KORG TRINITY PRO (REFILL)
Korg Trinity is a commercially successful synthesizer music workstation released by Korg in 1996. It was also the first workstation to offer modular expansion for not only sounds, but also studio-grade feature such as SCSI, ADAT, various sound engine processors, audio recording capability, and more. It was considered one of the most comprehensive music workstation, in term of features, at the time.
Ex-Dream Theater keyboardist Derek Sherinian in collaboration with KORG sound designer Jack Hotop created Sherinian's signature guitaristic lead sound on the Trinity in 1996.
Many users to this day feel that it's successor, Triton, never had the same "sound" and the Trinity had a more airy/clear sound to it.
