 This window allows one to create **subsongs** – multiple individual songs within a single file. Each song has its own order list and patterns, but all songs within a file share the same chips, samples, and so forth.

 There are multiple ways to set the tempo of a song.
 
-**Tick Rate** sets the frequency of ticks per second, the rate at which notes and effects are processed.

 - Clicking the "Speed" button changes to more complex modes covered in the [grooves] page.

+**Virtual Tempo**: Simulates any arbitrary tempo without altering the tick rate. It does this by adding or skipping ticks to approximate the tempo. The two numbers represent a ratio applied to the actual tick rate. Example:

 - Set the first virtual tempo number (numerator) to 200.
 - Set the second virtual tempo number (denominator) to 150.
 - The track will play at 200 BPM.
 - The ratio doesn't have to match BPM numbers. Set the numerator to 4 and the denominator to 5, and the virtual BPM becomes 150 × 4/5 = 120.
 
-**Divider** changes the effective tick rate. A tick rate of 60Hz and a divisor of 6 will result in ticks lasting a tenth of a second each!

-**Pattern Length** is the length of each pattern in rows. This affects all patterns in the song, and every pattern must be the same length. (Individual patterns can be cut short by `0Bxx`, `0Dxx`, and `FFxx` commands.)

 FM synthesizers Furnace supports are four-operator, meaning it takes four oscillators to produce a single sound. Each operator is controlled by a dozen sliders:
 
-- [Attack Rate (AR)] - determines the rising time for the sound. The bigger the value, the faster the attack. (0-31 range)
-- [Decay Rate (DR)]- Determines the diminishing time for the sound. The higher the value, the shorter the decay. It's the initial amplitude decay rate. (0-31 range)
-- [Secondary Decay Rate (DR2)/Sustain Rate (SR)] - Determines the diminishing time for the sound. The higher the value, the shorter the decay. This is the long "tail" of the sound that continues as long as the key is depressed. (0-31 range)
-- [Release Rate (RR)] - Determines the rate at which the sound disappears after KEY-OFF. The higher the value, the shorter the release. (0-15 range)
-- [Sustain Level(SL)] - Determines the point at which the sound ceases to decay and changes to a sound having a constant level. The sustain level is expressed as a fraction of the maximum level. (0-15 range)
-- [Total Level (TL)] - Represents the envelope’s highest amplitude, with 0 being the largest and 127 (decimal) the smallest. A change of one unit is about 0.75 dB.
-- [Envelope Scale (KSR)] - A parameter that determines the degree to which the envelope execution speed increases according to the pitch. (0-3 range)
-- [Frequency Multiplier (MULT)] - Determines the operator frequency in relation to the pitch. (0-15 range)
-- [Fine Detune (DT)] - Shifts the pitch a little (0-7 range)
