I am integrating the 4046 module into a larger lunetta synth - so only square waves will come in, do you think the 4049/4069 will add something to the sound even though the signal is squared in the first place anyways?
of course I could just test this out myself, I might anyhow but I don't see how you could "square up" a signal which is already squared... |
I've built my first tracker just like it is in the Nic Collins book; with the 4049 as preamp. Realistically, it's not essential in our lunetta since most of the stuff we will push through the 4046 will already be square/square-ish. My more recent tracker builds don't use the 4049 and work just as well as my first one.
That said, I have heard slight variation in sound when I sweep the 4049 gain pot. Adds a bit of hair to the sound but not a must build .
With the 4049 and say a 1/4 jack wired to accept input from a guitar, mic, etc., the addition of non square signals can be accomplished. (I need to diagram that sentence). _________________ Zontar Prevails! |

Yeah, I've got my own copy of Handmade Electronic Music
It's a brilliant idea though and included in my future build no doubt! _________________ www.dogenigt.com

I am having a little headache about something here.
I want to have diodes on my 40106 pulse outputs for mixing but when I connect this output through the diode to the input of the 4046 it doesn't work. It's like there's no input.
I could mix with resistors but then the voltage drops from my reference HIGH doesn't it? (9V in my case) _________________ www.dogenigt.com

Try a 100K resistor to GROUND after the diode. See if that works. |

Thanks guys! I solved this buy running the "dioded" signal through a schmitt trigger (40106) _________________ www.dogenigt.com

CD4046 |

Output 1 sounds amazing. Output 2 sounds great too but seems to respond to the negative edge of the pulse. great delay effect!
Here I am 4 years later. Thank you guys for some amazing ideas.

did anyone try to listen to the output of pin1 and pin2 on the cd4046?
Cause I made some similar circuits like the pitchtracker and if you are lucky you get to here this weird bitcrushing-like sound on these outputs. |

Still one of my favorite chips to work with. Now, back to my crypt... _________________ Zontar Prevails! |
