I have just installed and activated a demo of Cubase 8.5 Pro (can't find one for the current version).
The installer is almost 10GB, some of this appears to be "content" but I did not see an option to select a folder for this. Is this a limitation of the demo? I am a bit pushed for space on my C: drive.
Other than that first impressions are good, not as obvious as Studio One for sure but MIDI options look impressive.
