Good decision - and you will have a lot of fun too.

HP has integrated Leap Motion in their ENVY17 laptop:

Imagine doing this on the kronos with leap motion, it would be great.

And this gave me the idea to do it on the kronos using the vector joystick just to gave more expressivity to the orchestral parts....is it possible?

Thanks for sharing - it's impressive and looks like conducting a symphonic orchestra, which responds to the motions.

With Leap Motion & Gecko you can do the same thing at the Kronos - given you have one and a computer connectec to the keyboard. So far I used Leap Motion to control various Kronos synth parameters, but the volume sliders of a combi should allow to link them to the corresponding midi channels. There is only not such thing as midi learn in the Kronos, but Gecko allows direct input of CC numbers.

But I fear, the use of a joystick instead of Leap Motion will not do, to achieve a similar man-instrument interface. A joystick does not support the same degrees of freedom (I counted at least 4 in the video, 3D plus roll of the hand) a stick allows for two only.

A bit OT, yesterday I decided to try it with the joystick, it's not exactly the same but had a great result.
Basically I programmed a combi and modified the volumes on the joystick for each instrument and putting timpani in the backgroung with high velocity....I will post soon a video but it's really a good result in my opinion, and the merge between strings, flutes, brass and choir is very smooth, I love it.

Just read a thread on this over at KVR, but not seeing as many applications as you all are talking about. I was wondering if anyone uses this with softsynths? It looks like it might be a good way to control x-y controls on Alchemy and Zebra. Would it be better to have two for that?

Exactly this works fine...

In Zebra you can modulate more than on of the x-y controls simultaneously - you feel like a director of an orchestra, waving your hands and your instrument follows in so many ways - provided you have the sound-modulation prepared accordingly.

This is what you need.

1) One unit of the leap motion controller (comes with driver and Airspace software environment)
2) one licence of the Airspace-Plug-In Geco (it's an app in the Airspace environment to be purchased seperately and to be downloaded after Airspace is installed)
3) install driver, Airspace, Geco
4) hook up your instrument and ready to rock.

It's truly plug and play.

Geco generates midi CC-data on gesture, that you perform in the field of view of Leap Motion. CC-data and midi channels can be defined freely. There is also an easy process for midi-learn, which helps to set up synth specific Geco setups quickly - no engineering degree needed

I would start with one unit. It recognises two hands (left and right). IMHO it should be enough for most and also complicated modulation scenarios. You can control more than one of the Zebra x-y with one unit. A second is definitely not required.

I also thought about having more devices, like two units with perpendicular FoV-axis. AFAIK each degree of freedom can be used for one CC only. With two devices the same movement could be used to generate two sets of CCs with different purpose. But at the end of the day ... wouldn't this become quite complicated to handle?
