It was a few years ago so it could well have changed. That said, I tried it again recently when they released the clip launcher and it crashed within a couple of minutes when adding vital to a track. I think that was reported and has probably been fixed but the remaining lack of recovery doesn't give me confidence.
I also reported the crashes and spent lots of time on IRC trying to find a solution when I was trying to use it but the ultimate response was that it was 3rd party vsts (and I believe my bug reports were never addressed) so I suspect nothing much has changed with it in that area. I never experienced the same thing in renoise, reaper or bitwig so I know which one I won't be using.
I mainly use Bitwig and hardware now so it's not really relevant to me but I haven't had great experiences with ardour and I consider losing work with no recovery at all to be pretty bad.
What are the replies like? Some have a lot so it doesn't appear they're struggling at all.
