Esline is a vintage Arp Solina String Ensemble emulation.
ARP Solina is a multi-orchestral machine with violin, viola, trumpet, horn, cello and contrabass. The contrabass and cello selectors can be used to turn on a 16' or 8' monophonic bass, which is triggered by the lowest of the keys one presses. The bass runs from C0 to G1 and stops there.
Cello, bass, viola, violin, trumpet, horn.
