another example:
in a 6/8 measure you usually count the dottet quater notes.
So if I want a 6/8 in the tempo of 76 dotted quarter notes per minute, I have to set Cubase to
76 x 3 / 2 = 114
which equals quarter notes.
To get the clicktrack play the dottet quarter notes, you have to set the click notelength to 3/8 in the metronome settings menu.
This is the workaround, but it certainly isn´t thought out very well, let alone thoretically correct.
