Most electric wind instruments /electronic-wind-instrument/electric-saxophone-ewi.htmlhave built-in sound effects such as vibrato, glissando, and pitch bend. Take some common electric wind instruments as examples:
- **Vibrato effect**:
- **Existence**: Many electric wind instruments have vibrato functions. For example, the Huamei AC966 has three vibrato modes built into the mouthpiece, including fully automatic vibrato, semi-automatic vibrato, and technical vibrato. When fully automatic vibrato is turned on, every note played will have its own vibrato; semi-automatic vibrato is when vibrato is needed, just bite the mouthpiece and keep it still to produce even vibrato; technical vibrato requires the teeth to bite down and release the mouthpiece to produce free vibrato, which is suitable for professional players to produce vibrato at different rates according to the different emotions of the song.
- **Natural degree and adjustability**: Some high-end electric wind instruments perform better in the natural degree of vibrato, and can simulate the vibrato effect of traditional wind instruments more realistically. And in terms of adjustment, there are usually relevant setting options or sensors, so that the performer can adjust the frequency, amplitude and other parameters of the vibrato according to their needs, which is also convenient to adjust.
- **Glide effect**:
- **Existence**: This is also one of the common built-in sound effects of electric blowpipes. During the performance, the glissando effect can be achieved by pressing the down glissando key or using specific fingering operations. For example, the button layout of Yamaha's electric blowpipe products has been carefully designed to facilitate the performer to perform glissando and other technical operations.
- **Natural degree and adjustability**: Generally speaking, the glissando effect of the electric blowpipe can meet the needs of most players in normal use and present a more natural transition. In terms of adjustment, some electric blowpipes can adjust the speed of the glissando, the pitch difference between the starting sound and the ending sound, etc. by setting the parameters in the menu, which has a certain degree of adjustability, but the adjustment accuracy of different brands and models may vary.
- **Pitch bend effect**:
- **Existence**: Electric blowpipes usually have a dedicated pitch bend key to achieve the pitch bend effect. For example, Akai's EWI SOLO electric blowpipe has simplified the up and down pitch bend keys, retaining only one down pitch bend key, and adding a finger rest for easy holding, which is convenient for the performer to operate the pitch bend.
- **Naturality and Adjustability**: The naturalness of the pitch bend effect also depends on the quality and design of the electric blowpipe. Some high-quality electric blowpipes can achieve a more natural pitch bend effect through sensitive sensors and precise algorithms, allowing the performer to flexibly control the change of pitch during the performance. In terms of adjustment, the range, speed and other parameters of the pitch bend can usually be set to meet different performance needs.
However, different brands and models of electric blowpipes will have differences in the implementation, naturalness and adjustability of these sound effects. Some low-end electric blowpipes may perform relatively poorly in the naturalness of the sound effects and the convenience of adjustment. If you have high requirements for these sound effects, it is recommended to choose electric blowpipe products with higher quality and better reputation.
