Hi all, I was wondering if the following is possible;

If I have two keyboards, one, a Yamaha Motif XF, and the other, a Yamaha PSR-S970, can I replace some or all of the sounds in the PSR-S970's style with the Motif's?

In other words, if I play a Bossa Nova style (for example) on the PSR and I want to replace the PSR's drums for the Motif's drums, is it possible? Or, perhaps I want to replace the PSR's string sound with a string sound in the Motif, can I do that?

Is it easy?

Thanks for your time.
