Confidentiality Agreements for innovative uses of commercial software

I have a startup music business where I can produce, but am not limited to, an entire 18-piece big-band ala Hoyt Curtin ("The Jetsons", "Flintstones" etc.) overnight without any recording expenses to the client -saving them thousands.

I'm considering to hire/ train someone to do what I do under a confidentiality agreement. I use commercial software in a unique way to achieve the above results.

Question: Obviously, I can't patent a key-stroke or software's built-in functionality but how then do I protect my idea while expanding the company? In other words, is it even possible to successfully shape a confidentiality agreement to prevent this person from using my trade secret for any of his own freelance musical productions if it involves commercially available software that I'm using in a way that other's haven't thought of yet?

Thanks much

Your agreement with the individual you have chosen needs to include not only confidentiality provisions but, also, provisions assigning to you everything the individual creates for you, including all intellectual property rights therein.

I see that you are in NY, so non-compete provisions are germane, but I don't have a lot to say about that, because I'm in CA, where non-competes are enforced only under narrowly-defined circumstances.
