[fluid-dev] fluidsynth with realtime kernel

[Rui Fan]

Hi everyone,

I'm using fluidsynth 1.1.2 under Ubuntu 10.04, with latest realtime
kernel, connect to RoseGarden 10.04, playback some midi files.
Sometimes I encounter this error message, and all sounds off.

Does this mean fluidsynth is not compatible with realtime kernel ?
On my laptop there is a rather big latency when using default kernel,
so I'm trying realtime kernel. On my other desktop computers, the
latency for default kernel is accepted.

Any info is appreciated.
