DIY analogue synth project Part 5b Hard Sync Testing with CV Keyboard control (Direct Audio)

In this video I test the Hard Sync circuit I put together a while back in Part 5 ,(I absolutely love the sound of Oscillator sync). I have done some small modifications to the circuit and i now have an adjustable pulse coming from the output of a dedicated op amp linked to VCO 2 which in this case is the master oscillator and frequency.
