Getting Loopy: Performance Loopers For Linux Musicians
A loop in music is a section of the music that repeats itself continuously until receiving a signal to either stop or move on to the next section. A loop can be assigned to a single instrument or to a group of instruments.
Modern music-makers use loops in another context. Performance loopers are machines that record an audio signal and capture it to a buffer for use as a repeating loop over which a performer improvises a new musical line or even another loop. A performance looper records multiple loops, thus giving the user an opportunity to compose additively in realtime. All performance loopers share some basic characteristics such as recording, file loading, and various transport mechanisms.
