I much prefer styles as opposed to SMF because I get to choose the chords (
and re-harmonize if I so wish; very difficult on a SMF unless you strip it down to only bass and drums) and also I can change styles in the middle (or any point) of a tune
at will and completely change the character of the tune.
Plus, it's extremely easy to extend the length of a song literally on the fly...putting markers in SMF works okay, but most people don't bother to learn how.
Like Gary, it has been my experience that
nearly everyone who use SMF are using commercial files and it's
extremely rare to find anyone who makes all their own SMF
from scratch. In fact, very few do any editing of the files at all, as the majority available (especially the commercial ones) are already very good to excellent.
I don't really care one way or the other how other players use their arranger...I just know that using styles has always worked a treat for me.
As far as the visual aspect from the audience...I don't kid myself that they think I'm playing all the parts, but they can see me doing lots of left hand chording and plenty of right hand work including using pitch and mod wheels. I don't sing so there is no voice covering the melody, so I have to work especially hard with proper sound/style choices to keep things interesting.
I've always worked steady and often at great paying gigs so I must have been doing something right. Even after retirement, I still get the occasional call, but unless it's extremely lucrative, or something for a close friend, I usually turn it down.
Plus, I'd rather voluntarily put myself out to pasture, than die snortin', kickin', and twitchin' with my nose in the mud on the track. I'm not ready to exchange my Arranger for a Harp.
I still play everyday, either for my own fun, or with some friends/neighbors as audience.
I still feel the Arranger is the veritable
Swiss Army Knife of keyboards....a little bit Preset (with some decent editing functions) synthesizer, a little bit Workstation...they've come a seriously long way from the boom-ticky-tacky 16 rhythms and 32 sound portables of not all that long ago.
I'm still on the honeymoon with my Tyros4 even after over two years of owning it, and it might possibly be my last major arranger purchase, as it covers my needs so perfectly.
