Achordion is a wavetable oscillator and chord generator that provides 37 wavetables divided into 4 banks (Perfect, Harsh, Soft and Tines) with the ability to smoothly transition between them.

With up to 18 simultaneous voices, Achordion can produce sub-octaves and duplicated tones as well as standard chords. There are four modes of play are available in the Achordian – single tone, selection of 18 standard chords (fifth, seventh and ninth), arpeggios, and intervals. All notes are quantized to a configurable scale along with the 1V/oct inputs, so any scale can be played on a controller.

Two melodic lines can be played at the same time, each controlled by an independent 1V/oct input. Each melody can be sent to it’s own separate output, enabling each line to be processed by a different effect chain. A display consisting of 8 LEDs is used to make dialling of parameters easier.

From smooth lush pads to dense walls of sound, Achordion encourages the exploration of different scales and intervals. Even if you don’t know any music theory, this module will do all the harmonic maths for you, and all left for you to do is use your intuition.
