Hello,

In Ardour 6.9.0 how can i flip a midi region around a vertical axis and about a horizzontal axis?
It’s possible to do it?

Thanks,

a.

Regarding horizontal, you can use Region > Edit > MIDI > Transform:
subtract the current note-number from 127 (or any given mirror-axis value):

Regarding the vertical axis, I think you’re out of luck. Region >Reverse only works for audio. It is also somewhat ill defined for MIDI. You can render it to audio and then reverse it.

Thanks, it works fine.

Regarding the vertical axis, for example in Rosegarden (Linux) it can be done: in the matrix editor, there are “Invert”, “Retrograde”, “Retrograde Invert” editing functions.
Retrograde function flip a midi region around the vertical axis.

Bye,
a.
