" I also aimed to make something novel that had never been done before. But to balance out the unusual nature of its design, I wanted to also to create something that was very musical.After much consideration of different technical design aspects and contemplating various musical ideas, I was able to arrive at a project that would fulfill all of my musical and engineering goals.An intelligent MIDI sequencer was designed with hamster control. The MIDI sequencer intelligently produced melodies by manipulating the musical elements of rhythm and note-choice. Guided by inputs based on hamster movements, Markov chains were used to perform such beat and note computations."
