Siel Orchestra Project Machine

” Rare Siel Sielorchestra synth. Sold as spares or repair as there is no audio output. When the switches are moved the lights come on.

Later it became the Arp Quartet when Siel were acquired.

Obviously no returns.

Previously sold to a buyer who didn’t notice that it needed repair.” Click here to visit listing on eBay

Siel Orchestra

” Good condition for age (see photos). A few scratches and chips to woodwork, but nothing major. All keys and controls work, except for the spring on the Brass Mute key (but Muting still works if switch held)

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. ”

This unit works and sounds great it doea have a couple of issues.

The mute switch toggle has come off switch does work you just need to push something in the slot to flick it. The volume pot is very crackly if you set it in a good position and leave it it sounds fine and is very useable. Top of the reed button is missing but button still works.” Click here to visit listing on eBay
