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.

• 07xy: tremolo. x is the speed, while y is the depth.

  • maximum tremolo depth is -60 volume steps.

• 08xy: set panning. x is the left channel and y is the right one.

  • not all chips support this effect.

• 80xx: set panning (linear). this effect behaves more like other trackers:

  • 00 is left.
  • 80 is center.
  • FF is right.
  • not all chips support this effect.

• 81xx: set volume of left channel (from 00 to FF).

  • not all chips support this effect.

• 82xx: set volume of right channel (from 00 to FF).

  • not all chips 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.

• 9xxx: set sample position to xxx*0x100.

  • not all chips support this effect.

• 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.

  • this effect is currently incomplete.

• F0xx: change song Hz by BPM value.

• F1xx: single tick slide up.

• F2xx: single tick slide down.

• F3xx: fine volume slide up (64x slower than 0Axy).

• F4xx: fine volume slide down (64x slower than 0Axy).

• F5xx: disable macro.

  • see macro table at the end of this document for possible values.

• F6xx: enable macro.

• F8xx: single tick volume slide up.

• F9xx: single tick volume slide down.

• FAxy: fast volume slide (4x faster than 0Axy).

  • if x is 0 then this is a slide down.
  • if y is 0 then this is a slide up.

• FFxx: end of song/stop playback.

additionally each chip has its own effects. click here for more details.
