Modulate Sculpture LFOs
Two modulation targets can be assigned per LFO. An optional via modulation can also
be assigned.
The LFOs also feature a simple envelope generator, which is used to control the time it takes for
the LFO modulation to fade in or fade out. At its center position, which is accessed by clicking
the middle mark, the modulation intensity is static—in other words, no fade-in or fade-out
will occur.
Click the 1 or 2 buttons
to activate each source.
LFO target and source parameters
•
LFO Modulation On/O buttons (1 and 2): Turn each LFO on or o, independently.
•
Modulation Target pop-up menus: Choose the modulation targets.
•
Via Source pop-up menus: Choose (or disable) the via sources that control the modulation
scaling for each LFO.
•
Amt sliders: Move to set the modulation amount (when the incoming via signal is 0)— for
example, when the modulation wheel is at its minimum position.
In cases where the via source is set to o, only one amount slider is visible (the via amount
slider is hidden). In cases where any via source other than o is selected, there are two sliders.
•
Via (Amount) sliders: Move to set the via modulation amount (when the incoming via signal is
at its maximum)—for example, when the Modulation wheel is at the maximum position.
Set the LFO modulation fade time
m To fade in the modulation: Rotate the Envelope knob to a positive value.
The higher the value, the longer is the delay time.
m To fade out the modulation, rotate the Envelope knob to a negative value.
The farther to the left the knob is positioned, the shorter is the fade-out time.
Set up a delayed vibrato
LFO envelopes are most often used for delayed vibrato—many instrumentalists and singers
intonate longer notes this way.
1 Set the LFO Envelope knob toward the right (Delay) and choose pitch as the target.
2 Set a slight modulation intensity.
3 Select an LFO Rate of 5 Hz.
4 Choose the triangular wave as the LFO waveform.
Tip: Chaotic and fast modulations of pitch by an LFO source—with a delayed Sample&Hold
waveform, a high Rate, and short fade-out—are ideal for emulating the attack phase of
brass instruments.
