Got so absorbed hacking my UG802 that I completely missed this: https://community.ardour.org/node/7219

So not only can you add video to your Ardour project but now it’s also possible to chain multiple LV2 plugins that accept MIDI. The video support is the great work of Robin Gareus and it was actually a presentation on this functionality that got me acquainted with the Linux Audio meetings at the HKU almost 3 years ago. So yes, he’s been working on it quite a while so I assume it works well.

I have actually never worked with Ardour, I’ve always used Qtractor. But maybe it’s getting time to check out Ardour too, especially now that the MIDI part is stabilizing.
