I tried to use the sounds from my 5080 with my G1000.... it had major issues with timing... I think one or both the processors were not up to the job..
I did use the JV1010 with the G1000. It worked but it sounded better with the G1000 sounds..

Use Style composer...you can copy any style part of any style to any style or variation..
Save the change as a user style..
You can retain the style parts and mute them with an assignable...
