The Electro-Harmonix HOG2 carries many of the same specs as the the original HOG (Harmonic Octave Generator), which can generate 10 polyphonic voices ranging from two octaves below to four above the instrument’s pitch, and adds new algorithms to improve the quality of the tones, as well as the Freeze function, MIDI control over all parameters and pre-sets, Master Volume, and save/recall up to 100 preset programs with the optional foot controller (versus six with the original).
