[Ardour-Users] Calf Multi-Band Comp not playing nicely with Ardour 3.x?

[Benjamin Scherrer]

Hey Aaron,

I always had issues with the Calf plugins when they were in development,
i.e. with some alpha or beta builts from svn (or whatever they use).
This was a while ago. So I would make sure that you have the newest
release of the Calf plugins, not some older versions. They were quite a
while in development, so people used them when they weren't completely
ready to be used.
Apart from that, I guess it's nearly always the plugin's fault if
something goes wrong, most plugins work quite well with any Ardour version.

Best
Benjamin
