Re: [Linuxsampler-devel] profiling, etc.

Garett,

Thanks for the update! So the problem with voice drops at ~6 voices is gone?

We've seen the streaming bug for quite some time now and this bug is
what's blocking us from release. I have some "holiday time" this week
so i'll try to debug this problem.
I've seen it on and off with pretty much every gig i have. Some more
often than others.
If i make any progress i'll keep you posted.

About the note off problem. I'm not sure if Christian is aware of it,
maybe he already is, but if he isn't then having a "test gig" made
sounds like a very good idea. This should be easier to fix than the
streaming bug.

Regards,
Vladimir.
