Paraphonic

Paraphony is a term used in musical vernacular to refer to consonances which rely upon intervals of fifths and fourths. This terminology can be traced to ancient Greece and sources such as Theon of Smyrna.

Paraphonic is used to describe an implementation of polyphonic synthesizers where all the notes played share part the electronic signal path. For example they may share a single filter or an Envelope generator.

The Korg Poly-800 had 8 oscillators and could produce 8 voices but had just one filter circuit shared by all the voices. Other examples include the Moog Sub 37, the Roland RS-202 string synthesizer, and other early synthesizer when true independent signal paths were expensive to produce.
