“Listing is for both synths—if you want just one send a message I may consider it.
Picked these up and they were supposed to be both working. At first I thought this might be true because the first one I tried does make sound normally, but as I tested them more I realized they are both broken. NOTE: I had these in storage for a bit and when taken out I noticed they still have a smell of smoke from previous owner. I’ll try to wipe them down but keep in mind it may take more than that to get rid of the smell. Also—they both share a weird custom power supply which seems to work fine but uses what appears to be a midi cable connection?? Very mysterious but it works.
Synth 1: all controls and buttons work and makes noise Except the second DCO does not work, the noise control also doesn’t work, but interestingly some presets will have noise added but it’s usually too loud, and just sounds a bit weird or sloppy. As is can get many tones out of it, but only 1 DCO per voice. Filters and stuff work with no issue.
Synth 2: turns on and seems to respond to all buttons on the screen but can’t hear any noise at all. Also has two keys which stick up as seen in pictures.
Cool sounding synth, I wish they worked but as is I don’t know what to do with them.”

“Up for sale is a 1984 Siel Expander analog synthesizer module, in rough but mostly working condition (details to follow). This is the module/tabletop version of the DK-600.
The machine was not working when I purchased it, so I replaced the fuse and fuse holder on the back of the unit. I also had to add a wire on CPU board to get the envelopes to fire, as one of the traces had been corroded by a prior battery leak. I also replaced the old RAM battery with 3x AA lithium batteries I mounted to the bottom of the unit on the inside.
It has played well over the past four years after I was able to get it working, but with the amount of old corrosion I found and had to clean on the CPU board, I cannot guarantee how long it will continue to work long-term and I will therefore list it as “for repair”. In addition, I never used the pedal, tape, or MIDI THRU ports, so I cannot attest to the functionality of those items. Please buy at your own risk!” Click here to visit listing on eBay

“Collection only please due to weight, and I haven’t got a box that is be able to fit it in.
Never gigged with only home studio use.
Please note this is working fully as a midi controller, but currently has no sound, it looks like it could just need a new battery after some Internet searches, but not that technical so don’t know.
Siel DK-80 Vintage Synthesiser 1985 Very Rare!. Low serial number of 3780, so was one of the first to be produced of this synth.
It’s 12 note polyphonic, velocity sensitive, the modulation wheel doubles as the pitch bend with a button press, you can reprogram some of the presets, I can’t remember how many possibly 10. If you know the Ex80 the expander version it’s basically 2 of them bolted together with a lovely feeling keyboard.
Works fully as a midi controller, with hardly any marks, especially since I bought it in 1985! That was the year it was made as well.
So there’s a few scratches underneath and a few of the screws could do with tightening and glueing, main problem is it has no sounds, apparently that could just be the battery, as I’ve had it done before and it worked, but I believe it’s soldered in. Quick fix if it’s just that and can do it.
Broken key as in photo – looked at replacing it, as a key on here is about a fiver, but as I’ve broken my shoulder just haven’t got the strength to do it, as its a heavy keyboard.
Oh the cartridge slot has had a spot of superglue on it to keep it closed as the spring needs repositioning or replacing, not a problem really if you haven’t got a cartridge.
Comes with case, black and red, new USB cable and PSU as apparently not many have them anymore.” Click here to visit listing on eBay

“Used Siel DK 80 FM Synthesizer. From 1985. Very similar to the DX-7 Yamaha. I used this for a few years and it always worked well. Pulled it out of storage yesterday (a temperature controlled bedroom in my parents house) to test before selling and it doesn’t seem to work anymore, however. The unit makes somewhat loud (relative to the sound of the synth sound) buzzing sound, or the synth level seems quite low. Also, the synth doesn’t seem to want to change programs but honestly maybe that is simply because I can’t quite remember what to do to make that happen!” Click here to search for synths on eBay

” Siel EX 80 Synthesizer with PS 80 Power Supply and Case – Great Condition.
So, what’s this?! The Italian company Siel released their DK80 synth keyboard in 1985, which was a 12 voice analogue bi-timbric (2 sounds at once) synth. The Expander 80 was also released at the same time (costing only £399, the cheapest instrument in it’s class by a long way) being essentially (but not just) half a DK80 – 8 voice polyphonic and one sound at a time. Originally the Expander 80 was not supplied with a power supply, as the DK80 one was designed to drive the pair (Siel expected the DK80 owner to be the typical owner of the Expander 80). The Expander 80 still retained the 300 event two track sequencer, although both tracks have to play the same sound. Similarities to the Korg EX800 cannot be ignored, especially as the voice architecture and front panel layout do have similarities. The Korg EX800 was released a year earlier in 1984, so the Siel Expander 80 definitely followed it. Internally, they share no common electronics – so it’s no surprise they sound different.
Of course, people realised pretty quickly that if you didn’t need yet another set of keys, the EX 80 was actually probably a much more useful and versatile instrument, as part of a wider rig.
Over time, this has become a) rare as hens teeth and b) quite sought after as a seriously quirky (and with some tweaking, surprisingly aggressive) monosynth, with a real analogue sound, digital control, and a lot of character. The other major issue with these is the ludicrous power supply which is very hard to find indeed, and which have started selling for silly money on their own (and which can power both a DK 80 and EX 80 at the same time, if needed – two outputs). Luckily, this listing includes an original power supply, so no trouble in store with that.
I’m also selling this with the case it’s currently living in – it fits it well (minus power supply, which could handily double as a boat anchor) – it’s a good solid well-padded case, so that’s a nice bonus.” Click here to search for synths on eBay

The Orchestra is a 4-part orchestral synthesizer from the classic Italian synth company, Siel (later bought by ARP and relabelled the Quartet). The Orchestra has 4 presets: Brass, Strings, Organ and Piano.
The 4 tone color families can be played individually or two can be simultaneously played. They are also individually tweakable. Selected presets will light up each bank’s LEDs to show you which sliders and buttons can be used to modify the sounds.
Its a classic instrument, so no Midi or external control, but however its analogue sounds are rich and warm, and it is, after all, a classic analog string synth.
The Brass section creates Trumpet and Trombone sounds with independent attack and sustain controls.
The String section creates Cello and Violin sounds with independent attack and sustain controls.
The Organ section is 2-voice and has a Celeste sound available as well.
The Piano section offers two types, traditional or Honky Tonk. The ARP Quartet, which is completely identical to the SielOrchestra has been used by 808 State and Massive Attack for some of its great string sounds. “ Click here to search for synths on eBay
