Endless Series – Review

EndlessSeries

Endless Series is a unique audio tool from Oli Larkin. It is tough to describe it in a single sentence. The description on the ‘box’ says “Shepard/Risset Tone Modulation”, which only scratches the surface of what this plugin is capable of.

What are Shepard/Risset tones?

From the manual:

Endless Series is an experimental effect/tone generator based on the auditory illusion known as The “Shepard Tone/Scale” after Roger N. Shepard who discovered it in the 1960s. Shepard demonstrated that using basic additive synthesis principles it’s possible to create the illusion of a continuously rising or descending chromatic scale. Although Shepard’s scale appears as if it is constantly moving in one direction, in fact, after twelve steps it returns to where it started.

The composer Jean-Claude Risset did further work with circular pitch illusions and created a version based on a glissando rather than a scale (sometimes known as a Risset-Tone), which he used in several compositions.

So, what does it do?

Endless Series synthesises Shepard/Risset tones and most importantly allows you to change and modulate the parameters that affect the synthesises of these tones = lots of cool design options! More importantly, it can also modulate an audio input signal using different modulation modes (more below). The plugin might not make sense on first run, but the manual is quite extensive and very clear.
