Great stuff. I can see this being very useful.
Any suggestions for modifying an external sound source using a mic? Kind of like a vocoder, but but just using the level to control a filter? |

Well you can use it as a clock to other circuitry and then your other circuitry will also be voice modulated, that would be the main use. I found that doing so works if you keep the frequency unmodified, but as you divide down the frequency the voice signal fades. This makes sense as binary dividers have the feature of removing duty cycle variations.
Also it opens up the possibility of using a switched capacitor filter, something which I have not seen discussed here. Perhaps we should look into those circuits.

Great circuit! Thank you!
I was wondering how can I use the output of a guitar instead of the microphone.
I am thinking of removing the 0.1 capacitor and the 10K resistor of the mic and connecting the guitar. Is it possible? |

Only one way to find out!
I'd suspect it would 'modulate' but I wouldn't expect much musical correlation, but perhaps i'm wrong. You could always just mic an amp, no? _________________ home made noise and electronic ill-logic |

This is interesting. I've been trying to decide whether to use Schmitt trigger oscillators or 555's to make a drone synth, this scores a point in favour of the Schmitt trigger oscillators. Will need to try it out. |

Hi, I just popped in after a Christmas hiatus and I'm pleasantly surprised to rediscover this post. Right now I'm 3D printing some "paper" airplanes (they are plastic versions of an iconic 1970's paper airplane).
Then there is the remaining list of projects. Long story short, I'm reexamining the list of projects and I'd like to add one music project to the list. This circuit could be the one.
I like breadboarding quite a lot as regular posters and readers may recall. Now with 3D printing I can make custom breadboards. Also I've thought of delving into the freeform art with a 3D printed accessory object. All very interesting. Does anyone have interest in this direction?
