- First things first : Original circuit schematic can be found in this post at electro-music.com
- I made a couple of modifications that worked for my Baby-10 sequencer project
- The modified circuit was breadboarded and worked like a charm 👍
- I replaced the TL072 Op-Amp with an LM358 which resulted in a less noisy output signal.
- I replaced the 1uF electrolytic capacitor C1 for a 0.1 uF K63 film capacitor for better and well defined gliding voltage-range output.
- Check out the modified circuit
- The only thing I can brag for is the actual PCB that I crafted myself as a personal learning tutorial on DIY Layout Creator
