'''Oscillator sync''' is a feature in some [[synthesizer]]s with two or more [[Voltage-controlled oscillator|VCO]]s, [[digitally-controlled oscillator|DCO]]s, or "virtual" oscillators. As one [[oscillator]] finishes a cycle, it resets the period of another oscillator, forcing the latter to have the same [[frequency|base frequency]]. This can produce a [[harmonics|harmonically]] rich sound, the [[timbre]] of which can be altered by varying the synced oscillator's frequency. A synced oscillator that resets other oscillator(s) is called the leader; the oscillators which it resets are called followers. There are two common forms of oscillator sync which appear on synthesizers: Hard Sync and Soft Sync. According to ''[[Sound on Sound]]'' journalist Gordon Reid, oscillator sync is "one of the least understood facilities on any synthesizer".<ref>Reid, Gordon (November 2002).[http://www.soundonsound.com/sos/nov02/articles/synthsecrets1102.asp "Synth Secrets: Synthesizing Acoustic Pianos On The Roland JX10"].
