Questions about the new functions implemented on OS v2

Q  On OSv2 I loaded some User Styles using the “UserStyleLoad” menu but it sounds different than the original.
For technical reasons, there are some styles that cannot be properly transformed to be used on the EK-50. KORG will not be liable nor give any warranty that User Styles will be able to be played with perfect accuracy so please be careful.
Q  On OSv2 I loaded and I am currently using some User Styles. In some of these user styles, when selecting a SET LIST in which VARIATIONS 1 to 4 have been registered, it will insert a measure and play some other style elements.
If you have access to a Pa50, Pa50SD or microARRANGER, there is a way to avoid this issue. Just select your preferred VARIATION (1 to 4) as the default Style Elements and then load that modified data on the EK-50.
