Starting with tomorrow’s nightly build, Ardour 7.2-123 supports VST3 plugins with multiple I/O busses. This allows for instrument plugins to have dedicated additional outputs.
Notably drum software which have direct outs (e.g. ezdummer, AD2), and also VST3 synths (e.g. surge) can now be used to their full potential.
Since the plugin meta-data is cached, this change requires VST3 plugins to be re-scanned, which can be initiated in Ardour Menu > Window > Plugin Manager.
This is a significant change, and while it holds up well in preliminary testing, there might be plugins that have issues. Please test, and if you encounter issues with a specific VST3 plugin it would be great if you could file a bug report at tracker.ardour.org. So that by the time we release Ardour 7.3 most kinks are worked out.
Thanks for the addition of this feature! It detects the number of channels properly now (tested with Kontakt 6 VST3). However, I’ve noticed a couple of significant bugs with parameter changes since the addition. The bug report is posted here.
This is great! This missing feature has been the main reason stopping me from giving Ardour a decent try. I’ve subscribed and tested the nightly, and initial tests are working well with VCV Rack on linux.
The ability to easily send out mono channels with minimum hassle is great also. Often the multi-bus implementation is hard-wired to only make stereo pairs available.
