4-step 4017 Sequencer

This weeks project is a simple 4-step sequencer based around a 4017 decade counter chip. The basic schematic is based on this circuit, using a 555 timer as a clock source:

I changed it a bit by having the 4017 outputs drive transistors that switch current to the pitch pots (instead of turning on LEDS). [...]
