"First you think it has 4 basic sounds but it is the 80s so the piano is of course does not sound like a piano at all, and the others also very very diferent what you expect but the result is surprisingly great, you simply do not want to stop playing!
The equalizer is a real plus! It can change the sound of every patches and it is a really hands on modification tool."
Comes with the TAUNTEK mod installed on it (it enables CC midi controlling and many other features..i ll provide also the Maxforlive/Reaktor devices to control it in any Daw)
New Battery installed.
This Expander Ex600 combined with another SielOpera6 or DK600 let you expand voices from 6 to 12 simultaneously, keyboard splitting and layering and much more."
"Rare, Siel Expander Synthesizer, actually New In Box! Never opened since 1980s, it is still stapled shut from the factory. Be the 1st to open and work this great analog wonder."
From the listing "The last one sold on Reverb was 4 years ago." Not sure about that. You can see a few posted here. Remember, you can search for any synth + auction here on MATRIXSYNTH to bring up previous listings.
"Also sold as the ARP Quartet this keyboard offers 4 parts: Brass / Strings / Reed / Piano
Nice moogish filter on the brass part and the strings sounds are not too bad either. They do use the same TCA350 BBD chipsets as other classic string machines like the Eminent Solina, Logan String Melody or Crumar Performer."
"Quick video of a SIEL Orchestra I just serviced, in order to demonstrate the differents sounds you can get out of this instrument.

I use a sustain, pedal as some point, mainly on the piano part.
Recorded dry and no treatment."
"Great vintage analog synthesizer that is in decent shape for its age. Everything is fully functional. As it sits, some of the sliders are a little scratchy when slid but can be exercised and freed from dust very easily. There a few that are slightly bent but does not affect functionality. There is one minor scratch on the face plate, not too noticeable and can only be seen under the right lighting. Tried to capture, see photo.
These are getting more rare. They have a great built in chorus, flange and useful eq.
The Brass section alone is worth it. Calling all collectors this is the only one on sale (online) at the moment."
"A super rare DK-700, the Siel flagship synthesizer released in 1986, equipped with a DIY Arduino interface to control all the synth parameters in real-time using TouchOSC on Android/iPad. The machine has been recently serviced by a professional technician and actually looks and sounds great.
Released in 1986, the DK-700 is the best and last synthesizer produced by the Italian SIEL right before the joint-venture with Roland Corporation and its subsequent turning into Roland Europe. The DK-700 has been on the market for less than one year so only few hundreds units were sold and this inspiring synthesizer never received the love it actually deserved.
"A wonderful string synthesizer from the house of SIEL. It is well laid out and sounds as stringy as it gets. A nice addition to your synthesizer arsenal. Works really well and is in nice condition."
"Rare vintage Italian synth. Had it completely gone through and brought back to new working condition by Digitron Electronics. Has an EQ section, a flanger modulation, an LFO, an octave down and four sound parts sections that can be combined."
"Combining two very rare oddballs - both manufactured by CRB Elettronica in the late 1970s :
The CRB Computer Band 2000 and the CRB Voco Strings.
The Computer Band 2000 is an analog auto-accompaniment machine with a range of chord and arpeggiator sounds with decay controls, as well as a bass section and a drum machine with individually mutable sounds.
The Voco Strings is CRBs take on the Roland VP-330 - a string and vocoder machine.
Were there any other commercially produced vocoders in Europe apart from this one and the Sennheiser VSM-201? Let us know in the comment section.
We're letting the CRB Voco strings process the Computer Band, via the regular audio input, while a third player, the Siel Cruise, a lovely Mono / Poly machine, is connected as an external carrier signal, via the instrument input.
More videos of this lovely combination will be going up soon.
Vintage Audio Institute is a gear vendor and recording facility in Florence Italy."
