Simone Sedda

Manufacturer: SIEL
Model: Orchestra
Country: Italy
Year: 1979-1982
Keys: 49

The SIEL Orchestra is a 4-part orchestral quite rare synthesizer from the classic Italian synth company, SIEL (later bought by ARP and relabeled the Quartet). 

It produces its sounds from a divide-down oscillator network and therefore has 49-note (unlimited) polyphony.

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.

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 Hony Tonk.

Becsuse of its Italian origin and its distinctive routing, the Orchestra sound is not matched by any other similar synthesizers.


The ARP Quartet, which is completely identical to the Orchestra has been used by 808 State and Massive Attack for some of its great string sounds.

Although it’s not been recently serviced the synthesizer is in very good working condition and its aesthetic conditions are as shown in photos.

The sliders do not produce any noise and all the switches and buttons work fine.

Its dimensions and age would recommend to pick it up in person, anyway shipping is also available, but I won’t be able to accept any return.
