This shows six simple experiments that can be performed using my educational synth thing:

1. VCO output
2. Dual VCO output
3. LFO amplitude modulation
4. LFO frequency modulation
5. Envelope generator
6. Envelope generator for pitch

Each experiment is described in more detail here along with links to the design and build information: https://diyelectromusic.com/2024/06/17/educational-diy-synth-thing-part-5/
