Hi Jörn,
I'm not sure about the mentioned approach, since I'm not familiar with

the jconvolver source, only zita-convolver (and only from a user

p.o.v; haven't modified it). So I don't know that this multi-threaded

approach you mention is something jconvolver actually does, or is it

just the usual workings of zita-convolver (which I use in a really

simple manner).
I will look at the jconvolver source to educate myself about said

approach when I have a bit of free time.

As usual: it works for me 10 out of 10 times (at least for what I do

and how I work), but YMMV. I must admit that I don't use freewheeling

that much, but some test passes with various projects (some simple and

some big) on two machines, one older single processor and one fairly

recent quad core (both 64 bit), indicated no problems. Of course this

means nothing at all in this case.

That would be definitely nice but currently missing. I would say that

if there is a problem with jconvolver, IR most probably also has this

problem.
I tend to listen to what I commit, though, so I bounce in realtime.
