  • that fucking doll behind is scare me xD.and that music is a blend of horror like frankenstein.

  • Older video game systems like the Atari and the 8 bit Nintendo used square waves to generate music. The wave goes from full positive to full negative voltage (read: the speaker cone goes all the way out, then all the way in) at the frequency of the musical note to be played.

  • Someone know how to add a "trigger level" control in a time base?

  • no trigger...

    sorry, too easy to connect an amplifier to a deflection coil...

  • This is only because they did a note sequence with one tone that remeber some of the games, not relation to the shape of the wave... The Sound Processor in the NES ( 8 bit nintendo ) have triangular wave, white noise generator, and other wave patterns...

  • Atari and Nintendo may have used square waves to generate music, but I hear a similar sound and see sine waves. Just out of curiosity, where did you get that information?

  • At 0:35 it starts to sound kinda like the music in early video games like Atari.

  • You need a triggering circuit
