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: http://jorgan.999862.n4.nabble.com/jOrgan-3-11-first-beta-td2535918.html#a2535918

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? // David _____________________ next part ______________________ Eingehende eMail ist virenfrei.
