Hi, thanks to Santa Claus I have a brand new s4 mk2 controller and it pretty awesome to start with. I've been using traitor for a long time but only the software with no other external device. I have a Yamaha psr e313 digital piano with has a midi in and out route, I like to use a lot of samples and the s4 only allows me to use around 8 and no more, therefore my question is if it's possible to change the keyboard of the piano with some samples and how shall I do this, in pretty new to this midi and mapping world and I will appreciate any type of help!

Thanks if forehand
