bending a casio PT-20 or a PT-30

[zigo_bzh]

Hi everybody,
  I find a PT-20 for nothing and i want to bending it. I search everywhere to find schema to help me. But i find nothing. Anyone have suggestion to bending the casio PT-20?

I'm sorry about my language : i'm french... I hope you can understand me.

Moreover I will have a PT-30, and it will be the same problem.

  Thanks for answering

Circuit bending is all about discovery, not just reading schematics people put online.  Just open it up, poke around and see what you find.  If not having schematics is a "problem" then you shouldn't be circuit bending..

I worked a little on a PT-30 and didn't find too much.  If you're into doing some resistor substitution you can get some small effects with the drums.
