In all previous Cubase versions, you could type the number of repetitions using a keyboard shortcut (CTRL+K by default) followed by a numeric keyboard input. With version 13, you now have to painstakingly select the number with the mouse in order to select a different value. Similarly, the “shared” button can no longer be selected using Tab & Space, which is really inconvenient, as it is much easier to perform such operations using the keyboard. Please bring this function back!
I can confirm this.
