  (Currently, not fully detailed. You can find more details at any
  MOD or S3M effects documentation (like ST3.DOC, MODEDIT3.DOC etc.))

 | Axy | [A]rpeggio [x,y= Halftones added to 2nd and 3th notes]
 | Bxx | set [B]PM to xx. range is 0Ah-FFh.
 | Cxx | [C]ut pattern, start next pattern at interval xx (decimal)
 | Dxy | portamento [D]own (Fine Porta if x=F, ExtraFine if x=E)
 | E   |
 | Fxy | [F]ine vibrato:   X = speed, Y = depth
 | G   |
 | H   |
 | I   |
 | Jxx | position [J]ump [xx = entry at sequence table]
 | K   |
 | L0x | vo[L]ume slide down by X
 | Lx0 | vo[L]ume slide up by X
 | LFx | [F]ine vo[L]ume slide down by X (if x=0 then normal slide UP by F)
 | LxF | [F]ine vo[L]ume slide up by X (if x=0 then normal slide DOWN by F)
 |     | LFF - Fine volume slide up by F
 |     |
 | M   | [M]iscellaneous
 |     |
 |     |  M3x = Glissando control; 0=Off, 1=On, 2=On+Retrigger
 |     |  M4x = vibrato wave (0=Sine, 1=Ramp Down, 2=Square)*
 |     |  M5x = finetune note
 |     |  M6x = pattern loop  (if x=0 then mark. elsewhere, loop x times)
 |     |  M7x = tremolo wave (0=Sine, 1=Ramp Down, 2=Square)*
 |     |  MCx = note Cut (x=time to wait until note cut)
 |     |  MDx = note Delay (x=time to wait until sample start)
 |     |  MEx = pattern delay (x=intervals to stay still)
 |     |
 |     | * Note: Add 4 to waveform value if you don't want it to
 |     |         be resetted upon every new note.
 |     |
 | Nxx | [N]ote portamento (also known as SLIDE TO NOTE, PORTA TO NOTE,
 |     |                                           and TONE PORTAMENTO)

 | Pxx | Channel [P]an control (Decimal) 0=Left>32=Mid>64=Right/66=Surround
 |     |                                70=Reset ALL channels pan settings
 | Rxy | [R]etrig note at Y
 | Sxx | set [S]peed to xx. Range is 0-50 hex. If xx=0 ignore effect.
 | Txy | [T]remolo:   X = speed, Y = depth
 | Uxy | portamento [U]p  (Fine Porta if x=F, ExtraFine if x=E)
 | Vxy | [V]ibrato:   X = speed, Y = depth
 | W   |
 | Xxy | Note port & volume slide (if either nibble is F, effect discarded)
 | Yxy | Vibrato & volume slide (if either nibble is F, effect discarded)

 - All references are Hexadecimal, unless otherwise noted.
 - Note that the effects VOLUME SLIDE, VIBRATO+VOLSLIDE, NOTEPORT+VOLSLIDE,
   PORTA UP, PORTA DOWN and ARPEGGIO support the S3M's parameter 0 feature.
   (if the parameter given is 0, the effect uses the last parameter used by
   any previous effect in the same track. i.e., you can specify D01 and then
   a column of D00, for easier tracking)
 - The letter representing an effect is usually the first letter of
   the effect, so it should not be too difficult remembering them.
 - Full description of the effects and their purposes will be included
   in later versions.
