[fluid-dev] Help with setting volume control

[scott andrew franco]

Hi,

 

I am using Fluidsynth library in my program (Petit_ami on sourceforge). It is working well, but

my result is very low volume output.

 

A search found many other references to low volume, and the standard answer I found was to turn up

the gain on the command line version of fluidsynth (I believe -g or "gain" option). Of course that does not

apply to users of fluidsynth as a library.

 

I have had good luck finding various parameters via the settings call. The

"synth.gain" parameter should do it:

 

"The gain is applied to the final or master output of the synthesizer. It is set to a low value by default to avoid the saturation of the output when many notes are played."

 

It is 0-10, but is defaulted to 0.2.

 

However, changing this parameter had no effect on the output volume, I tried all the way up to 10.

 

Other details: I am using alsa device. The device it is using (by examining "audio.alsa.device") shows as "default".

 

Any help appreciated.
