Additional InformationBefore adding the Calf Vintage Delay I could work with the project for some hours without a crash. After adding the plugin it crashed within ~30 min.

Also some automations are used (LV2, LS Filter, Steve Harris) and Fader.

We are extremely unlikely to track down any crashes that happen in the presence of a CALF plugin and not without it.

Our official position is that you should not use the CALF plugins.

Paul - could you please elaborate, or point some sources to why do you discourage using Calf plugins?

2018-06-27 05:02

We get a steady stream of reports from people (mostly on IRC) whose sessions work great as long as they do not use a CALF plugin. They add the plugin and the session starts crashing. They remove the plugin or launch in safe mode, which disables all plugins, and the session works again.

There are no other families of plugins for which this happens. There are thousands of plugins. There are dozens which cause problems for Ardour users, on some platform. We do not have the resources to dig into each case, and the situation with CALF is so predictable that we prefer to just advise people to not use them at all. That doesn't mean they will always fail (and when they work, they are actually not bad at all). But it means that if they cause problems with a session, we are not going to investigate.

Thanks. I've created an issue on Calf Github and quoted your words there:

Thanks unfa & Paul for commenting again on this.I have problems with Calf while unfa doesn't and I'm really curious to know the reasons for this.
