E-RM Polygogo Stereo Polygonal Oscillator

E-RM's Polygogo is a stereo Eurorack oscillator that employs Polygonal Synthesis, originally invented at E-RM by Maximilian Rest and Christoph Hohnerlein. It is based on complex two dimensional amplitude shaping of sine waves, combined with internal modulation sources and a new type of wave folder.

The main algorithmic core is carried out on a digital processor to guarantee absolute frequency stability for internal modulations. The stereo wave-overflow output is classic analog circuitry, to retain unprecedented crispness and an open sound.

Its “single knob – single function” interface, created in collaboration with instrument designer Tatsuya Takahashi, makes the polygogo not only a terrific live performance synthesizer, but a great tool for meticulous sound design as well – no menus involved.
