The Solina String Synthesizer is the rare brother of the String Ensemble. Only about 100 were made, so they are very hard to find. The String Synthesizer originally have a standard wood case like the Ensemble models but some white models exist too. The String Synthesizer is basically a combination of the String Ensemble and the Arp Explorer 1. You can select between Preset sounds (trumpets, flutes, and clarinets) or make your own using the added VCO, courtesy of the Explorer. It offered way more sound editing than the String Ensemble, and was capable of more diverse sounds.
It was built by the Dutch company Eminent in Bodegraven, Netherlands. Supposedly only about 100 were ever produced. The addition of the ARP Explorer to the Solina string sounds made for a very powerful combination.
This synth had four keyboard modes:
1. Strings Only
2. Strings through the Explorer low-pass filter
3. Explorer voice combined with the lower Solina keyboard (contrabass and cello)
4. Explorer voice combined with the upper Solina keyboard (viola, violin, trumpet, horn)
