massichat, I'm glad you found it. I'm not always at my BIAB computer and have to try to remember these commands.
Thank you, this function would be even more impressive if it was available individually for any track, but without touching the chords this time: just change the speed of the phrase of a track by for exemple : doubling (2X speed) or slowing it down (1/2 speed).
I saw it in "track settings", I tried it but it had no effect, it concerns maybe just Real tracks.
