Description: Fluidsynth is unusable when trying to use multichannel front ends

The sound is terribly distorted when used with applications like fluidsynth-dssi.

Here you can find the discussion with the fluidsynth-dssi (and dssi) developer Sean Bolton:
http://aur.archlinux.org/packages.php?ID=19764

The bug is also discussed on fluidsynth mailing list here:
http://lists.nongnu.org/archive/html/fluid-dev/2010-09/msg00050.html

and follows to an opened ticket:
http://sourceforge.net/apps/trac/fluidsynth/ticket/87

Seems like this happens when fluidsynth is compiled to use doubles, on some machines.
It solves adding "-Denable-floats=yes" as cmake flag. (Tested on my Arch 64)

Additional info:
* package version -> 1.1.2

Steps to reproduce:

Run jack (by shell, qjackctl or patchage)
Load a soundfont through fluidsynth-dssi (ex. fluidr3 in aur)
Select an instrument
Connect a midi source to fluidsynth-dssi and its output to a sound card out
Play some midi events ( or just press on Send Test Note)
Listen to the big mess
This task depends upon
