Resize a MIDI region

Hi all,

in MIDI-> transform, what is the correct setting to reduce a MIDI region by 25%?
(So if the initial length of the region was 1, it now becomes 0.75. Any internal ratio must remain unchanged).

Thank you,
a.

Select the timefx tool, then stretch the region.

Thank you.
Now I resize the region “by hand” using the mouse, .
But there a way to enter the exact value of the reduction?

Current versions of Ardour have a way to enter an explicit percentage in the stretch dialog.

I am referring to the Ardour 8.1.0 version…

Too old for that, sorry.
