“Hard Sync” Oscillators in Reaktor 6 Primary

Creating retro sounds with hard-synced oscillators in Reaktor 6 Primary.

“Hard sync” is synthesis technique that uses two oscillators: when one oscillator (the “leader”) finishes a cycle, it resets the period of the other oscillator (the “follower”), creating a period at the frequency of the leader, but a timbre from the incomplete cycles of the follower.

This is a really easy way to create original, complex sounds, using just two oscillators.

I say “1980s”, here but check out this sound in the Cars 1979 hit, “Let’s Go” (played on a Prophet-5 Synthesizer).
