Circuit-bending sound and timing of keyboard(YAMAHA PSR-185)

I’m playing around with the sound chip, which also seems to have a big effect on keeping the different tracks in sync (drums, bass,

    2. dude you should use a little resistor when you shortcut pins. to Avoid broke your synth’s Cpu and ics

    3. i bent resistors together on mine and it temporarily broke :(

    4. Looks like the chips on the PSS. The main CPU crashes a lot :/

    5. Add a reset button.
    P.s I was bending??? mine with LOW batteries…CRAAAP!
    I will get NEW batteries and try again…

    6. I may BEND mine, I have been thinking about it.
    YEAH!

    10. Yeah. DOnt wanna sound like a douche, but shouldnt you not be foolin around with stuff like that lol

    12. But it’s useful using the multi-meter, because on certain modes (like voltage) it just seems to ‘connect’ the leads a little, while others (like resistance) actually gives off a little power through the leads. Also as you can probably see, the metal end of the leads fits perfectly between the terminals on the chip.

    13. Yeah, it would be easier, but I don’t have any. What I’m using is just the cords from my multi-meter, since I was originally measuring how many volts there were between places so I wouldn’t blow an LED (or speaker) if I connected one.

    14. hey i want to start doing this but what are/where do you connect those chords? wouldnt it be easier to get clips so you can keep the sound without having to hold the cords?

    15. Yeah, though overall it wasn’t a very good bend :( Very unpredictable.

    16. I’ve had that PSR-185 for about 9 years so it was well due for a bending. :P

    17. I haven’t seen the PSS-6, I just looked it up and it looks similar to a certain little Casio one I had many years ago.
    That could also produce some very weird noises if you fiddled with the switch or the batteries while it was on, far beyond pulsing noise.
    More like buzzing and squealing. :P

    18. Well, there were about 6 different sounds I could access ‘at will’ (once I’d got it into that strange frozen-but-not-silent mode).

    The rest were all really random and uncontrollable, nearly all the bends you saw were just between 6 or so pins on that sound chip. The only 2 bends I found which always worked were the mess-up-percussion and mess-up-timings ones (in my opinion they’re the most interesting too).

    19. How many bends did you find in the end?
    I’m tempted to bend my PSR 38, but it has some nice analogue sounds – so if it’s lost I’m buggered.

    20. Wow, we used to get that static echo with the PSS-6 (I think that is what it is called). You could trigger it by fiddling with the power switch.

Tell me what you're thinking...
