Pulveriser contains three main effect sections; Squash (compression), Dirt (distortion) and Filter (multi-mode filter with cutoff and resonance controls). In addition, Pulveriser features two modulation sections - an LFO with selectable waveforms and an Envelope Follower which can modulate the effect sections. The parameters in each section are as follows:
Note, however, that the Input Meter is different on the Pulveriser device. Instead of the standard multi-segment LED indicator found in other Reason effect devices, Pulveriser features a red lamp which reflects the intensity of the input signal.
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.
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 modulated signal is affected.
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.
The Lag control acts like a lowpass filter on the LFO signal, making the LFO signal smoother. This is especially noticeable 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.
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 relation to the sequencer playhead.
The Follower section features an envelope follower which analyzes the amplitude of the incoming signal and outputs a modulation (CV) signal that corresponds to the incoming audio level. The modulation signal can then control the Frequency parameter in the Filter section and/or the LFO Rate parameter in the Tremor section. The Follower section features the following parameters:
Click/hold the Trig button to manually trig/gate the envelope follower. Clicking/holding the Trig button will make the envelope follower output a modulation signal according to the settings of the Attack and Release parameters described below. If you hold the Trig button for a longer period than the Attack time, the Follower will output maximum CV signal level. When you then release the Trig button, the CV signal level will drop according to the Release time and continue to follow the audio input signal level instead.
This defines at which input signal level the envelope follower should trig. Set to a low value, the envelope follower will react as soon as there is any audio signal present on the Pulveriser inputs. Set to a high value, the envelope follower will react only on loud input signals, or from a manual Trig signal.
With the Blend knob you control the mix between the dry and wet signal. With the knob set somewhere in between the Dry and Wet position you will have parallel processing. This can be useful if you, for example, want to process a drum loop with compression (Squash) and distortion (Dirt) and mix the processed signal with the dry before sending it to the outputs.
