ARP Solena String Ensemble, a fully-polyphonic multi-orchestral synthesizer that features a 49-key keyboard and is manufactured by Eminent BV (famous for their Solina brand).
It can be used to make the sounds of viola and cello as well as trumpet, cello, contrabass, horn, cello and trumpet.
To make the keyboard polyphonic, it uses an ‘organ-style’ divide-down technique. The instrument’s distinctive sound is due to its built-in chorus effect.
ARP Solena String Ensemble was used by Air, The Eagles, Elton John, Pink Floyd, The Cure, Joy Division, OMD, Josh Wink, STYX, Tangerine Dream, Keane, Japan, and New Order.
