What’s it with Logic Pro’s stock plugins that make me think they’re WYSIWYG? I mean, last week I ‘discovered’ that the Distortion plugin actually has a very handy Level Compensation button. I clearly forget about these Extended Parameters all the time. So, for the sake of sanity, once and for all, here’s an overview of Logic Pro’s stock plugins that have Extended Parameters, in order of appearance in your plugin menu. All Extended Parameters’ descriptions are taken from the Logic Studio Effects Manual, for this overview I’ve included them in this article. Which one did you miss? No more excuses now.

Delay

Tape Delay

This slider determines the level of the distorted (tape saturation) signal.

Distortion

Bitcrusher

Sets the balance between dry (original) and wet (effect) signals. Parallel Bitcrushing at your fingertips.

Clip Distortion

Sets the amount of gain applied to the input and the output signal.

Distortion

This one I missed. With Level Compensation set to ‘On’, what you’ll hear is an increase in perceived loudness when you increase ‘Drive’.

Phase Distortion

For Stereo Instances: Reduce the delay time on the right channel when input signals that exceed the cutoff frequency are received.

Dynamics

Adaptive Limiter

• OptFit: Limiting follows a linear curve, which allows signal peaks above 0 dB.
• NoOver: Avoids distortion artifacts from the output hardware by ensuring that the signal does not exceed 0 dB.
• Lookahead field and slider: Adjusts how far ahead the Adaptive Limiter analyzes the file for peaks.

Compressor

• Output Distortion pop-up: Choose whether to apply clipping above 0 dB, and type of clipping.
• Activity pop‐up menu: Enables or disables the side chain filter.
• Mode pop-up menu: Choose the type of filter used for the side chain filter.
• Frequency slider: Sets the center frequency for the side‐chain filter.
• Q slider: Sets the width of the frequency band affected by the side‐chain filter.
• Gain slider: Sets the amount of gain applied to the filter band.
• Mix slider and field: balance between dry and wet signals.

EQ

Channel EQ

• Analyzer Mode buttons: Peak or RMS.
• Analyzer Decay slider: Adjust the decay rate of the Analyzer curve (peak decay in Peak mode or an averaged decay in RMS mode).
• Gain‐Q Couple Strength: Choose the amount of Gain‐Q coupling.
• The asymmetric settings feature a stronger coupling for negative gain values than for positive values, so the perceived bandwidth is more closely preserved when you cut, rather than boost, gain.

Linear Phase EQ

See ‘Channel EQ’.

Match EQ

Select the Fade Extremes checkbox smooth the filter curve at the high and low extremes of the frequency spectrum.

Modulation

Modulation Delay

• All Pass button: Introduces an additional allpass filter into the signal path.
• All Pass Left and All Pass Right: Determines the frequency at which the phase shift crosses 90° for each of the stereo channels.

Tremolo

Offset slider: Sets the amount that the modulation (cycle) is shifted to the left or right.

Pitch

Pitch Shifter 2

• Delay slider: Sets the amount of delay applied to the input signal.
• Crossfade slider: Sets the range used to analyze the input signal.
• Stereo Link radio buttons: Select Inv. to invert the stereo channel’s signals.

Vocal Transformer

• Glide slider: Determines the amount of time the vocal transformation takes.
• Grain Size slider: allows you to set the size of the grains of the granular algorithm. Try Auto first.
• Formants pop‐up menu: The “Keep Unvoiced Formants” option leaves sibilant sounds in a vocal performance untouched.
• Fine Pitch: Detunes the input signal.

Reverb

GoldVerb

Diffusion slider: Sets the diffusion of the reverb tail.

PlatinumVerb

ER Scale slider: Scales the early reflections along the time axis, influencing Room Shape, Room Size, and Stereo Base.
