Re: [LAU] Ardour crashing with error about not being fast enough.

Okay, so after continuing my search for a solution I can across someone with
a similar problem that ended up being cause by a bug in a effects
plugin(freeverb). I had about 10 plugins in my project and I narrowed it
down to the one causing the problem! TAP Equalizer. I don't know what the
actually problem is, but it causes ardour/jack to fall apart. Upon checking
out the website for TAP it looks like development has been dead since 2004
so I don't know if it will be fixed.

Ardour Rocks. Case closed.
