Hi Steve,
Awesome synth. I have been listening to your youtube 3 hour Elite session and it's very interesting. Just wonder if it is ever a possibility that you will do some synth or drum machine coding for the IOS platform. That would be super cool. I know the price point isn't stellar but even a scaled down version of Serum would be kick-ass.
I'm afraid this is unlikely due to a number of factors. I don't make music with iOS, I don't have much iOS dev experience beyond a basic app, I don't have the time to invest even to experiment with that.
I wouldn't be opposed to partnering with someone to port it, but that person just isn't going to be me for aforementioned reasons. Quality scaled down would be a necessity and that isn't appealing (although I think it could be compromised decently). You may not be interested but a Microsoft Surface or similar would be a way to use Serum on tablet/portable currently.
