I’ve recorded a track on MIDI keyboard with sustain pedal. The rhythm and tempo changes in my performance are imperfect so I want to adjust them by moving notes right or left, and usually I move all notes on the right of the cursor (Ctrl+R then Alt+A then Ctrl+Right/Left). But the pedal events on the pedal subtrack (predictably) remain unchanged and finally become trash. The only way I see is to remember the exact amount of the right/left movements I make on the notes and repeat them on the pedal events after every change. But what if I had a piece with 20 tracks and wanted to add a fermata or create an accelerando in the middle? Are there more fast and convenient ways to move stuff on all tracks simultaneously?
Is your arrangement created with musical or linear time resolution?
I would apply fermata and accelerando using tempo changes, which requires musical time resolution. If I needed to record a performance that has a lot of tempo changes, I would record without the metronome. Afterwards I would start from the beginning of the arrangement and use the ‘Adjust tempo to align grid at cursor’ right-click menu on the tempo lane to incrementally align the bar/beat lines to the freeform recording. Once you have the grid in place, it will be easier to add e.g. fermata by adjusting the tempo around the fermata note.
