I am selling an original Siel Orchestra, a very nice sounding analog synth (used by Porthishead and Massive Attack). 

Here are the facts:

The Orchestra is a 4-part orchestral synthesizer from the classic Italian synth company, Siel (later bought by ARP and relabeled 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 LEDs to show you which sliders and buttons can be used to modify the sounds. 


Polyphony - 49 notes

Oscillators - Brass, Strings, Organ and Piano

LFO - Fixed waveform, speed, depth, delay sliders

VCA - Yes, individual attack and decay sliders for strings, brass and piano sections.

Keyboard - 49 keys


The Siel Orchestra is an original analogue subtractive synthesizer, a very characteristic instrument for its time with lush thick strings. Because of its Italian origin and its distinctive routing, the sound is not matched by any other similar synthesizers.

The Orchestra was produced from 1979-1983 and  later bought by ARP Instruments to be slightly modified, relabeled and then sold as the ARP Quartet. 


Synth can be checked and tested in Berlin or Hamburg. Shipping incl. vintage wooden case to European countries is possible. please just ask and I will check shipping prices on a per country level.
