I don't think so, I'm going to use the SVN sources anyway. My executable is 
statically linked, because FS is not available as a standalone package in the 
N950 SDK at this moment. Later, if things go well, we can try to push the 
package to the Meego repositories and release a dynamically linked bundle.

More findings about the after-release noises. They appear with floats and 
polyphony limited below the default value. When using doubles, limiting the 
polyphony to 32 causes messages like "error: Trying to exceed polyphony in 
fluid_rvoice_mixer_add_voice" and "warning: Failed to allocate a synthesis 
process", the sound is silenced but don't produce noise. With floats and the 
same polyphony limit the messages don't appear, but noise is generated and 
can't be stopped.
