Just returned from 5 days on the Caribbean.  On ship there were a few arranger musicians.  One group called 'From Russia With Love' was a family trio of wife, husband and daughter.  The woman played a G1000 and an E-36.  She used the E mostly for piano intros and endings, but I was surprised just how well this older lower end keyboard sounded.  She was very accomplished and seemed to be the musical leader.  The husband was a sax/flute player and filled in with a PSR1500.  He did some organ, strings and trumpet on it and it too sounded very good.  The daughter sang and had a voice I would characterize as very much like Karen Carpenter with a slight Russian accent.
Their arrangements were right on and very polished.  I asked how much of the arrangements were styles and how many were midi.  She said they made their own styles, but a lot of stuff had very specific fills and background, so I think it may have been midi from a style or vice versa.
There was also a solo pianist in the lounge who played a grand along with SMF off a laptop with VanBasco midi player.  He was much looser and I didn't care for his vocal style at all.
There was a modern band in another lounge, but the girl keyboardist played Roland RD700 & 300 and a Triton - heck of a player.
Lastly, there was a reggae band on the pool deck.  They would play all afternoon.  I guess that unless you're totally buzzed, constant reggae get too monotonous.  The keyboardist played an XP50 and an M3.
There was a violin-guitar duo, but I only heard them for a minute.
The stage orchestra was very good (big Triton) and so were the 4 singers, but the 8 dancers were so-so at best.
We had a great time avoiding tropical storm Noel for 5 days.  I got to meet Tony Rome in Cozumel and I heard a great piano player at Sloppy Joe's in Key West. Yeah, mon!
