'[t[code]0xy - Arpeggio, fast note shifting. x and y notes above the row-note. 

1xx - Portamento Up, slide up. xx = speed. 
100 - Portamento Up Off.

2xx - Portamento Down. slide down. xx = speed. 
200 - Portamento Down Off.

3xx - Glissando note.. xx = speed.
300 - Glissando note Off.

4xy - Vibrato. x = speed (0 = disable), y = depth. 

7xy - Tremolo. x = speed (0 = disable), y = depth. 

Bxx - Jump to frame xx. 

Cxx - Halt.xx doesn't do anything. 

Dxx - Skip to next frame and start at row xx. 

Exx - Set volume.xx = 0 - 15. 
Obsolete, use the volume column! 

Fxx - Set speed/tempo. 0 < xx < 20 sets the speed, 20 <  xx < FF sets the tempo. 

Gxx - Note delay. xx in frames. 

Hxy - Trigger hardware sweep up. x = period (0 - 7 ), y = shift (1 - 7). 
This feature is only avaliable for the square channels. 

Ixy - Trigger hardware sweep down. x = period (0 - 7), y = shift (1 - 7). 
This feature is only avaliable for the square channels. 

Pxx - Fine pitch setting. Default xx is 80, xx > 80 to increase pitch, and xx < 80 to decrease pitch. 

Vxx - Set Duty Cycling. Valid values, V00, V01, V02, V03.

Yxx - Start Sample Offset. with 64 bytes per step. (DPCM only)

Zxx - Set the DPCM's delta counter. Affects volume of triangle and noise. 0 < xx < 80
Note: using Zxx in big intervals (Z79 and then Z01 causes a 'clicking' sound. The nes hardware does this.)


Notes: 
E will not work if an instrument volume effect loop is used. 
1 will not work if an instrument frequency effect loop is used. (Pitch, Hi-pitch and Arpeggio)
