I got a question already :)  Could a button on the x-touch take the role as "shift" instead of a pedal to enable using the VPC keyboard to trigger shortcuts in the same way as if using the pedal? Just curious. I really like the idea of having all 88 keys available for shortcuts, alreadystarted thinking about which ones etc :) 

Yes, that will work (just tested). But you loose one complete button on Mini... And each button does many nice things
 
One small warning. I have written the implementation is "perfect" is Sonar. I forgot one bug. You can only switch modes after you release all keys, otherwise you get "hanging" notes.
(I have just implemented the whole idea in another DAW, but without this bug)

Hi azslow3, just got teh device home and hoocked it up. Just played with it for an hour or so but man, why the hell did I not get something like this years ago?!  It works just like you said and I can tell it will do wonders for my workflow AND fits perfectly on my VPC1 without the need to stands etc.  I will play with it and might come back with questions but for now I love it :) 
 
Great stuff, thanks!
