I don’t think people realise the extent to which control will be given up in the new subscription-based world, where you own nothing; sure, you may “possess” a computer, but someone else, somewhere else, will have the power to render it useless unless you pay up. It’s the Al Capone business model.
Oddly enough, thanks to the wonderful work done on the MIDI Remote script for the Presonus FaderPort 2 by @WEM and @CKB I recently purchased one to replace my AlphaTrack, and it comes with a free license for Studio One Artist, which I will be exploring. One of the considerations when choosing the FaderPort 2 is that it is a class-compliant USB device and will therefore also work on Linux, and, should a Linux version of Cubase ever materialise, the MIDI Remote script will also work there.
