Description

Woolren is a phaser built for sound design. It has a deep set of modulators and a step sequencer, and it keeps the notches in your sound moving all the time.

Up to five phaser sections run in series, and each of the five phaser controls has its own LFO, so the notches, their width, the feedback, their spacing and the wet mix can all move at different rates. It can do slow, sweeping phasing or fast pulses that sound like tremolo. We also gave it an 8-step sequencer that follows your host tempo, for tight rhythmic filtering.

Woolren in the Handbook

Signal path

The step sequencer modulates the phaser matrix. The phased sound then goes through the reverb to the master section, where BLEND mixes it with your dry signal.

  1. Step sequencer

    TARGET
    Sends the sequencer to FILTER, DIST (distance) or BLEND, or turns it OFF. Each step scales the target's setting, from nothing at the bottom of a bar to the full fader value at the top.
    RATE
    Sets how fast the sequencer moves: 1/2, 1, 1.5 or 2 steps per quarter note at your host tempo.
    CLOCK
    On SELF the sequencer runs on its own at host tempo. On SYNC it moves only while the host transport is running, and it starts the pattern over each time you press play.
    STEPS
    You draw the eight step values by clicking or dragging across the bars. A playhead shows the current step while a TARGET is on.

  2. Phaser matrix

    FILTER
    Sets the center frequency of the first notch, from 20 Hz to 2 kHz. The other notches are spaced out from this one.
    WIDTH
    Sets the bandwidth of each notch. Higher values give narrower notches. The middle of the range gives the strongest phasing, and the extremes are good for special effects.
    FEEDBACK
    Feeds the output back into the phaser, positive above the center and negative below it. More feedback brings out more prominent notches.
    DISTANCE
    Sets how far apart the additional notches sit across the spectrum. It needs STAGES at 2 or more to do anything.
    BLEND
    Sets the phaser's own wet mix. Unlike the master BLEND, its LFO and the sequencer can move it.
    SPEED
    The SPEED knob under each fader (FILTER SPEED, WIDTH SPEED, FEEDBK SPEED, DIST SPEED, BLEND SPEED) sets the rate of that fader's LFO, from 0.001 to 4 Hz.
    AMT
    The AMT knob under each fader sets how far its LFO pulls the fader's value down. At full amount, FILTER sweeps all the way to zero. On BLEND it pulses between the dry and phased sound like a tremolo.
    SHAPE
    The small knob under each column picks the waveform for that LFO: triangle, saw, square or random (TRI, SAW, SQR, RND).
    STAGES
    Sets how many phaser sections are chained, from 1 to 5. More stages give more notches and a deeper, denser sweep.

  3. Space

    SPACE
    Sends the phased signal to a long reverb and mixes it in with the phaser.
    DAMP
    Sets the reverb's damping. Low values make the reverb dark and muffled, and high values keep it bright.

  4. Master

    BLEND
    Sets the mix between your dry sound and everything Woolren does. It starts fully wet, which is how the original plugin sounds.
    GAIN
    Sets the output level, from silent up to double. The middle is unity.

Try thisSet TARGET to FILTER and CLOCK to SYNC, then draw a falling pattern in the steps. The filter sweeps in time with your track and starts in the same place every time you press play.

Good to know

In Studies

Woolren is in Studies Effects, under Modifier.

Standalone

The standalone plugin, shown further down the page, sets the phaser sections with an ORDER menu labeled 4, 16, 32 and 64. It actually chained one to four sections, so in Studies the control is called STAGES and goes from 1 to 5. Studies also adds the master BLEND and GAIN, which the standalone plugin doesn't have.
