# effect list
|
||
|
||
some of the effect numbers are taken from ProTracker / FastTracker 2.
|
||
|
||
however, effects are continuous (unless specified), which means you only need to type it once and then stop it with an effect value of `00` or no effect value at all.
|
||
|
||
## volume
|
||
|
||
- `0Axy`: **Volume slide.**
|
||
- if `x` is 0 then this slides volume down by `y` each tick.
|
||
- if `y` is 0 then this slides volume up by `x` each tick.
|
||
- `FAxy`: **Fast volume slide.** same as `0Axy` above but 4× faster.
|
||
- `F3xx`: **Fine volume slide up.** same as `0Ax0` but 64× slower.
|
||
- `F4xx`: **Fine volume slide down.** same as `0A0x` but 64× slower.
|
||
- `F8xx`: **Single tick volume slide up.** adds `x` to volume on first tick only.
|
||
- `F9xx`: **Single tick volume slide down.** subtracts `x` from volume on first tick only.
|
||
- ---
|
||
- `07xy`: **Tremolo.** changes volume to be "wavy" with a sine LFO. `x` is the speed. `y` is the depth.
|
||
- tremolo is downward only.
|
||
- maximum tremolo depth is -60 volume steps.
|
||
|
||
## pitch
|
||
|
||
- `E5xx`: **Set pitch.** `00` is -1 semitone, `80` is base pitch, `FF` is nearly +1 semitone.
|
||
- `01xx`: **Pitch slide up.**
|
||
- `02xx`: **Pitch slide down.**
|
||
- `F1xx`: **Single tick pitch slide up.**
|
||
- `F2xx`: **Single tick pitch slide down.**
|
||
- ---
|
||
- `03xx`: **Portamento.** slides the currently playing note's pitch toward the new note. `x` is the slide speed.
|
||
- a note _must_ be present with this effect for it to work.
|
||
- the effect stops automatically when it reaches the new note.
|
||
- `E1xy`: **Note slide up.** `x` is the speed, while `y` is how many semitones to slide up.
|
||
- `E2xy`: **Note slide down.** `x` is the speed, while `y` is how many semitones to slide down.
|
||
- ---
|
||
- `EAxx`: **Toggle legato.** while on, new notes instantly change the pitch of the currently playing sound instead of starting it over.
|
||
- `E6xy`: **Quick legato (compatibility).** transposes note by `y` semitones after `x` ticks.
|
||
- if `x` is between 0 and 7, it transposes up.
|
||
- if `x` is between 8 and F, it transposes down.
|
||
- `E8xy`: **Quick legato up**. transposes note up by `y` semitones after `x` ticks.
|
||
- `E9xy`: **Quick legato down**. transposes note down by `y` semitones after `x` ticks.
|
||
- `00xy`: **Arpeggio.** this effect produces a rapid cycle between the current note, the note plus `x` semitones and the note plus `y` semitones.
|
||
- `E0xx`: **Set arpeggio speed.** this sets the number of ticks between arpeggio values. default is 1.
|
||
- ---
|
||
- `04xy`: **Vibrato.** makes the pitch oscillate. `x` is the speed, while `y` is the depth.
|
||
- maximum vibrato depth is ±1 semitone.
|
||
- `E3xx`: **Set vibrato shape.** `xx` may be one of the following:
|
||
- `00`: sine (default)
|
||
- `01`: sine (upper portion only)
|
||
- `02`: sine (lower portion only)
|
||
- `03`: triangle
|
||
- `04`: ramp up
|
||
- `05`: ramp down
|
||
- `06`: square
|
||
- `07`: random
|
||
- `08`: square (up)
|
||
- `09`: square (down)
|
||
- `0a`: half sine (up)
|
||
- `0b`: half sine (down)
|
||
- `E4xx`: **Set vibrato range** in 1/16th of a semitone.
|
||
|
||
## panning
|
||
|
||
not all chips support these effects.
|
||
|
||
- `08xy`: **Set panning.** changes stereo volumes independently. `x` is the left channel and `y` is the right one.
|
||
- `88xy`: **Set rear panning.** changes rear channel volumes independently. `x` is the rear left channel and `y` is the rear right one.
|
||
- `81xx`: **Set volume of left channel** (from `00` to `FF`).
|
||
- `82xx`: **Set volume of right channel** (from `00` to `FF`).
|
||
- `89xx`: **Set volume of rear left channel** (from `00` to `FF`).
|
||
- `8Axx`: **Set volume of rear right channel** (from `00` to `FF`).
|
||
- ---
|
||
- `80xx`: **Set panning (linear).** this effect behaves more like other trackers:
|
||
- `00` is left.
|
||
- `80` is center.
|
||
- `FF` is right.
|
||
- ---
|
||
- `83xy`: **Panning slide.**
|
||
- if `y` is 0 then this pans to the left by `x` each tick.
|
||
- if `x` is 0 then this pans to the right by `y` each tick.
|
||
- be noted that panning macros override this effect.
|
||
- `84xy`: **Panbrello.** makes panning oscillate. `x` is the speed, while `y` is the depth.
|
||
- be noted that panning macros override this effect.
|
||
|
||
## time
|
||
|
||
- `09xx`: **Set speed/groove.** if no grooves are defined, this sets speed. if alternating speeds are active, this sets the first speed.
|
||
- `0Fxx`: **Set speed 2.** during alternating speeds or a groove, this sets the second speed.
|
||
- ---
|
||
- `Cxxx`: **Set tick rate.** changes tick rate to `xxx` Hz (ticks per second).
|
||
- `xxx` may be from `000` to `3FF`.
|
||
- `F0xx`: **Set BPM.** changes tick rate according to beats per minute. range is `01` to `FF`.
|
||
- ---
|
||
- `FDxx`: **Set virtual tempo numerator.** sets the virtual tempo's numerator to the effect value.
|
||
- `FExx`: **Set virtual tempo denominator.** sets the virtual tempo's denominator to the effect value.
|
||
- ---
|
||
- `0Bxx`: **Jump to order.** `x` is the order to play after the current row.
|
||
- this marks the end of a loop with order `x` as the loop start.
|
||
- `0Dxx`: **Jump to next pattern.** skips the current row and remainder of current order. `x` is the row at which to start playing the next pattern.
|
||
- this can be used to shorten the current order as though it had a different pattern length.
|
||
- `FFxx`: **Stop song.** stops playback and ends the song. `x` is ignored.
|
||
|
||
## note
|
||
|
||
- `0Cxx`: **Retrigger.** repeats current note every `xx` ticks.
|
||
- this effect is not continuous; it must be entered on every row.
|
||
- `ECxx`: **Note cut.** triggers note off after `xx` ticks. this triggers key off in FM/hardware envelope chips, or cuts note otherwise.
|
||
- `EDxx`: **Note delay.** delays note by `x` ticks.
|
||
- `FCxx`: **Note release.** releases current note after `xx` ticks. this releases macros and triggers key off in FM/hardware envelope chips.
|
||
- `E7xx`: **Macro release.** releases macros after `xx` ticks. this does not trigger key off.
|
||
|
||
## sample offset
|
||
|
||
these effects make the current playing sample on the channel jump to a specific position.
|
||
only some chips support this effect.
|
||
|
||
sample offset is a 24-bit (3 byte) number.
|
||
|
||
- `90xx`: **Set sample offset (first byte).**
|
||
- `91xx`: **Set sample offset (second byte).**
|
||
- `92xx`: **Set sample offset (third byte).**
|
||
|
||
you may use these effects simultaneously in a row.
|
||
|
||
if you do not set a byte, its last value will be used.
|
||
|
||
in previous versions of Furnace a `9xxx` effect existed which set the sample position to `$xxx00` (`xxx` was effectively multiplied by 256). this maps to `920x 91xx` in current Furnace.
|
||
|
||
## other
|
||
|
||
- `EBxx`: **Set LEGACY sample mode bank.** selects sample bank. used only for compatibility.
|
||
- does not apply on Amiga.
|
||
- `EExx`: **Send external command.**
|
||
- this effect is currently incomplete.
|
||
- `F5xx`: **Disable macro.**
|
||
- `F6xx`: **Enable macro.**
|
||
- `F7xx`: **Restart macro.**
|
||
- see macro table at the end of this document for possible values.
|
||
|
||
additionally, [each chip has its own effects](../7-systems/README.md).
