I'll guess that you're way more into the NI ecosystem than I am, which is why you'd like to be optimistic about the changed-hands company's future prospects and I don't really care. The problem with how the uncertainty in my mind and business as usual viewpoint in your mind affects us as users and potential users of NI KK mkIII controller keyboards with S1/FSP is that NI was already villainized by its own users for taking ridiculously long to implement the functionality they claim possible with essentially a computer inside the mkIII boards. The pace of progress was glacial even before the big insolvency announcement. If I were you, I'd like to remain optimistic too.I'm not sure why you feel that Native Instruments under InMusic is less secure than it was under Francisco. The whole point of the transfer of ownership was to remove its debt and give it a secure future in an organisation whose only focus is music! However, you're right that a few deals have begun to appear - I've just seen it for £679 at thedjshop.co.uk, which is a very good price indeed.
Anyhow to make up for this departure I'll testify that it was completely painless to use an Arturia Keylab 61 mkII with S1 at the same time as a Korg M3 keyboard. Took zero extra effort other than the initial setup of both boards.
