Hello Louis, I think rather than a script, FluidSynth could try and be smart about what audio driver to use by auto detecting what is available and selecting accordingly. Determining what sort of values should be used in regards to latency though, could be tricky. But depending on the a

Hello Louis, Glad things are working for you. As for having a page somewhere with information on getting low latency from FluidSynth, sounds like a good idea to me. I added a wiki page with some initial information, which is accessible from the FluidSynth documentation page. Feel free to

How difficult would it be to have FluidSynth generate (or come packaged with) a test sf2 file which would be played by FluidSynth and listened to programmatically for any problems? The script could run during package configuration or with a command line parameter like --calibrate. A pseudo-code

The below email was sent just to me but I would like to share it with the list. That is a really good idea, but a better idea might be to have a "startfluid" script that is provided either by the distribution or is part of the fluid synth team that works like the startx script. ie it starts up fli

Quoting "S. Christian Collins" : I noticed that the Sostenuto pedal (CC 66) doesn't seem to be implemented in FluidSynth, unless I'm missing something. I think this feature should definitely be implemented at some point. Do you all agree? -~Chris Hello Chris, Indeed the SoundFont specifica
