Sampler (musical instrument) Sampler (musical instrument) A sampler is an electronic or digital musical instrument similar in some respects to a synthesizer, but instead of generating new sounds with voltage-controlled oscillators, it uses sound recordings (or "samples") of real instrument sounds (e.g., a piano, violin or trumpet), excerpts from recorded songs (e.g., a five-second bass guitar riff from a funk song) or other sounds (e.g., sirens and ocean waves). The samples are loaded or recorded by the user or by a manufacturer. These sounds are then played back by means of the sampler program itself, a MIDI keyboard, sequencer or another triggering device
EWI (musical instrument) the EWI keys do not move (instead, they sense when fingers are touching them by body capacitance, much like an elevator button works), the instrument is very agile. 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 eight rollers. Touching a plate next to the rollers sends portamento by default. There are also pitchbend up and down
