Finished Pieces

yamaha PS3

    I couldn’t find a whole lot of glitched out mods on this piece but I did find some cool utilitarian features. Then I added an echo circuit for good measure.
    The drum sounds (bass, hit hat and bongo) can each be routed out separately from the main synth IC (see schematics below) along with chord accompaniment “hi” and “low”.
    I built a simple mixer circuit for the 6 parts so that I could give each it’s own dedicated volume control.
    Then I patched the mixed signal through the echo circuit. I’ve also added a glitch knob and glitch touch sensors.


    Sorry, no sound files for this piece.

      impressive but how do you figure the outputs from the IC? Do you have the service manual? Anyways, used to live in Troy, near RPI (14th st, to be exact).

      I just connected a jumper wire to the input of the output amp and used that jumper to poke around on the main sound IC. It didn’t take long to find the isolated sounds. Were you an RPI student?

      Wow, I love the projects you’ve done! I’m just starting out. Hopefully, one of the capacitors is the reason the long stored Yamaha PS (r) 3 is no longer working…but i could only buy two of the 6 possible capacitors at the local electronics store…is it’s one of the others, any advice as to where i could get the proprietary capacitors, a new circuit board or whatever it takes to get the PS3 operational again?? I think very slowly unfortunately..
