LFO (LOW FREQUENCY OSCILLATOR)
Essentially, an LFO allows you to move a parameter’s value up and down automatically. LFOs generate
repeating waveforms in the sub-audio range, which are useful for creating repeating effects like pitch
vibrato, lter sweeps or pulse width modulation. The Mother-32’s LFO is also capable of audio-rate
modulation, which can be used to add harmonic complexity to any selected destination.
LFO RATE
This control is used to determine the LFO’s modulation frequency, which ranges
from about 0.1Hz to approximately 350Hz. The LFO can reach up to 600Hz if an
external control voltage is applied to the LFO RATE patch-point.
LFO WAVE
The LFO has two available modulation shapes: Square and Triangle. The
selected LFO waveshape is automatically transmitted to the VCO MOD
SOURCE and VCF MOD SOURCE selector switches with no patching required.
TRIANGLE
Triangle waves are useful for creating smooth up and down changes in
pitch or pulse width. They are ideal for musical pitch vibrato and pulse
width modulation, but can also be used at audio rates for FM sounds.
SQUARE
Square waves are useful for crafting trills, multi-octave pitch jumps, mimicking the behavior of
a slap delay, or for simply adding an additional rhythmic element to a sequence or held note.
NOTE: The LFO Triangle and Square waveforms both have dedicated output jacks on the
patchbay: LFO TRI and LFO SQ.
TIP: By patching the KB CV output to the LFO RATE CV input, you are able to increase and
decrease the LFO Rate based on the pitch of each note played.
MIX (VOLTAGE CONTROLLED)
MIX
Your Mother-32 has a voltage controlled mixer in the audio path. It is internally
routed and AC coupled to receive sound sources; mix them together and pass
them to the Filter. The MIX control blends between the selected VCO waveform
(counterclockwise) and an onboard White Noise generator, or signal plugged
into the EXT. AUDIO input jack (clockwise). The blend can be set manually, or
can be dynamically modulated via the MIX CV input on the patchbay.
NOTE: If a patch cable is plugged into the EXT. AUDIO input on the patchbay,
it will override the normalization of White Noise to the clockwise position of this mixer. The External
Audio input is designed to receive a +/-5V signal. A line level signal will be very weak in volume when
compared with the internal VCO.
