effect list

some of the effect numbers are taken from ProTracker / FastTracker 2.

however, effects are continuous, 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.
• 00xy: Arpeggio. after using this effect the channel will rapidly switch between semitone values of note, note + x and note + y.
• E0xx: Set arpeggio speed. this sets the number of ticks between arpeggio values. default is 1.

• 04xy: Vibrato. changes pitch to be "wavy" with a sine LFO. x is the speed, while y is the depth.
• maximum vibrato depth is ±1 semitone.
• E3xx: Set vibrato direction. xx may be one of the following:
• 00: up and down. default.
• 01: up only.
• 02: down only.
• 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.

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.

• 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. ends current note after xx ticks. for FM instruments, it's equivalent to a "key off".
• EDxx: Note delay. delays note by x ticks.

other

• 9xxx: Set sample position. jumps current sample to position xxx * 0x100.
• not all chips support this effect.
• 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.
• see macro table at the end of this document for possible values.

additionally, each chip has its own effects.

the interpretation of duty, wave and extra macros depends on chip/instrument type:
