Sequencer and VCO prototype

Trying out an inverting Schmitt trigger VCO and a 5 step sequencer using 4017 decade counter. I hooked up the output to my ADSR and VCA. I think I'm happy with both. For my perfboard, I'll turn it into a 10 step sequencer with configurable reset for choosing between 1 and 10 steps. Since the inverting Schmitt trigger comes in packages of 6, I'll change it into multiple on the perfboard.
