soprano saxophone or clarinet, except that its keys are activated by touch rather than being depressed (i.e. the player's fingers don't rest on the keys). Nyle Steiner’s EWI fingering was novel because it does not operate as an acoustic instrument. Instead of closing or opening a hole, each EWI key acts as a pitch modifier that can change note values by plus or minus a half step or whole step. As a result, fingerings that are similar to that of a Boehm instrument, but many other alternate fingers are possible on EWI that are not possible on acoustic instruments. This gave Steiner’s invention flexibility yet remains familiar to woodwind players. Later generation EWIs can be switched to flute, oboe, and saxophone fingering modes. The EWI 5000 and EWI USB also have an electronic valve instrument (EVI) fingering mode that allows brass players to play the EWI. Like a straight soprano saxophone or clarinet, the EWI is straight with a slight inward bend a few inches below the mouthpiece, and it is held in front of the body with a neck strap. The EWI has a silicone mouthpiece with sensors for air pressure (sending MIDI Breath Control by default) and bite pressure (which sends vibrato, more specifically a quick pitch up-down "blip" by default, but can also be routed to modulation or other CC controls of the player's preference). Because the EWI keys do not move (instead, they sense when fingers are touching them by body capacitance). Owing to the touch capacitative switches and breath and bite sensors the instrument is highly responsive, however, this sensitive nature of the touch capacitative switches does not immediately appeal to all players, some of which may prefer electronic wind instruments with mechanical buttons on which they can rest their fingers, more similar to a saxophone, though a short period of adjustment will allow wind players to easily adapt. It also requires substantially less breath control than an acoustic instrument; breath sensitivity is one of the parameters that can be adjusted to the player's preference. Unlike acoustic wind instruments, the fingering is identical in every octave. The current octave is determined by putting your left thumb between any two of the four to eight rollers (*depending on model), and also by rolling the thumb to the ends of the EWI USB roller track to achieve the fifth octave from just the four-octave rollers on that
