Designed to augment the output of a solo electric guitar or other instrument, DroneBar uses pitch tracking to pull prominent tones into feedback-mimicking drones. As these tones rise and fall, the program gradually gathers information about the most prominent tones and uses it to generate passages when silence is detected from the guitar. When the bank of prominent tones is filled, the program begins adding to a Markov matrix, and its algorithmic composition becomes more structured. The program is messy, prioritizing aesthetics over algorithmic elegance. A host of parameters allow tuning of the software instrument, with substantially different sounds resulting from different thresholds and array sizes.
