A useful feature for my workflow would be the ability to drag tempo change markers without affecting the position of tempo changes that are later on the timeline. By “position” here I mean the relative position of regions and tempo markers. There are potentially many ways to implement this feature, but the simplest I can imagine is basically a “wall” - a marker that says “tempo changes on the left of this marker do not affect the position of stuff to the right of the marker”.
Does any such functionality exist in Ardour at present? I’ve searched around and tried different approaches but none have allowed me to reliably reorder sections of music that are of different tempos.
