Is there a conflict between a sondfont sets?

[Borys54]

Hi everybody!
I'v got three sets of soundfonts.
First built-in Va synth, second additional Yamaha set and third Korg set.
Each one contains for example GM 0 - 0 set.
Is there a conflict between them?
Which one is available for a midi player?
Maybe all of them?

Thank You.

vArranger uses only 1 presset for 1 voice.
The last loaded replaces the previous one.
It depends on sf2 file name.
Loading of Soundfont files is sorted alphabetically.
