COMPLEX ISSUE

hi,

i just had a problem that’s tricky.

i have a session where i have MIDI tracks and AUDIO tracks.
at one point i did some “DELETE TIME” and kept working for hours.
now i get into a MIDI region that i have not edited since that DELETE TIME.
i get in and for some reason i do an UNDO.
because i’m inside a MIDI region i guess there’s this “MIDI UNDO” that is in memory or somehting.
the result is that i get all the tracks beeing UNDOED on that “DELETE TIME” i did.
and it doesn’t want to REDO…
was a big mess because i had some tempo change and prefered to to a backup.

some ever had this ?
