These are the effects commands available for the 6 chips supported thus far by DefleMask Tracker. The ones that begin with a 1 are always system-specific (also 2 for the SN76489 and SEGA PCM) so make sure you do not mix them up after switching systems!

Global Effects

This effect will enable the noise output of the 4th operator of the last FM
channel. 00 means disabled, standard behavior as a FM operator. From 0x01
to 0x20 (HEX) you will set the white noise frequency. This provides
independence from the main frequency of the other operators (to make noise
and kick at the same time at different pitches, for example)

12xx - Operator 1 total level setting.
13xx - Operator 2 total level setting.
14xx - Operator 3 total level setting.

y = Multiplier factor


17xx - Set LFO Speed.
This effect will set the LFO’s speed. It starts disabled (00), the max value is FF.


18xx - Set LFO Waveform.
This effect will change the LFO waveform, 0 SAW, 1 SQUARE, 2 TRIANGLE, 3
NOISE.


19xx - All operators attack rate setting.
1Axx - Operator 1 attack rate setting.
1Bxx - Operator 2 attack rate setting.

If xx = 00-1F: New AR value


ARCADE (SEGA PCM)




20xx - Set Sample Delta.
This effect will set the speed of sample playback, very useful to make tonal
samples. The formula is: delta*(31250/255)hz = sample hz
