Summary0007611: Timestreching automation? Stretching with changed tempo?
DescriptionI have a project where I frequently change tempo to help a bass player learn her part.

When I change the tempo of my session, all the MIDI tracks align nicely and I don't have to do any extra work to get them sounding as expected.

However automation lanes for the tracks do not change their speed according to the new tempo. I tried finding an appropriate option, but I couldn't. Maybe I missed something?

I tried fixing it with the time-stretch tool, but it doesn't operate or automation data at all.

I wonder what could be done about this. Maybe encapsulating automation data in regions, just like MIDI and audio regions- would allow timestretching them?
I guess that could also help link automation data to MIDI regions, and have them follow their parents.

I can imagine this could require major changes in how Ardour works with automation in the first place.

On the other hand - since MIDI tracks handle retiming to changing tempo very well, I guess it might not be so far fetched to expand such functionality to automation lanes too.
