yea, it’s a real good question. I have spend hours to find a way to copy or duplicate from a given stereo tom sample (which is only recorded at the right channel) into the empty left channel in GA 5 sample editor. Maybe it’s not possible - as here is nobody responding to that question. And I just like a bit more convinience, insted of recording the output of DA into a stereo audio lane and after that re-import it back into GA.
I will check. I don’t recall seeing a convert sample to mono button. But you should be able to render to mono in your given DAW. I dont use Cubase but FL.
