Midi regions slow rendering down

(Kazoo) #1

Hi there!
I have midi regions with lots of events in them and when such a region appears on the screen, scrolling becomes very slow because the drawing takes so long I guess. Is there something I can do about this? Not drawing the content of the region at all would be an option as I edit them somewhere else anyway. But I didn’t find how to do that. Buffering the drawing (similar to the peaks thing for wav regions) would also be cool but I think that’s not implemented, is it?

All the best!

Probably not even related to MIDI, Ardour doesn’t perform well with many regions in general:

Hmmm…
I don’t have any of those problems. Probably because I don’t have many regions in general. But once a midi region appears on screen (like when I have several tracks and scroll down until I reach one with midi in it), it starts to become very laggy, so I’m pretty sure that my problem is the midi rendering.
