Hi, I have an imported file and the chord symbols get in on weird rhythmic positions (like an unquantized MIDI file: E.g. a 128th before the barline). Edit | Requantize… does not do anything on chord symbols, though. I tried to drag them by mouse which snaps them to the grid, but I only get one at a time…
Is there any way to put a selection of them to e.g. quarter note positions only? Your help will be appreciated since I this problem repeatedly… 
Hi @Waldbaer,
I don’t think that there is a quantisation functionality for Chord Symbols.
But if you use the keyboard instead of the mouse it would be faster:
Alt(Option)+left or right arrow key to adjust the position of one selected chord symbol, then right arrow key to move the selection to the next CS…
@Waldbaer a further tip: set the grid resolution to quarter note, so you need less clicks to move the chord symbols 
Thanks for your reply and thoughts! So it snaps if a single chord symbol is edited, but keeps the (exact!) relative positions if more than one is selected. This is indeed interesting - maybe I can write a (Keyboard Maestro?) macro to go through them. I still need a possibility to understand if it’s before or after the main position to make this work, though…
It seems, the problem comes by offset values in the MusicXML I import from my music recognition software (no idea why these are used there). If I take the file to be imported before and search&kill these “…” lines with a text editor, I don’t have the problem in Dorico.
I don’t see a good way to fix this afterwards, though - if anybody has an idea, please share!
