Effect number	Description
0xy				Arpeggio, x = second note, y = third note
1xx				Pitch slide up, xx = speed (00 to disable)
2xx				Pitch slide down, xx = speed (00 to disable)
3xx				Automatic portamento, slides to new notes xx = speed (00 to disable)
4xy				Vibrato effect, x = speed (0 to disable), y = depth
7xy				Tremolo effect, x = speed (0 to disable), y = depth
Axy				Volume slide, A0x = slide down, Ax0 = slide up
Bxx				Jump to pattern xx
Cxx				Halt, stopping the song (xx doesn't do anything)
Dxx				Skip to next frame and start at row xx
Exx				Volume setting. Obsolete, use the volume column instead
Fxx				Speed/tempo, sets the speed when xx is between 00 - 1F, and tempo when xx is between 20 - FF
Gxx				Note delay, delay before the current row is triggered, xx = frames to wait
Hxy				Hardware sweep up, triggers a hardware sweep up (only available for square) x = period (0 - 7), y = shift (1 - 7)
Ixy				Hardware sweep down, triggers a hardware sweep down (only avaliable for square), x = period (0 - 7), y = shift (1 - 7)
Hxx				FDS modulation depth
Ixx/Jxx			FDS modulation speed (high part & low part)
Pxx				Fine pitch, xx = offset (80 is default)
Qxy				Note slide up, x = speed, y = number of semitones
Rxy				Note slide down, x = speed, y = number of semitones
Sxx				Mute delay, xx = frames before mute
Vxx				Square duty/noise mode/N163 wave, xx = 00 - 03 for square, 00 - 01 for noise and 00 - 0F for N163.
Wxx				DPCM sample speed override, xx = sample playback speed
Xxx				DPCM sample retrigger, xx = delay in frames
Yxx				DPCM sample offset, each step adds 64 bytes
Zxx				DPCM delta counter, changes the delta counter directly, affects volume of noise and triangle. xx is between 00 - 7F
