Korg Micro Arranger or PA50 SD Question and HELP Please?.

[Dnj]

Hi ..... although I have owned & performed with most of all the PA models I'm a little rusty on Korg arrangers OS after all this time on a Yamaha unit with this Micro arranger unit.... I have a few question if anyone can help me......

1- After you select a style to use, how can you then select, change and save NEW STS sounds and then SAVE it ALL to the Style & to a USER slot so I can bring it up when needed on stage playing ?

2- If there is a sound or sounds combination you like in a factory style STS can you copy it and use it in another style STS & then save it all to USER also?

I know I'LL HAVE MORE QUESTIONS....and let me thank you all for any help you can give me in a step by step way. I know it will all come back to me once I start doing it.
