A sampler is an electronic musical instrument or device used to record, manipulate, and playback audio samples. These samples can be recordings of real instruments, vocals, or any other sound source. Samplers typically allow users to trigger and manipulate these samples in various ways, such as adjusting pitch, tempo, and volume, as well as applying effects like reverb or distortion. They are widely used in music production, allowing musicians, producers, and DJs to create original compositions, remix existing tracks, and add depth and texture to their music. Samplers come in various forms, ranging from dedicated hardware units to software plugins that run on computers or digital audio workstations (DAWs), offering a versatile and powerful tool for sonic experimentation and creativity.
