The PRP Voyager is a generative musical instrument with a complex mapping interface based on user made presets. Presets are prepared beforehand or made during improvisation. Pulse envelopes are generated using the Pseudo Random Pulse (PRP) algorithm. The envelopes can be utilized to mask a broad variety of carrier oscillator algorithms. PRP generates patterns with a pseudo random quality that serve as a distinct musical language. The PRP patterns can be recorded and looped to create repeating patterns while still retaining a certain sense of pseudo randomness within the groove of the loops. This paper discusses the implementation, and development of the algorithm and instrument.
