Thank you everyone for the congratulations! I'm very happy, I work very hard and I always feel I deserve a big present once every two/three years. Next one will be the successor of the Psr s910 which might be arriving to Argentina in 2015 haha. Some people may think there are too many keys, that's true but I see this pile of keyboards as a work of art. It entertains me thinking how to build this "organ" and connect the parts among them.

Frans: it will be easier to order one instead of searching an Ec5 on E Bay. In my country we have "Mercado Libre" the latin american version of EBay and we have different products

Rikki: You are right the styles are quite different so I will save the Pa500 styles before I sell it. May be I ask you later for some of your great work, specially for extra pads that can make a style sound quite different

Duan O: Thank you!! that's what I needed. That schematic explains what I thought, but there is a little variation since pin Nº 3 is ground. I could make some buttons beneath the middle keyboard instead of a pedal

Stephen: your review on the pa3x got me very enthusiastic and I decided to buy it right away.

Jez: and more keys if you count the Pa500 which is on sale and the Ensoniq ws inside the closet!!
