556 Noise Maker (APC) Sequenced by 4017 with 555 clock

An annoying little noise maker/sequencer I've been working on.

how do you plug the sound maker in the clock??

bobby1829387 is right. Sorry for not being more clear. The "clock" is, in fact, and astable 555 circuit. It tells the sequencer when to switch to the next step. So it's not actually plugged into the soundmaker. 555=>sequencer (4017)=>APC. Hope that makes sense.

Hey ok now it works but it only steps through 2 steps. Dont know whats wrong with it. i used different potis on every step is this the problem? And why is there a resistor between cv out and the apc?? hmm

Thank you

[robfrosty]

@lastkidontheblock if it only steps through two steps you need to change the pin you are reseting to on the 4017. The 4017 offers you 1 through 10 steps. I'll have to check on that resistor on the cv out... not sure haha

Nice ! What pin does the 4017 output's cv out connect to on the APC? Thanks .

[robfrosty]

4017 goes to 556 via pin 2 - after the resistor. Let me know if you need help with any other connections : )

[rikkeeked]

Sounds like dial-up connection, cool! =)

junk!

1:07 nice sound :D

[bobby1829387]

@Greenselves Is isn't an actual clock, the clock he is referring to is the speed that the 555 chip turns it on and off at.

Damn dude you need to sell this shit. I'd buy it.

[allowishus664]

which resistor? what schematic are you using?

nice work!
