Music trackers (usually referred to simply as trackers) are a class of music sequencer software used to create and edit module files; they allow the user to arrange notes (pitch-shifted sound samples from the module) stepwise on a timeline across several monophonic channels.
A tracker's musical interface is traditionally numeric: both notes and parameter changes, effects and other commands are entered with the keyboard into a grid of fixed time slots as codes consisting of letters, numbers and hexadecimal digits. Separate patterns have independent timelines; a complete song consists of a master list of repeated and concatenated patterns.
Recent trackers have departed from module file limitations and advantages, adding other options both to the sound synthesis (hosting generic synthesizers and effects or MIDI output) and to the sequencing (MIDI input and recording), effectively becoming general purpose sequencers with a different user interface.
Famous quotes containing the word music:
“Nothing separates the generations more than music. By the time a child is eight or nine, he has developed a passion for his own music that is even stronger than his passions for procrastination and weird clothes.”
—Bill Cosby (b. 1937)
