E-RM presents with the Polygogo a digital stereo oscillator with unimagined sonic and especially optical possibilities. The core of this tone generator is the novel polygon synthesis, which is based on the complex two-dimensional amplitude shaping of sine waves. The simple operation makes it easy to create new sounds with the Polygogo. The three modes "Infinite Cycling", "Quantized Arrangement" and "OP Ratio" are very different in result and convince with a very wide range of sounds. Two internal modulation sources and the analog wavefolder directly before the outputs additionally enhance the sound spectrum. The Polygogo is also equipped with a hard sync input and an input with attenuator for exponential FM.
