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 up. adds x to volume.
• F9xx: Single tick volume down. subtracts x from volume.

• D3xx: Volume portamento. slides volume toward the new value instead of jumping immediately. x is the speed of the slide.
• D4xx: Volume portamento (fast). same as D3xx but 256× faster.

• 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.

• D3xx: Volume portamento. slides the volume to the one specified in the volume column. x is the slide speed.
• a volume must be present with this effect for it to work.
• D4xx: Volume portamento (fast). like D3xx but four times faster.

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 up.
• F2xx: Single tick pitch 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.
