Hi all,
I am new to fluidsynth and i tried it to run it on my raspberry pi
computer.
its a small ARM board with a 700 mhz processor and 256 mb ram.
When i tried it it played the file for a few seconds and then it strated
to kind of grind or hum. sounded like a saw wave tone got quite low but
went up and down the scale.
here's the output of the console:
$ fluidsynth -a alsa /usr/share/sounds/sf2/FluidR3_GM.sf2 10.mid

Have you tried a larger period/buffer size, e g -z 4096 or so? Does that
make any difference?

Also; as someone else said, you have not set your system up for
low-latency audio, i e the /etc/security/limits stuff. The risk of
underruns are big, especially when you run it together with the lowest
possible latency (256 samples).
