Strings muted sound

Hi, gang!!!

I wonder if there is some soundfont file which has the "Sordino" (muted) sound effect from arc string instruments (violin, viola, cello and double bass).

BTW: This muted sound is related with a lower nature harmonics level, which could be handle with the MuseScore soundfont player (or synthesizer). But... I really can not to figure out how.

Blessings & Greetings from Chile!!!
