A demonstration of the famous Thomas Henry VCO-555. This is an amazing sounding VCO, especially if you use the Exponential FM function as you will hear. I put the VCO output through the Steiner-Parker filter which sounds awesome. At the end I compare it with the Digisound-80 VCO which I think is also a great VCO but it only has a linear FM input so the comparison isn't really fair.
You can find complete instructions on how to build the VCO-555 on stripboard, on my website:
