Amazing ! I would like this ink to print templates for vArranger !

Every one his own personal temlpate with the feature he need the most

There are a few programs that allow just this on an ipad... Then you could create the surface you like and use ipad to controll Varranger....

Do you have some examples?

I am using Lemur, but also own touchosc, which is quite good to... I use them to create touch interfaces for mainstage on my mac, but its just as good possible to use them with Varranger...
