I enquired with Harrison about multitouch a few months ago and they said the main issue was lack of standard for the mac platform.
Since OS X doesn't natively support multitouch and there are no Macs with multitouch, they are reluctant to go into it just yet.
It is definitely something they're interested in doing, but they obviously feel the time isn't quite right.
I told them there are many people with Raven and DTouch systems on Mac and that there are DAWs that offer multitouch on the mac platform.
On multitouch vs. hardware:
I think multitouch is the future, just like ProTools was the future.
For most people, multitouch will be enough.
If you want hardware and are willing to pay the extra cash, you can marry hardware controllers to multitouch, but it will be pricy (luxury item) and just like the last twenty years, there will be varying succes with hardware controllers. (some functions work great, some are decidedly cumbersome).
Of course, the same can be said for multitouch, but the bang per buck ratio of touch screens are already so ridiculously good compared to hardware controllers, that it can only get better. It's pretty much a non issue.
To be honest, hardware controllers didn't get that much better over the last 20 years, nor did they get much cheaper.
They are a luxury item, a must for some workflows but I would say they are must for a minute minority. I think that whether YOU agree with that does not necessarily have much relation with whether it's true. We like to fool ourselves and/or keep doing what we're used to doing. Telling ourselves this is the way we NEED to work, doesn't ALWAYS mean that's true.
I'm not saying there's no engineers who NEED faders, I'm saying at least a portion of the engineers who say they need them, don't.
It's going to better from here on out.
We've waited for about two decades for hardware controllers to become what we want and it just didn't happen.
A modular world where you control everything with touch but can add hardware modules (like faders and pots) for the things you really prefer on hardware will be cool.
Personally I'm not sure I'll go back to more than one physical fader (if at all) but I can see people with a bank of 32 physical faders, maybe a single strip of rotaries and bunch of touchscreens behind it.
Harrison could be cool in this world, although I need a lot of flexibility with bussing, consecutive buses etc.
A simple 8bus tracking console is fine for most music folks, but not for me or a lot post guys I'd assume.
Exiting times though.
