Chris I did the tests (results below) on Fedora 8 using the Planet-CCRMA realtime kernel 2.6.22.10-1.rt9.1.fc8. The master volume was maintained at 50% throughout the experiments. Firstly, it is not possible to render the 'softsynth velo curve test .mid' file using `fluidsynth -a jack 'softsynth...sf2' 'softsynth...mid' ` within the terminal. If I only substitute the MIDI file with one of my own then I can render square waves. If however, I keep your MIDI file and substitute the soundfont with one of my own,there is no sound. So, there probably is a problem with the MIDI file. Then, I tried rendering your MIDI file from within rosegarden using the fluidsynth-DSSI plugin. Now, I can hear sounds. There is definitely a much broader dynamic range in tone series 3 compared to the other two and tone series 2 has the most restricted dynamic range. In tone set 3, the tones start at a much lower volume than those in set 1. So, the velocity to attenuation curve is evidently restricting the dynamic range. What is a bit puzzling though is that in the second tone set, the first and second tones are loudest and there seems to be a little audible difference in the subsequent tones. As a control, when I substituted your soundfont with a GM one, preset changes could clearly be heard for tone series 2. Regards.
