The Step Father

The Step Father is my DIY desktop synth project. A little something I am building for myself as I have always wanted to dip my toes into the world of modular synth building but don’t have the space for a large setup. This seemed like a good way to build something that could make neat sounds and also interface with more modular synth stuff later on. Right now, it is a fun standalone noise maker.

The Step Father features:

The Step Father - 8 step desktop synth
  • LFO – pretty standard 40106 oscillator based on info I first learned about here
  • 8-Step Sequencer – almost the classic 4017 Baby 8 – link to the first article I read on it here
    • CV out
    • CV pulse out per step
    • Stop/Start switch
  • Dual Wave VCO – interesting LM358 VCO I previously wrote about
    • Wave type mixer
    • Mixed output
    • Mute switch
    • Playable with pushbuttons
  • 8x Mini Space Rocker circuits – more on these later..
    • Wired one per step
    • Mute switch
    • Playable with pushbuttons
  • Delay – PT2399 delay based on the Rebote 2.5
    • Pushbutton for infinite delay feedback
    • Mod switch and feedback control pot
  • JAN6418 mini-tube amp on the output, info here

I tried to include links to the articles I sourced the underlying info from, or to places on this site where further info can be read.

I still have a ton of things I would like to add like separate outs for each wave type, as well as an out for the LFO, etc. More documentation to follow as the build continues.
