Richard: I concur that Yamaha's specificly dedicated Hawaiian styles are slim pickings. But in addition to the 2 Tyros Hawaiian preset styles and the two others I sent you, there are a number of other internal styles in both the Tyros & PSR2000 that I find ideally suited for Hawaiian tunes.
'Happa Haule'
http://www.squareone.org/Hapa/ Hawaiiian music is actually a take off of Country music so acoustic guitars with country swing is prevelant. The Tyros' mega acoustic guitar voices sound impressive, so I find there's a lot of Tyros specific styles to choose when playing Hawaiian song material. Here are just a few suggestions of other Tyros/PSR2000 styles that I find work well for Hawaiian songs:
Country Swing1: 120
Country Ballad: 72
New Country: 105
8 beat Ballad : 101
Easy Ballad: 94
8 Beat Adria: 100
Pop New Age: 66
Unplugged 1: 120
The IMPORTANT point I'd like to make is that when selecting a style for a particular song, don't limit yourself to just the Style category you'd expect to find it. Checkout other (unlikely?) style categories as well. Also experiment with changing the 'preset' tempos (sometimes to extreme). You'll be surprised how many MORE other preset styles options you suddenly have available inside the keyboard suitable for your songs. I also suggest creating voice registration banks, one for each genre of music, which will free you up for experimentation to explore other style possibilities. My custom Hawaiian Voice 'registratin bank' file consists of of the following:
1. Piano
2. Stage EP
3. Aloha Guitar (great built in pitch bend)
4. Steel Guitar
5. Harmonica
6. Accordion/Strings
7. Marimba
8. Flute
Also, sometimes just muting/changing one voice in the style accomp will make a style more appropriate for your song as well.
Richard, good luck on your luau gig. Just don't forget your lei and hawaiian shirt, Hang loose bro'. - Scott
