The pattern effects in
0CC-FamiTracker expand upon those found in
FamiTracker.
This article is written based on version 0.3.14.5.
Existing Effects
The following effects are directly carried over from the latest stable release of vanilla
FamiTracker: 0, 1, 2, 3, 4, 7, A, B, C, D, F, G, H (2A03 / FDS), I (2A03 / FDS), J (FDS), P, Q, R, S, V (2A03 / MMC5 / VRC6 / VRC7 / N163), W (DPCM), X, Y, Z (DPCM).
The following effects have been ported from vanilla 0.5.0 beta: H (VRC7 / 5B), I (VRC7 / 5B), J (5B), V (5B), W (5B).
The following effects have additional usages in 0CC-FamiTracker:
0xy: The
x and
y parameters can be used in scheme arpeggio sequences.
Fxx: Cancels the current groove.
Hxx (VRC7): The address port is local to each channel, even in exported NSFs. Multiple writes could occur on the same tick.
Hxy (5B):
y can be zero; this effect does not control the envelope output flag.
I0x (FDS): Disables automatic FM.
Jxx (FDS): Ineffective if automatic FM is active.
Sxx: Also controls also the length counter and the linear counter on the triangle channel.
Vxx (5B): The usual parameters disable the envelope output.
Wxx (5B): Behaves like a global
Vxx effect but for noise pitch.
Global Effects
Oxx: Groove setting.
xx = Groove index
Valid range = 00 - 1F
Note: The tracker ignores indexes corresponding to blank grooves; it is
undefined behavior to use blank grooves in exported NSFs.
General Effects
Lxx: Delayed note release.
xx = Delay amount in ticks
Note:
L00 is equivalent to the usual note release (
===).
Mxy: Delayed channel volume. Restores existing channel volume on next note.
x = Delay amount in ticks
y = New channel volume
Valid range for
x and
y = 1 - F
Txy: Delayed transpose.
If
x = 0 - 7: Delay
x ticks, transpose upwards
If
x = 8 - F: Delay (
x - 8) ticks, transpose downwards
y = Semitones to transpose
Valid range for
y = 0 - F
Note: Affects the echo buffer.
2A03 / MMC5 Effects
Exx: Length counter setting; enables length counter.
xx: Length counter index: (default 01)

Note: Length counter is retriggered on new notes or when updating the high period register. The speed is twice as fast on the triangle channel.
Applies to: 2A03 Pulse, 2A03 Triangle, 2A03 Noise, MMC5 Pulse
EEx: Configure hardware envelope.
If
x = 0: Disable hardware envelopes (default)
If
x = 1: Enable hardware decay, looping
If
x = 2: Enable length counter
If
x = 3: Enable hardware decay, once
Note: When hardware decay is enabled, the channel volume will control the decay rate; 0 is the fastest.
Applies to: 2A03 Pulse, 2A03 Noise, MMC5 Pulse
EEx: Configure hardware envelope.
If
x = 0: Disable hardware envelopes (default)
If
x = 1 - 3: Enable length counter and linear counter
Applies to: 2A03 Triangle
Sxx: Triangle linear counter setting.
If
xx = 80 - FF: Cut notes after (
xx - 80) ÷ 240 seconds for all new notes
Applies to: 2A03 Triangle
FDS Effects
Exx: FDS hardware volume envelope setting.
If
xx = 00 - 3F: Attack envelope, 00 is the fastest
If
xx = 40 - 7F: Decay envelope, 40 is the fastest
If
xx = E0: Disable hardware volume envelope
Hxx: Automatic FM multiplier setting.
xx - 80 = Frequency multiplier
Valid range for
xx = 80 - FF
Ixy: Automatic FM; binds modulation rate to output frequency.
x = Frequency multiplier
y + 1 = Frequency divider
Valid range for
x = 1 - F
Valid range for
y = 0 - F
Zxx: Automatic FM rate bias.
If
xx < 80: Decrease FM rate after multiplication
If
xx = 80: Zero bias
If
xx > 80: Increase FM rate after multiplication
N163 Effects
Zxx: Wave buffer position setting.
If
xx = 00 - 7E: Override channel's wave position to
xx × 2
If
xx = 7F: Return control to N163 instruments
Note: It is
undefined behavior to use a wave position that conflicts with the channel registers. The tracker automatically ignores invalid parameters.
5B Effects
Vxx: Output setting.
If
xx = 00: Disable everything
xx + 1: Enable square tone output
xx + 2: Enable noise output
xx + 4: Enable envelope output
Note: This effect is now the only pattern effect that may toggle the envelope output.
