[ardour-users] cmt or at least freeverb for osx?

[Eric]

Two things to report:

1.  My artist friend has abandoned ardour and returned to cubase
because of all the choppiness in the recordings despite trying
everything one typically would to reduce xruns (not sure whether the
actual problem was xruns, dropped samples, etc.).  Perhaps its a
compatibility issue with the presonous inspire firewire card she has,
not sure.  It works fine in cubase.  It seems to me that this is the
biggest barrier to normal users using ardour...if there are problems
like this, it's non-trivial for even advanced users to debug them.
I'm not sure if there's some way jack could do a better job
monitoring/diagnosing such things...even automatically suggesting
higher buffer sizes, or better, calibrating a good buffer size, would
be a start.

2.  She zipped up an ardour session directory and sent it to me.  I
tried to open it in linux and it segfaulted:

I ran ardour from within gdb, went to open the session, and got this:

I was then going to get a backtrace for every thread using gdb on the
core, but could only get the first one:

Not sure whey this happens:
