Larger number of drum maps considerably slows down opening and closing of projects

To face the issue, please:

  1. Create a batch of 500 or more dummy/test drum maps;
  2. Open a new project;
  3. Create an instrument track;
  4. Load the drum maps (Drum Map Setup > Functions > Load…)
  5. Save the project;
  6. Re-open the project;
  7. Re-close the project.

Result: closing and opening the project becomes very slow. What was a matter of seconds is now a matter of minutes.

Although technically this is not a bug, it does indicate a problematic implementation of drum maps in Cubase and thus calls for further streamlining and optimization.
