The weird looking mutantrumpet is a hybrid instrument invented by Ben Neill in the beginning of the 1990’s, the electro-acoustic-visual trumpet contains three bells, two sets of valves (that is, six valves instead of three) and a trombone slide. In the mouthpiece there is a pickup that converts the sound to MIDI information, there are also momentary switches next to the valves as well as four MIDI controllers made by pressure sensing pads and potentiometers. It has a computer interface that enables the player to launch and modify sequences, record samples and handle them in real time and it also controls lighting and video or slide projection.
