Hi all,

I am new to fluidsynth and i tried it to run it on my raspberry pi
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

Any help appreciated.
