EDIT PAGE – Oscillator Synth Hard-Sync

 

 

Hard Sync was a feature on some analog synthesizers, which gave the timbre a "throaty" dipthong type of sonic characteristic when swept. Hard Sync was popularized on synthesizers like the Prophet Five and the early Oberheim synthesizers for more metallic and aggressive timbre, especially useful for lead sounds. Hard Sync is achieved by using two oscillators, one which is the ‘master’ and the other the ‘slave.  The slave is forced to restart its waveform when hard-synced with the master oscillator and the master controls the pitch.  So any changes in the slave oscillator’s pitch don’t change the pitch of the master, they change the overtones and harmonic structure instead.

In the past, an oscillator would need to be sacrificed to get the hard-sync effect, but Omnisphere has a hidden, dedicated oscillator just for hard-sync.  The hard-sync oscillator becomes the slave and the Oscillator’s waveform is the master.

 

NOISE waveform only - HARD SYNC control acts as a stereo width control that begins with monaural setting at the minimum setting and gradually spreads the noise into both right and left channels towards the maximum setting.
