| Cell | A note, an instrument, and an effect. This is a single row in a pattern. |
| Channel | One of the Game Boy’s 4 voices for producing sound. There are 2 pulse channels, one wave channel, and one noise channel. |
| Duty | The parameter that determines the waveform of a pulse channel. A pulse channel has two states (on or off), and the duty cycle specifies what percentage of the time it’s on. A pulse channel with 50% duty would emit a square wave. |
| Effect | Consists of an effect code and effect parameter. Used for a variety of reasons, including changing the way a specific note sounds, changing global settings such as master volume, affecting song tempo, or calling your own custom code. |
| Effect code | A hexadecimal digit which specifies which effect to use. |
| Effect parameter | Two hexadecimal digits which tweak the effect’s behavior. |
| Instrument | A bunch of parameters which change the way a channel produces sound. Each cell must include an instrument number. |
| Octave offset | When entering note values into the tracker grid, the value of the note is increased by , to allow for more natural entry of higher notes. |
| Order | A row of four pattern indices. An order is how you arrange patterns into a structured song. |
| Order table | A list of orders, representing the structure of the song. |
| Pattern | A list of 64 cells, used to represent 2 measures of music. This is the basic building block of your song. |
| Render | Exporting a song as a .wav or .mp3 file, so anybody can listen to them without hUGETracker or an emulator installed. |
| Routine | A custom effect written in Game Boy assembly. An advanced featuer that would typically be used when integrating hUGETracker into a homebrew game, or perhaps for making custom effects. |
| Song | The whole track, which includes patterns, orders, instruments, waves, and routines. |
| Sweep | A change of pitch over time. The Game Boy sound hardware provides the ability for the first pulse channel to perform a sweep as specified by some instrument parameters. |
| Tick | Every time the sound driver update function is called, it advances the song by one tick. This is usually done at around 60 Hz. |
| Tempo | The tempo of a song specifies how many ticks have to elapse before switching to the next row. The greater it is, the slower the song is. |
| Wave | A waveform which changes the timbre of the wave channel when selected. You can draw these in the wave tab. They must be associated to an instrument in the instruments tab. |
