fluidsynth-dssi gain problem

[Hermann Meyer <brummer-@web.de>]

Hello maintainer,

I've got a problem with fluidsynth-dssi use in Rosegarden as Synth-plugin. 
every time I adjust the gain under 0 (the default is -14) I've get a error 
message from rosegarden, that the gain is out of range.
So I have a look in the source and change the gain range in 
FluidSynth_DSSI_gtk.c line 835 

 - gain_adj = gtk_adjustment_new (-14, -96, 30, 1, 10, 10);

+ gain_adj = gtk_adjustment_new (0, 0, 30, 1, 10, 10);

that will work vor me

regards   hermann
