what can .sty files be used for on psr sx600?

[Pickheaven01]

Greeting my friends.  I own a psr sx600 and a real novice.  Please help me understand what the purpose and usages are for .sty files.  When I downloaded an free expansion pack and opened it I discovered a .sty file included.  How am I to use this .sty file?  What is its purpose.  I have many midi files in a home collection.  Can they be turned into .sty files?  And if so, then what is there application and purpose?  Thank you in advance for assisting me.  I am a serious music lover also.

Hi PickHeaven

STY files are styles so you can use it to play backing on your keyboard .. If it's in an expansion pack it's probably meant to compliment the voices in the pack ..you can save it onto your hard drive or leave it on an USB and load it from there on your SX or even put it into your user files

Yes Yamaha have a free app that converts midi files to sty files ... look at the Yamaha site

Styles are the auto accompaniment mode that is the main purpose of all arranger keyboards. You drive them by playing appropriate chords. They are more flexible than midis as you are driving them in real time. These arranger keyboards are primarily designed for playing music in real time using styles to make you sound like a complete band.
You have many built in to the keyboard that are referred to as pre-set styles (pre-set by Yamaha). But you can also source and add additional styles, and also edit existing styles, sometimes custom built for specific songs, or even create your own - although this typically takes quite a bit of both musical and keyboard experience.
It is also possible to make a style from a midi using either Yamaha or other software, but they don't always turn out well, and typically need a lot of editing to make them acceptable.
If you are completely new to arrangers, start with pre-sets, learn to play the keyboard using them, then as you gain familiarity add others as appropriate, maybe move to minor style editing and graduate to major editing and midi to style creation. It's a long path.
