A synthesizer voice is an individual audio circuit path in a synthesizer which produces an individual sound.
Signal flow
Even with multiple oscillators, a typical monophonic synthesizer has a single voice and only one key at a time can be used to sound a note. On a polyphonic synthesizer, as many keys will sound simultaneously as the instrument has voices.[1]
The simplest standard voice is made up of a VCO, a VCF, a VCA and the envelope generator to give the note timbre and dynamics (changes in loudness). In a polyphonic synthesizer, each voice is a parallel signal path with its own oscillator, filter and amplifier. A paraphonic synthesizer plays several notes at once, however they all go to a single filter.[1][2][3]
Sometimes voice is also used to refer to a preset instrument-like sound.[1][4]
Rather than have a voice for each key, a polyphonic synth's keyboard will use voice allocation to allocate a voice to whichever key is pressed. Exceeding the maximum polyphony results in voices cutting out abruptly.[4]
