In the late eighties & early nineties Herman Gillis was guitar player & producer in the Belgian music scene. His formerly contributed also in Poesie Noire. On this site you can also find a list on recordings that Herman wrote, or contributed to as producer (under his artist name “Sherman”). The first Filterbanks that were marketed in 1996 were hand-built, and only 40 pieces were made. These prototypes did not have MIDI. At the same time, the designer Herman Gillis also made 9 Sherman Chaosbanks. After a lot of people asked for more Filterbanks and Chaosbanks, Herman decided to update the prototype model of the Filterbank with MIDI and at that time, he added even more features to the box. This is how he came to the one and only MIDI Sherman Filterbank. In 1997, about 500 Sherman Filterbanks were sold, merely in the United Kingdom (London), Belgium, Japan and the Netherlands.
