Hi all,

For fluidsynth-devel list people, here is the complete thread of this message:
http://thread.gmane.org/gmane.linux.audio.users/50260

First of all: thank you very much, Roberto, for sharing your soundfont! Great
stuff!

QSynth is only a GUI front-end for the FluidSynth library. Any soundfont that
can be used with QSynth is also valid for the FluidSynth commandline client,
and any other FluidSynth front-end.

Some problems have been detected in FluidSynth regarding dynamic range when
triggered by MIDI velocity parameters, and have been fixed recently in the
FluidSynth development repository by S. Christian Collins, who is also a
soundfont designer and author of the excellent GeneralUser GS SF2.

I've been listening with your SF some pieces recorded with real Disklavier
instruments from this page: http://www.piano-e-competition.com/midi_2008.asp
some of them having a big range of dynamics, for instance, this one:
http://www.piano-e-competition.com/MIDIFiles/2008/Khmara02.MID

I think that the current development version of FluidSynth sounds much better
than 1.0.8 with these kind of music, but I would like to hear your opinions.

Regards,
Pedro
