Senjin,

I have created a new version of FluidSynth with a proper fix for the lack of velocity response in FluidSynth.  Now FluidSynth's velocity response should be equal to the SoundFont engine on the Sound Blaster Live! or Audigy sound cards.

Here's a link to the source code:

I'm not English native speaker so sorry for the mistakes...

I use fluidsynth 1.0.8 with qsynth 0.3.2. I noticed the following problem: When I play my electric piano connected via MIDI to the PC the dynamic range of the sounds played by fluidsynth is very low - much lower than of the sounds from the audio output of my piano. All the notes from fluidsynth have very similar loudness.

I noticed the problem using two popular soundfonts: naturalstudio ns_kit7free drumkit and FluidR3GM.SF2, so I doubt that this is a problem with my soundfonts.

I'm not soundfont expert, but some time ago I read that there are two ways of assigning sample dynamic to MIDI velocity values: linear and logarithmic. Some soundfonts require one, some another. Using the wrong one leads to wrong dynamic. I guess that this is the source of the problem.

However I couldn't find in qsynth nor in fluidsynth an option to chose the dynamic mode. Is it implemented?
