Early computer sound chips had only simple tone and noise generators with few channels, imposing limitations on both the complexity of the sounds they could produce and the number of notes that could be played at once. In their desire to create a more complex arrangement than what the medium apparently allowed, composers developed creative approaches when developing their own electronic sounds and scores, employing a diversity of both methods of sound synthesis, such as pulse width modulation and wavetable synthesis, and compositional techniques, such as a liberal use of arpeggiation. The resultant chiptunes sometimes seem harsh or squeaky to the unaccustomed listener.
The June 2008 issue of Paste Magazine has an article on chiptune artist Jeremiah "Nullsleep" Johnson, and the included sampler CD features chiptune song "Local Hero" by Crazy Q.
