 Furnace uses hexadecimal (abbreviated as "hex") numbers frequently. see [this guide](hex.md) for a crash course.

+Furnace uses a music tracker interface. think of a table with music notes written on it. then that table scrolls up and plays the notes.
 
 due to its nature of being feature-packed, it may be technical and somewhat difficult to get around. therefore we added a basic mode, which hides several advanced features.

-# concepts and terms
-
-- A **module** is a file for a tracker that contains at least one **song**.
-- Each Furnace module involves at least one **[chip](../7-systems/README.md)**, an emulation of a specific audio processor.
-
-## tracking
-
-The **[pattern view](../3-pattern/README.md)** is like a spreadsheet that displays the following:
-- Each labeled column represents a **channel** of sound provided by the chips in use.
-- Each **note** starts a sound playing. Within a channel, only one note can play at a time.
-- Each note is assigned an **[instrument](../4-instrument/README.md)** which describes what it will sound like.
-- An **effect** is a command that changes some aspect of playback. It can alter note pitch, volume, timing, and more.
-- An instrument **macro** is an automated sequence of effects that applies to every note of that instrument.
-
-## structure
-
-The **order list** is a smaller spreadsheet showing the overall song structure.
-- A song is made up of a list of **orders**.
-- An **order** is a set of numbered **patterns** used for each channel.
-- Each channel has its own unique list of patterns.
-- Each pattern contains note and effect data for that channel only.
-- Patterns may be used multiple times in the order list. Changing a pattern's data in one order will affect the same pattern used in other orders.
-
-## time
-
-- Each pattern is made of the same number of **rows** as seen in the tracker view.
-- During playback, Each row lasts a number of **ticks** determined by its **speed** value.
-- A tick is the smallest measure of time to which all note, effect, and macro times are quantized.
-
-## sound
-
-Different chips have different capabilities. Even within the same chip, each channel may have its own ways of making sound.
-- Some channels use one or more waveform **generators** (sine, square, noise...) to build up a sound.
-- Of special note are **[FM (frequency modulation)](../4-instrument/fm.md)** channels, which use a number of generators called **operators** that can interact to make very complex sounds.
-- Some channels use **[samples](../6-sample/README.md)** – recordings of sounds, often with defined loop points to allow a note to sustain.
-- Some channels use **[wavetables](../5-wave/README.md)**, which are like very short samples of fixed length that automatically loop.

 - Set the first virtual tempo number (numerator) to 200.
 - Set the second virtual tempo number (denominator) to 150.
