Effect reference

This section describes the options you can use in patterns to apply effects to sounds or change music progression. It is also possible to define synchronization points between the music and the replay application once exported and integrated.

"Special" column

Effects for leftmost “special” column:

Option Description
Txx Set tempo
T00 is ignored
T01 is the fastest tempo
Bxx Break pattern
if xx=0, jump to the first step of the next pattern in the songlist after the current step
ignored if xx is different than 00
Exx Entry point
if xx=00 to 3F, indicates to export stage that a music entry point is requested at this location
ignored if other values are used
Sxx Signal to external application
if xx=00 to 7F, indicates to export stage that the sending of a signal (call or poke) is requested when the music reaches this location
ignored if other values are used

A/B/C channels

Effets for A, B and C channels:

Option Persistent Description
Axy O 3 note Arpeggio: +0 +x +y (semitone values)
Uxy N Slide pitch Up (portamento up)
xy: speed/step; 0x=repeat last value
Dxy N Slide pitch Down (portamento down)
xy: speed/step; 0x=repeat last value
I0x N Fade volume In
option ignored if upper nibble is different from 0
O0x N Fade volume Out
option ignored if upper nibble is different from 0
Vxy O Vibrato
x=speed (1 is the fastest; option ignored if 0y)
y=depth (x0 stops vibrato; option ignored if y > 7)
Xxx O Stop all FXs (arpeggio, arp seq, vibrato, pitch seq, SID offset)
xx parameter is ignored
Sxx O Use arpeggio Sequence (option ignored if xx > 63)
Pxx O Use Pitch sequence (option ignored if xx > 63)
Bxx O Change arpeggio speed (Axy or Sxx arpeggio)
Qxx O Change pitch sequence speed
Jxx O Change instrument speed
Zxx O Set SID offset (add offset to calculated note, unit is 1 HBL)
xx is a signed hexadecimal value (FF represents -1), default is 0.
This option is not related to a channel as there is only one SID at a time.

The second column indicates whether the effect continues implicitly without being repeated from row to row.
