Thanks for a fast reply!

One of the soundfonts I tried was the flute soundfont from the
soundfonts.it. The direct URL to the soundfont is:


It’s also available on this page:
(it's the 2nd sound from the top)

The sound is fine until the vibrato comes and the sound starts looping.

I am using heavily modified Mdk 10.0 Community on an Amd64 3000+ (Mobile)
notebook running 32-bit Linux 2.6.7 kernel with many low-lat patches and

I tried both the latest tarball version of fluidsynth and the somewhat older
rpm version from Thac's rpm's. The result was the same in both cases.

Hope this helps!

Best wishes,
