Hi, I did not understand if Alan meant that I can use the TL072CP or not or I have to buy another chips which are only TL072 and not CP. I will open the...
Sorry to correct my previous post. I mean where is the board KLM-398 to my board ? According the picture I sent in my first post, it is not where it should be....
Yes you can use TL072CP don't worry about the CP the number is right. Not sure what you mean by where is KLM-398. Its right here in your picture. The small...
A ha I see what you mean now. Thought the first picture was your monopoly. obviously not. Very interesting nto seen that before. I may have to pass this...
Hello the old version of the MonoPoly did not have the KLM398. Also I don't understand what for you are looking at the 398. You have to change the IC10 on...
What is the thermal adhesive that Korg used on the resistors that go across the VCOs in the mono-poly? I imagine I could just use the same thermal compound...
Hi, Ok, I understood that I have the older revision of Monopoly, that;s why I do not have the KLM398. Today I opened the case as promised, with care. You can...
Hello ... Yes. There are two, but the one which affects VCO4 is under the second bentover capacitor (counted from the bottom of the circle). ... There is a...
Hi Florian, Your information is valuable !!!!!!!! Thank you very very much. I will follow your steps tomorrow morning, as I think you have almost explained me...
Hi, Today I reopened the case and boards but I couldn't touch the TL chips. I am afraid that my skills are not too good to proceed unsolder it, without causing...
Hello ... Some question come to my mind now (I might have asked them before): How does the portamento for VCO4 behave if you put the Synth to Unisono mode? ...
... Only for VCO4: In all mono modes, Chord and Unison, portamento is set to 0: pressing C: no portamento pressing C again after few seconds: no portamento ...
Hello ... Repeating a note never will produce portamento. Portamento slows down note changes. Very interesting in this listing is that there is no portamento...
... There is always a portamento to all directions, when portamento pot is set to 0 and when it is set to max. ... Portamento Pot is ON/OFF same behavior: it...
Hello ... AAARRRGH!!!! You are mixing up things. Do not use a sequencer!!!! Stay with one thing if you try to track down a failure. Never change two variables...
Florian, I did not use a sequencer. I meant I followed the sequence from 16 to 8 then to 4 then to 2... etc Step 1: I turned on the Monopoly, meanwhile I am...
Hi ... ok, I had a look at that: Both groups of additional parts appearently are NOT modifications, but they seem to be the standard wiring of the very first...
Hi, Thank you for your time and effort to do something like that. ... I thought it was a relative midi connector which never implemented :-) Now, about the...
Hi ... The working principle of the portamento circuit is very simple. There is an capacitor between ground and the control voltage line from the keyboard for...
Hi, I understood. ... I just re-opened the synth and checked all lines of the pot which correspond to the solder joints to the motherboard. No corruptions...
Check this photo: http://tinypic.com/r/34sfsb9/5 I have enclosed which solder joint on Portamento pot corresponds with what. There are four pairs and I assume...
Hi ... ok, now turn the potentiometer fully counterclock wise and in each layer of the potentiometer measures the resistance between the left contact and the...
Hi, All four measures seem to be the same: http://tinypic.com/r/9r0nxv/5 http://tinypic.com/r/2j272gk/5 http://tinypic.com/r/v3zibo/5 Sorry the fourth picture...
Hi, No problem Florian, you already did a lot to help me find what causes the issue. It seems that I have to give it for service in order to be checked...
Hi, I attempted the sample and hold mod. Installed it into all the right locations, etc. The board is getting the right power. But, The sample and hold does...
So I did get my sample and hold mod to work. I had to attach different parts of the mod wheel pot to the MG1 or sample and hold switch. Maybe it was because I...
