cranked up, is when the noise potentiometer is turned up,
and the resonance and cutoff turned up. I can get a very faint hissy
noise when I'm playing, and if I turn the resonance and cutoff while
playing it changes the noise like you'd expect it to. Just almost
completely inaudible, this was all the way up and then fed into a
mixer with the gain all the way up.

I did try all the settings you recommended and did not hear
the "thwumppp" or the "click". I checked the wiring and it looked
fine, I reseated connectors.

I took the knobs off and backed the nuts off the pots, and took the
CN16 connector off and measured pin 3, but I didn't seem to be
getting anything. Should I be measuring it from the wire harness that
goes into it? That's where I measured it. I could be doing something
wrong. I did not check the CN2 pin 3, I was having difficulty finding
it and had to quickly come up with an alternate solution for
performing this wednesday night.

I'm still hoping though, do you have any other recommendations based
on what sound it's making, or by anything else I've written? Thanks
so much for your input and time. I was much happier with a working
mono/poly. I own a polysix as well, and these two synths have gone
down so many times on me before shows, and during shows. . . I really
ought to get the Korg Legacy 2007 and start performing with
emulation. I still want to write and record with the real thing, just
can't rely on them any longer it seems without becoming a tech!

This is good. It says the SSM2044 is not broken.

Basically I still think it is something not very troublesome; maybe the
low/mid/high-Levelswitch or the volume potentiometer is dirty or (in
worst case) broken. But both you could temporarily heal by bridging them.

You may try to measure (or listen with an cable) to the following
testpoints:
http://fa.utfs.org/diy/korg_monopoly/mp_13_klm_353_layout_testpoints.jpg
http://fa.utfs.org/diy/korg_monopoly/mp_14_klm_355_layout_testpoints.jpg
These show the pcbs from the solderside, so you don't have to remove the
pcbs from the front. The testpoints are marked yellow.
