EK-50 Cannot select different Sounds without changing Style

[mrkram]

I would like to play the same style but select different sounds (using the registration banks) while that style is playing.

Right now I also need to select the same style and save it into each of the banks which have those sounds.

However for live performances the same sounds are required to be played with different styles.

eg Song1; Style 1 , Sound 1,2,3,4

Song2: Style 2, Sound 1,2,3,4

Presently I have to use 8 banks for achieving this instead of 4.

Is there any way to avoid this?

Thanks in advance
Manoj
