It could be cool but I have no such plans.
I like the idea of Aalto working on an iPad, I really do. But as far as I can tell, people are not willing to pay enough money for iPad apps to support my developing one. That's my current impression and I am open to suggestions.
There are iPad apps that cost much, but they are dedicated for professional applications. Mostly related to film industry.
Myself I'm happy with my Lemur interface to control Aalto on a computer. Although in future I might buy a more powerful iPad (currently the most powerful iPad I own is 4th generation). In this case a software like Aalto might run well on such an iDevice with enough CPU power.
I think this is something to think about in the future. Maybe in the near future, who knows.
The developers forum suggested it is trivial addition as it is still a full AU as Aalto/Kaivo already are. Perhaps this could be paid upgrade for those who already own the full Aalto/Kaivo rather than an App style purchase price.
But I take your point you have enough on your plate. Good luck with Virta.
It would be a cool thing to have, so I'll stay tuned for info. I'm not up on all of Apple's latest. I do know that Aalto would have to be recompiled for ARM at the very least.
I like the idea of it as an add-on to the full version.
Look forward to seeing how this pans out. All the best. S
