Requiem For a Keyboard

the circuit bending experiment i’ve embarked on has suffered its first casualty: my 1987 yamaha pss 30 keyboard. it’s the instrument that i dismantled to get feedback loops, distortion effects, and various alien sounds. my friends at associated radio told me to administer last rites. apparently i fried the audio chip. fortunately there is another keyboard ready to go under the soldering iron: the bontempi system 5 at808.
