God yes! I do it as a business!!!
I circuit bent my TR505 and I expect the 707 will be similar. A few PCM chips (pretty much looking like the same chip but about four of them in a row) will be the target. These give
Tips:-
-DON'T go anywhere near chips with loads (ie over 32) pins. These are usually RAMs or ROMs and if you screw these, you screw the whole machine up. Nothing will save it.
-If you find loads of bends across a few PCM chips, for god's sake patchbay them. This will let you access any of these bends. See my personal photo album for my 505 patchbay.
-DON'T experiment using your fingers!!! This causes static to build up inside the ICs, killing them. Use a piece of insulated copper wire OR even better, some crocodile clip leads.
For more, I suggest you look

Thanks,

P.S. If anyone wants me to bend anything for them, I will, but I will need some money for the components and the service!!!

Can You provide me some tips & photos of Your 505 with some instructions etc? I don't want to screw my 707

So what in fact is happening when you bend the circuits? Is it just for modifications?

Hmm, depends what sounds you're trying to get. You can get some verrryy nice drum sounds if you start processing all the samples. You can also use vactrols to CV enable it, so you can get CV controlled "hi-hat" loops and stuff. It's great fun IMO.

I heard that it's possible in poly800 to modify the chorus [feedback,depth,lfo] and adding chorus in and VCF in... also that there are possibilities to change the filter 24db-12db
