“Siel Mono – an Italian Monosynth from the early 80’s. Siel were in partnership with ARP and some of the Siel range were also badged as ARP such as the Quartet. I have had a couple of these Monos and this is by far the best example I have ever seen – see pictures for condition. There is no rust – which is common on these – and all button caps are present. All sliders, switches and lights work. This one has a rare volume pedal with it that fits the din style socket on the back. This one also still has the back legs to tilt it up – these are often missing on these synths. It can do a good impression of a Moog, fantastic basslines, lovely Pink Floyd horn synths and nasty leads. Still has original Owner’s Manual and Schematics which show it has been cared for. ” Link
Leider fehlt eine Potikappe und am rechten oberen Gehäuseeck
ist leider etwas der Lack abgegangen.
Der kleine Synth klingt “mördermäßig fett” und läßt jeden virtuellen
Synth und jedes PlugIn weit hinter sich!” Link
2 DCO (12 voices), 3 LFO, SSM (2044 filter/2056 vca) goodness.
This thing was torn down, cleaned, recapped, calibrated, key bed supports redone, bus bars from keys to vel sensor board resoldered, osc mod, every knob conditioned, and all connectors hot glued to ensure long term and stage durability.
I assure you this is the finest DK600 on the market right now. All the tech work was done by my tech, Duane R. Balvage. ”

“SIEL DK600 Analog Synthesizer Working Great and Sounds Awesome! See Pics & Desc! Up for sale today is my personal Siel DK600. I do a lot of buying and reselling but I have owned this one since around 1994! It was dead when I received it, but it turned out just to be the battery. Fortunately, this keyboard never suffered serious corrosion as I was able to replace the battery long before there were any major issues. I’ve had this keyboard in the closet for about 10 years and just don’t use it too much due to DAW plugins so I have reluctantly decided to let it go. The battery was once again dead, so I just put a fresh one in a few weeks ago. Also, I reprogrammed it using a sysex dump someone made on the Internet from an Opera 6 and it’s working great! Does everything work? Well, I do not know for sure. I know the tape interface which is used to save sounds never really seemed to restore the sounds correctly, but the sysex dump does! The controls for the DCO, LFO, etc are responsive and you can save and load sounds using the keyboard. However, there may be advanced functions I am missing. Anyone who is familiar with these keyboards know they are finicky and frankly, was not designed for travelling in my opinion. Since I have owned it, I moved to from Texas to Washington state, and back to Texas. Each time, I had to crack it open and reseat some of the connectors. When changing the battery, I attempted to clean them all as well as I could. What am I saying? It’s possible something could shift when I send it, but the worst case will be opening it up, and pushing all of the connectors tight. Hopefully, they are clean enough to make it. We package everything VERY well, and will take every precaution we can to keep it safe! ” Link
” SIEL DK600 Analog Synthesizer. Oscillators and keys and controls seem to be functional and it produces interesting synthesizer sounds, very clean condition, nothing obviously physically broken and all knobs and rockers vary the sound and appear to be functional. Was purchased by a friend and traded to me for my studio in exchange for other items and services. Not much interest in a synth since we record blues and rock.
It has two programs, 11 and 12 loaded, and entering other numbers does not produce sound. Contact me if you have specific questions I will try to answer. I am willing to do a phone or FaceTime to discuss the operation of the unit.” Link

“So I recently purchased this unit. The plug wiggled in the socket to the keyboard. It works sporadically when I wiggle the cord. When I get it just right everything works great. I did not put batteries in it (I didnt have any) but I assume because it’s a problem with the power cord input, it probably works fine with batteries. I did take the top off but don’t know how to fix it? The only other issue that I know of was that when I took the top off there are two broken plastic pieces that hold the screws. So in short it does work perfectly when you get the power cord adjusted right. It” pops” when the power cord is pushed so i assume it has a short. This will be shipped in its original styrofoam casing as pictured. It is sold as -is for repair, no returns. ” Link

“Siel DK-80, a rare hybrid digital / analog synthesizer from the mid 1980’s, with SSM chips. these can also be found in several vintage Korg synthesizers, and others, from the same era. so this is a great way of getting that lovely vintage Korg SSM sound but for a lot less money!
In good condition for its age and full working order. some slightly grubby marks to the keys – it was like this when I bought it, which could probably be removed with some sort of strong cleaner, but i’ve not bothered as it’s not that bad. The display is still clear and functioning as it should, although it’s difficult to get a decent picture of this in low light conditions as the numbers are bright-ish yellow.
There is a 2 Track Sequencer built in, Chord Memory, Hold Button, and a Pitch Bend Wheel. and apparently the filter resonance can be tweaked very easily on these synths, too, which might make it more desirable to some. I have not done this myself since owning it but can’t be sure it hadn’t already been done prior to my purchasing it, as it sounds really good to my ears as it is now. you basically just open it up and turn a pot slightly with a screwdriver, and that’s it. Please Google for more info on doing this if you’re interested, as I don’t know enough about it myself.
This synthesizer comes complete with its own (original) Siel power supply unit, as well as a very rare memory RAM card and the original Siel DK-80 owner’s manual. (Please see the pictures) ” Link

“Up for your consideration is a SIEL DK 80. This is a unique italian synth. The item condition is very good with only one small noticeable scratch on the face of the keyboard. No issues mechanically, additionally i’m not sure if these usually come w/wall wart supply but this has been converted to a regular supply that goes directly into the keyboard. Very unique sound.” Link
“This SIEL poly synth was 100% rebuilt and restored,and looks almost new! This ebayer I bought it from, earlier this year is a well known analog synth and sound/electronics engineer out of Arizona I believe. The synth has been 100% restored with better then original very high quality components and parts where needed, and all issues were addressed and this 6 voice poly synth with two oscillators per voice sounds great and functions 100%” Link
“Up for sale is a Siel Cruise Vintage String Synthesizer Mono Poly Keyboard Rare. This item is in good condition and please refer to the pics for more detail. There are 3 slider caps that are missing but that doesn’t change the functionality of the synthesizer. The monophonic portion of this synthesizer works when the keyboard is split and when it is being used as a full keyboard. The polyphonic portion of this synthesizer also works when the keyboard is split and for when using all the keys. All keys work and all the sliders work.” Link
” Working and sounds great! It takes 6 c batteries. No AC power cord! In the original box purchased from dacoit and Hansen music store Cincinnatti Ohio originally, email any questions! Thank you! KK” Link
“Up for sale is a Siel DK-80. It’s an Italian, 2 DCO synth, analog with digital controls, from 1985. Cosmetically rough condition because one of the plastic ends is cracked, and the door for the ram cartridge is loose. Its attached it just doesn’t hold itself open. Other than that the case has the normal scuffing, scratches etc, for a synth this age. The cracked side is not pretty but the fully functional. I did not program the sequencer as I didn’t have time to learn/get the manual. But all keys work, velocity works, all parameters adjust, midi is functional, all voices play, and it is in tune.” Link
“Up for your consideration is a vintage Siel DK 70 synthesizer keyboard. The unit powers on with 8 C batteries but I cannot get it to function beyond that. I have no knowledge on how to program or work this. AC adapter not included. Overall good, clean condition with some minor scratches and scuffs. The key card is taped onto the panel. This could be a great keyboard for someone who knows how to get her going. Sold as-is. Comes from a smoke free home.” Link
All the keys are working.
The switches are complete, and working without pops and cracks.” Link
“Up for grabs is a Siel DK80 synthesizer. Extras include a very rugged travel case, and a Siel Ram Pack. ( I was never able to get the RP to work-possibly a battery issue?, but maybe someone better qualified than me can get it to work) Includes the original power supply and manual. I’m a guitar player and not a keyboardist, but as far as I can tell everything works as it should. MIDI works well-I had it hooked up to another synth. I never tried to program anything with it and just used the sounds that it came with. Very retro sounding KB. Lots of great sounds already, but I’m sure it is capable of much more than I’m aware of. Google Siel DK80 to find it’s specs. I’m not using it anymore, so it’s time for it to find a new home. It’s in great shape for it’s vintage. The road case has a few minor dings, but is solid as can be. Hinges and latches all work as they should. This will make a nice addition to your collection as it did mine. Thanks for looking. ” Link
“Quick sale required on this lovely Siel Mono synthesizer. It produces a fat, Moog type bass, has a great noise generator, and the resonance really screams! It comes with a manual printed off the internet. The main volume and resonance sliders need attention as they are worn and tend to cut out when pushed right to the top, but with some minor work and some electrical cleaner, this vintage piece of kit should come up a treat. One slider cap has been replaced. ” Link
Please note that powering up this unit requires the DK80 power supply with the 5 pin jack. You will not be able to use it without the power the DK80 power supply.
The expander is in beautiful shape and seems almost like it was never used. Please refer to photos for condition. ” Link
“SIEL CRUISE IN VERY GOOD CONDITION.
ONLY 2 FLAWS: ONE KEY DOES NOT TRIGGER ANY SOUND AND THE GUITAR PRESET IS AT A LOW VOLUME LEVEL.
I WILL SHIP WITH THE ORIGINAL CASE (NOT IN GOOD CONDITION) FOR FREE.” Link
