Both share the same pinouts therefore they can be used to replace each other. The difference is that the 4016 has a higher internal resistance across the switch. This means a loss of signal fidelity. The 4016 is really meant for other types of switching and is not optimized for audio switching. The 4066 is much better for audio switching."

Yeah, that's the weird thing though - the oscillators (audio) are done using the 4016, and the modulation (mostly not audio) are done with the 4066!
