Internet Co. F-REX (Digital produkt)

F-REX can analyze the sound that's being played in real time into the three parameters 'Gain', 'Frequency' and 'Panning' and graphically visualize them.
You can control independently the inside and the outside area of the specific part focused by panning and frequency. You can apply effects (compressor and reverb) to inside and the outside area and adjust volume and panning intuitively.
