K49 internals

[Zurechial]

I'm planning to buy a K49 and cannibalise it for parts for a DIY midi-controller project, but I'm just wondering if anyone here has an idea of what the internals of the K49 are like, from opening it up before, or does anyone have a service manual or schematics for it?

I chose the K49 specifically because I'm hoping that the key-action of it will be similar to my Triton Extreme (61-key) and it has some nice modulation controls that I want to try and make use of in my controller, too.

Thanks in advance to anyone who can give me an idea of what the internals will be like to get at or dismantle.
