LOW FREQUENCY OSCILLATORS (LFO’s)
Monomachine SFX-6/60 USER’S MANUAL 35
WAVEFORM
The Waveform selection switch (“WAVE”) select waveform for the LFO from
the eleven shapes available. There are 5 basic shapes plus mirrored copies
of all but the Random (“RND”) shape. Select the appropriate waveform with
the Waveform switch. The waveform shapes and their start and end LFO
levels are carefully selected to give a wide range of shapes in combination
with the trig modes. See the figure above for all possible combinations.
• TRI = Triangular waveform
• ITRI = Inverse Triangular waveform
• SAW = Saw tooth waveform
• ISAW = Inverse Saw tooth waveform
• SAW = Saw tooth waveform
• ISAW = Inverse Saw tooth waveform
• EXP = Exponential Decay
• IEXP = Inverse Exponential Decay
• RMP = Linear Ramp
• IRMP = Inverse Linear Ramp
• RND = Random Levels
SPEED
The Multiplier ("MULT") and Speed ("SPD") parameters sets the LFO
speed relative to the master tempo. Speed is a linear controller that sets a
base speed that is multiplied with the Multiplier parameter. The use of both a
speed controller and a multiplier allows a very wide range of speeds, but still
provides a high degree of control. To get the finest resolution keep the Multi-
plier set as low as possible.
Increasing the Speed values gives shorter LFO cycle times. Each increase
of the Multiplier halves the LFO cycle time. For LFO speed synchronised to
straight beats, try setting Speed to 16, 32, 64 or 127. For example setting
the Multiplier to 2x and Speed to 64 gives a cycle time of sixteen 1/16 notes
(one full page).
INTERLACE
The Interlace (Parameter “INTL”) function is taken straight from the SidSta-
tion. Interlace is the process of alternating the LFO waveform with zero. The
speed of the zero-alternating cycles is controlled by the Interlace parameter.
The interlace is switched off when set to zero. Interlace can be particularly
interesting to use with trigged ramps with pitch as destination for creating
glittery rain-style effects.
DEPTH
The Depth (“DPTH”) is the amount of the LFO output level that is applied to
the target parameter. Setting Depth to 127 allows for modulating a parame-
ter to and from any extreme value. For example, if the target parameter is
set to 64 a Depth setting of 64 is sufficient for modulating the target value to
its minimum (0) and maximum (127).
