PULVERISER548
The Tremor section
The Tremor section in Pulveriser is an LFO which can modulate the Filter Frequency parameter and/or the main out-
put Volume parameter. The Tremor section features the following parameters:
Rate
Controls the LFO rate. The Rate range in Pulveriser is very wide and can reach way up in the audio frequency range.
The rate can also be synced to the sequencer tempo by clicking the Sync button to the right (see “Sync” below). In
sync mode, the Rate knob controls the sync resolution.
As a special feature, the rate can also be modulated from the envelope follower in the Follower section, see “The Fol-
lower section”.
Waveform selector
Select one of nine LFO waveforms. Apart from standard waveforms (sine, triangle, square etc.) there are random,
non-linear and stepped waveforms. The shape of the waveforms are shown in the display and reflect how the modu-
lated signal is affected.
Sync
Click the Sync button to synchronize the LFO Rate to the main sequencer tempo. In Sync mode the LFO cycle is also
synced to the sequencer, which means that the LFO cycle chases the current sequencer position.
Control the sync resolution with the Rate knob, see “Rate” above.
Spread
The Spread button introduces a stereo effect by modulating the left and right audio channels with two LFO signals
phase shifted 180 degrees in relation to each other. This means that you are able to generate kind of a “roto-
speaker” effect to the processed signal.
Lag
The Lag control acts like a lowpass filter on the LFO signal, making the LFO signal smoother. This is especially no-
ticeable on waveforms with sharp edges or transients like the square, sawtooth and stepped waves. On the sinewave
you will barely notice any effect since it’s already “smooth” by nature.
Modulation Amount knobs
On either side of the Tremor section are two bipolar modulation amount knobs, with zero modulation at the 12 o’clock
position. Since the modulation parameters are bipolar it means that if the knob is in the “-” sector it will invert the LFO
wave shape. This is especially useful in LFO Sync mode where you can define the “direction” of the modulation in re-
lation to the sequencer playhead.
D Turn the left knob to control the modulation of the Frequency parameter of the Filter section.
D Turn the right knob to control the modulation amount of the wet signal of the Volume parameter.
This will introduce a tremolo effect to the Wet signal fed via the Volume control.
! Note that the Dry signal in the Blend section is never affected by the tremolo effect! This means that if the
Blend knob is set to fully Dry, there won’t be any tremolo effect of the volume.
