On the Korg microARRANGER, when pressing the 'WRITE' button to save a parameter setting,
I'm often given the option to save it to 'one' of the following areas:

Style
Performance (also known as a reg. by Yam players)
STS (single touch setting)

For example:

After changing the settings for: fill-1 / fill-2

Menu Button: Preferences > Page 20 > fill-1; fill-2 > off; up; down; dec; inc; 1-3; 1-4; etc.

and then pressing the 'WRITE' button,
I'm given the following save to location options:


Perf.Name:StereoGrand
Perf.N:01-1 StereoGrand
STS N:1
Current Style


which location is it best place to save it to?
In addition, what's the difference between:

Perf.Name:StereoGrand
Perf.N:01-1 StereoGrand

Aren't these two locations the same?


Also, when saving a Korg Performance
is it possible to save or call up only
a specific category of settings in a Performance as
Yamaha PSR/Tyros series keyboards support with
its 'reg.memory contents' checkbox category feature?

Thanks in advance for all help and assistance on this topic.
