As I don’t think there would be much appeal to SB due to the market size, platform complexity and code age of Cubase/Nuendo, the best thing to do is to start a private GoFundMe campaign to prove that there is a market that would pay (don’t forget they’d have to get up to speed on supporting Linux systems and the myriad options therein), so I think the goal would have to be quite large.
Heck, we can’t even get them to add meters that act like VU meters (for an audio application? Who would want that?!) after over a decade of requests and hundreds of messages, or even the ability to have a forum tag so posters can indicate what platform they’re onn when asking a question, so like us all, you’re just screaming into the void.
