I played on RS-5 at the store once, if we`ll compare Triton`s arpegiator to RS-5, I like Triton`s better, RS`s triggers only one tone guitar, organ etc... those kind of arpegios I can play my self (if I try hard), but Triton`s arpegiator plays multiple tones, like guitar strum, pad, strings, drums,all at once.
About XV-88, I`ll admit, that I never played on it, just saw it in a magazine,and I heard that that XV tones are the "best",(I wished that Roland would make a XV-88 with 61 keys).I`m also interested now about Fantom-s, isit like Fantom?. Now I`m "strugling" between these synths:
KORG TRITON,
KORG KARMA,
ROLAND XV-88,
ROLAND FANTOM,
ROLAND FANTOM-S,
ROLAND XP-80,
YAMAHA MOTIF.
