Hello all i hope someone or everyone can help!!
Ive just purchesed a casio MT 500 and a yamaha PSS 780,
Ive never ever done any circuit bending but im a electrician and have dabbled in electronics at college so im game for a go....
Ive seen a few youtube videos of how to and they advise to use a wet finger!!!! and short things out (whilst not on mains power obviously!!)
Can anyone give me any tips on these machines above basically im looking at where to start!! and if anyone has ever bent these machines before!!
I really hope you can help me i love the idea of this form of noise experimentation and cant wait to get started!!
thanks

The PSS780 probably uses a readily-identifiable Yamaha OPL-series chip, possibly a YM3812. That's always a fun place to start. Mess around with the data lines while changing patches.
you should check out http://weltenschule.de/TableHooters/instruments.html i think both of those keyboards are on there.
Brilliant stuff thanks for the tips!! call me stupid but when you say data lines i assume you mean the pins on the chip??????
i am totally new to this but as i mention well up for a challenge!!
ive got a yamaha rx17 to mess with too...
i got the casio and yamaha keyboards for 26 quid the pair!!! bargin huh!!!
id love to chat to someone that has actually bent one of these keyboards!!
getting excited about this new hobby of mine!

Since you are far from the only newb here, why not document the quest here (and of course post the pics and sounds). This way we can all enjoy/participate and all that.
Just a suggestion.

Look the chip up on Google, and search for a datasheet. They communicate with the processor via an 8-bit parallel port. Messing with that can make it do some pretty odd things.
