Nice, squeak.

Try this, as well (if Yamaha's can do this)... set up the large string layer to be less velocity sensitive, and the violin layer to be more so. This will make the violin section of the strings to 'pop' a bit more as you play harder, giving you more timbral variety as well as volume.

Strangely, the inverse set up can also give you playable results. Play soft, you mostly hear the small ensemble, play harder and the rest of the ensemble starts to dominate.

This is the secret of good string parts... Not only should there be a volume difference as the dynamics change, but the timbre of the patch should change too. That's what REAL string sections do.

Merry Christmas.
