Unconvetinal brass instrument developed at the Electronic Music and Musical Production course (ESART - School of Applied Arts of the Polytechnic Institute of Castelo Branco, Portugal, 2009).

Inspired by Adolph Sax's intruments with multiple bells, this instrument has a total of six tube ends with different lengths than are controlled through water valves. Sound can be spatialized according to each tube's direction. When more than one output tube is open the air column is shifted to the tube with the least impedance to the input frequency.
