This module outputs an S-Poly chord signal selected by one of the 23 preset chord buttons.
The LEDs indicate the intervallic relationships of the notes that the chord is built from. So for instance the LEDs beneath the “3” label indicate major and minor thirds.
The root of the chord is controlled by the pitch voltage fed into ROOT IN socket. This voltage would often be supplied by a scale module.
