I have a midi file which was recorded live but without regard for the tempo of the MIDI track, so for example a note that should be on the fourth beat of the first measure (4/4 time) is actually landing on beat 2.5, i.e. the music is too fast to line up with the beats as defined by the project. Can I select the entire track and apply a scaling factor that changes all note start times by 4/2.5 (or however the math would need to work out) so that the notes are then aligned with the measures? Once it’s close enough I can quantize to exactly line it up. I used to do this when I used Cakewalk and I’m sure it must be possible in Cubase but I haven’t been able to figure it out.
The Object Selection tool has three modes, one is the resize mode. Using it you can resize a part using the mouse, and the midi events within resize proportionally.
The Logical Editor would permit you to apply a scaling factor to position and length. (there is a preset called “Double Tempo” in the L.E. Standard Set that is ready for you to enter your values)
