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
