I use and edit a lot of drum maps. In Sonar I was able to “quick group” parameters for multiple notes and change them all at once. ex: Select all cymbal notes and change their midi channels at once. Is one-at-a-time the only way to do this in Cubase? It sure would make my life easier if I could change multiple note parameters at once.
Not sure if this helps but I setup a KC for select all notes of Same Pitch Same Octave, select one of the drum notes you want to change, then use the KC, then change whatever you want, pitch position or velocity, you could also have an Event List window open and make changes there
Key Command set under Cubase’s File menu/Key Commands. May take a while for you to set up close to what you need. Cubase is more customisable than most DAWs but that also means lots of preparation by the user to get things where they are needed for some jobs.
the best way I found, is to save a drum map file on your file system.
open the drum map file using your favorite text editor (outside Cubase).
open ‘search and replace’ from editor menu bar and replace the parameter line as you wish.
for example, if you wish to replace all notes channel routing to 1 instead of 10, replace the value on the channel parameter
from 9 to 0 (note that this is zero based value).
