Brian Green has put together a free sample pack (Mediafire link) of circuit-bent sounds from a Yamaha PSS-7:
I decided tonight that i would try to do some bending stuff with my pss-7 again since i have only messed with it once and never really did much, after awhile of messing around i found 3 contact points that would basically cause the unit to freak out in a different way every time.
The reason i call it the mystery bend is you never know what your going to get sometimes it will loop, other times it will be a Fx sound and it will fade all on its own other times it just does what ever it wants its a mystery, Hence the name.
After while of messing around with it i decided it would be a good idea to make some loops out of the glitches because i could not recreate the sounds it was making and i just decided to make a little sample pack which can be downloaded below.

Please Note: All samples in this pack are original and royalty-free, i just ask if you use them in something please send me a link to check out.
More example videos of the bent PSS-7 are available on Green’s site. Green is also looking for people interested in a circuit-bending collaboration.
