# 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`. - `00xy`: arpeggio. after using this effect the channel will rapidly switch between `note`, `note+x` and `note+y`. - `01xx`: slide up. - `02xx`: slide down. - `03xx`: note portamento. - a note must be present for this effect to work. - `04xy`: vibrato. `x` is the speed, while `y` is the depth. - maximum vibrato depth is ±1 semitone. - `08xy`: set panning. `x` is the left channel and `y` is the right one. - not all systems support this effect. - `09xx`: set speed 1. - `0Axy`: volume slide. - if `x` is 0 then this is a slide down. - if `y` is 0 then this is a slide up. - `0Bxx`: jump to pattern. - `0Cxx`: retrigger note every `xx` ticks. - this effect is not continuous. - `0Dxx`: jump to next pattern. - `0Fxx`: set speed 2. - `Cxxx`: change song Hz. - `xxx` may be from `000` to `3ff`. - `E0xx`: set arpeggio tick. - this sets the number of ticks between arpeggio values. - `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. - `E3xx`: set vibrato direction. `xx` may be one of the following: - `00`: up and down. - `01`: up only. - `02`: down only. - `E4xx`: set vibrato range in 1/16th of a semitone. - `E5xx`: set pitch. `80` is 0 cents. - range is ±1 semitone. - `EAxx`: toggle legato. - `EBxx`: set sample bank. - does not apply on Amiga. - `ECxx`: note off after `xx` ticks. - `EDxx`: delay note by `xx` ticks. - `EExx`: send external command. - currently not used, but this eventually will allow you to do special things after I add VGM export. - `EFxx`: add or subtract global pitch. - this effect is rather weird. use with caution. - `80` is center. additionally each system has its own effects. more details in another section of the manual.
