Hi David,

some days ago I reported about strange crackling effects using single 
waveforms. With the new jOrgan release (containing FS 1.1.2 final) the effect 
appears on other machines, too. Please have a look at the thread in the jOrgan 
user list:

Many thanks and Regards
Bernd.

Thanks for the testing, Bernd. I would need a little more information to
be able to solve these bugs.

 * Do you also have the sf2 used to render these files?

 * The initial crackling sounds like underruns, what are your audio
output options in this rendering example?

 * The difference in what you call "richness" between the two examples,
sounds like either difference in handling cutoff, or chorus, or a
combination. I'm not sure though, and I believe S Christian Collins is
our expert on this matter. Christian, perhaps you have some thoughts
about this issue?
