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:
- 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.
