In Cubase I have to either sum the compound signature and just use 15/8, or painstakingly write EVERY signature change (because oddly enough, these events cannot be duplicated or repeated).
I wont hold my breath on this, but a reply would be nice.
As regards displaying composite time signatures, Cubase can indeed do this (although a maximum of four, as opposed to Finale’s five )…
To achieve that, yes, you enter the “real” time signature as 15/8, then double-clcik on the displayed time signature.
However, as you rightly say, this unfortunately as no bearing on the click that you hear… best option there is to create a dedicated MIDI track, playing a click sound.
