Hi, Javier, i didn't see your answer before. Sorry, it took so long. I'm very
interested!
The tuning i would like to use is the Fourkey-tuning (from Andy
Newton, Jazzmaan use it).
It can be found here:

(click "continue", choose "Four Key", click continue - then you have it.)
Here is an article about it from Andy:
