# effect list
|
||
|
||
most of the effect numbers are 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 current note's pitch to the specified note. `x` is the slide speed.
|
||
- A note _must_ be present for this effect to work.
|
||
- `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, notes instantly change the pitch of the currrently 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.
|
||
- this can be used to shorten the current order.
|
||
- `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 sample bank.**
|
||
- Does not apply on Amiga.
|
||
- `EExx`: **Send external command.**
|
||
- This effect is currently incomplete.
|
||
- `F5xx`: **Disable macro.** see macro table at the end of this document for possible values.
|
||
- `F6xx`: **Enable macro.**
|
||
|
||
additionally, [each chip has its own effects](../7-systems/README.md).
