8 Step Sequencer

First 'Real' Post...

Made an 8 Step Sequencer with a two 555 timers and a 4017 decade divider.
I used the first timer as a low frequency astable oscillator. I could make it a 10 step sequencer, but I thought 8 would be more rhythmic (think about time signatures).
Then, I used the other two timers to make an Atari Punk Console (Stepped Tone Generator). 


If you want the schematic, google for 

  • baby 10 step sequencer
  • atari punk console

Connect the sequencer's CV output to the Atari Punk Console's first oscillator's CV input (pin 5)*
To make the 10 step to an 8 step, connect the 4017's Q8 to Reset.

*Was that too hard? I'll be making a schematic soon.
