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 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), V (5B), W (5B).

The following effects have extra meanings in 0CC-FamiTracker:

- 0xy: The x and y parameters can be used in scheme arpeggio sequences. (This is how everything started)
- Fxx: Cancels the current groove.
- I0x (FDS): Disables automatic FM.
- Jxx (FDS): Ineffective if automatic FM is active.
- Sxx: On the triangle channel, disables the length counter and the linear counter.


Global Effects



Oxx: Groove setting.
xx = Groove index
Valid range = 00 - 1F

Note: The tracker ignores indices corresponding to blank grooves; it is undefined behaviour 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. 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 behaviour to use a wave position that conflicts with the channel registers. The tracker automatically ignores invalid parameters.
