does anyone have schematics for a sine/synth filter or a saw lead or square wave? i am interested in building one... i have experience building/ cusomising distortion circuits....

When you say a sine filter, do you mean the LFO? How come you'd be putting an LFO in a distortion? Or an oscillator even.... -Colin |

why the hell shouldnt i? EXPERIMENT is what i do..... any ways this "total sonic annihilation", how exactly does it work? i know what it does, but i want to know how, for later reference. i have already built one using send/return/inout jacks, a dpdt, and momentary spst for throwing in the feed back and plugging the fuck out...... thank you and good night...

First off, could you explain what you mean by a "sine filter"? Filter's don't have wavefoms. The total sonic annihilation sends the output of a circuit back into it, making it feedback. -Colin |

i meant a filter to change the waveform, in other words, a processor. sorry for the mix up.

Converting to square is the easiest, try amplifying a signal, assymetrical clipping it, then put it into a hex inverting schmidt trigger to get the ramps perfect. Then it get's complicated  I find it's probably just easier to build different oscillators for the waveform you want. -Colin |

i i have modded a fuzz face to sond like a square wave , but i wanna know how to get just the wave transformer....

Well, a square wave would most easily be made by clipping your signal assymetrically, and then putting it through a schmidt trigger to fix the slope. It will sound almost exactly like your standard old fuzz face, that's what a lot of fuzz's do. If you want to get it to be different waveforms, go check out some websites out there... on the modular synth pages. I have ideas for a waveform converter. Keep in mind that the guitar signal, normally, is reasonably sinosudal. Then again, when you make it square, it loses a lot of harmonics... so it would basically be a "boring" sounding guitar  ! -Colin |

A  sin wave has no harmonic content, and sounds booooring, think hearing test at the doctors office. |

Is the difference then that a sine waves harmonics are seperate waveforms and a square waves are "included" in a single waveform? -Colin |

Isnt it that any pure sine wave has no harmonic content. Eg what they play for the hearing test is a pure sine wave. In the case of a square wave the harmoincs are produced because of the rapid rise in current. The faster the rise in current the more harmonic content.

In the case of a square wave the harmoincs are produced because of the rapid rise in current. The faster the rise in current the more harmonic content. Pure sine waves have only the fundamental frequency, where, if I remember correctly square waves have odd harmonics as well. To get near a sine wave, but not exactly, you can use a steep low pass filter tuned just right. This won't give you a strictly pure sine because an input signal would probably be a very complex wave form, with a set frequency filter your lowest frequency inputs may still have some harmonics, and your higher frequency might be totally cut if the filter cutoff is below that of the fundamental. In other words there would definitely be a sweet spot for this type of setup, and you would need to tune it to find your sweet spot. |

That makes sense. I guess I wasn't putting two and two together before.

-Colin I'd say everyone was going in the right direction... The math and everything of waves is still way over my head!  |
