Less Reverb??? How?

I want my soundfont to play with less reverb in musescore.

I opened the soundfont file (marchperc3.sf2) in Viena, and when I click the keys to hear the sound of each instrument, they all sounded like they were being played in a cave (the reason for this was because the reverb amount was set at 50%). I clicked Reverb in the upper right, and dragged it down to 15%, and clicked okay. Then when I clicked the keys, everything sounded very nice. I clicked Save (this is all being done in the Viena program, haven't opened Musescore yet). Then I opened MuseScore and added the soundfont into the Synthesizer and click Save to Score. I wrote a few notes and played it back, and it sounded all cavey, like nothing was saved earlier. I was hoping to make all of the sounds in the soundfont to 15% reverb, then be able to open the SoundFont file in MuseScore and have it sound like it did in Viena, but the Reverb settings in Viena obviously didn't save.
