Hi - I'm looking at remote playback of Cubase projects to hear how they sound on different speakers.
Is there any need for the Cubase project to be played BY Cubase? Export a wav file, carry it around on anything convenient. An iPad seems unnecessarily big and heavy, but if you have one lying around...
You don't have to write songs. The world doesn't want you to write songs. It would probably prefer it if you didn't. So write songs if you want to. Otherwise, dont. Go fishing instead.
