The Siel Cruise is a really interesting instrument. It helped Siel branch out of the Organ building business and into synthesizers. Besides the Sequential Circuits Fugue version, the Cruise’s two sections were also available as separate synthesizers from Siel—the Orchestra and the Mono. The Cruise’s Poly section, the Orchestra, was also released in the USA by ARP as the Quartet. So there is plenty of this synth to go around under various names and forms out there. It is quite capable of some really nice Mellotron-like strings, a fair good piano, though the single-oscillator driven Mono synth is a bit slim due to being a single oscillator, but still quite capable of decent bass and lead sounds.
