[LAU] swami soundfont in musescore

Hi, I've created a simple as dirt soundfont in swami, and I'd like to use it in musescore, but I'm not getting any sound. First thing, the soundfont plays allright in qsynth. In musescore I create a new score with a random instrument (say Violin), then load the soundfont in Display -> Synthesizer. Then I enter some notes in the Violin part, but I get no sound. The notes entered are in the correct midi range for the soundfont - to check I enabled Jack midi output in musescore and looked at what midi it was sending while playing the violin part. How does musescore associate an instrument in the score to one in the soundfont? I tried opening the "Staff Properties..." and changing the long instrument name from "Violin" to "baba" - that's exactly how I called both the instrument and the "melodic preset" in swami, but still I get no sound. It would be perfect if someone could provide a simple .sf2 and .mscz that "work" together, so I could hack on that. best wishes, renato
