Pulsar Audio VM-COMP

Pulsar VM-COMP is a detailed emulation of the classic variable-bias tube compressor found in top studios worldwide. Known for its ability to deliver smooth, transparent compression and mix “glue,” it faithfully reproduces the behavior of the original hardware while adding new features for modern workflows.

Key Features

Extended Timings (New)

VM-COMP introduces extended attack and release ranges beyond those available in the original hardware.

• Faster settings allow for more aggressive and mid-forward compression styles.
• Slower timings preserve the natural, program-dependent envelope behavior ideal for bus and mastering work.
This expanded control makes VM-COMP suitable for both subtle leveling and precise transient shaping.

Complete Sidechain EQ (New)

VM-COMP includes a fully featured sidechain equalizer with a visual curve editor.

• Precisely define how each frequency band influences gain reduction.
• Prevent low frequencies from triggering compression or emphasize particular tonal areas.
• Tailor the detector response to suit complex material such as drum buses, vocals, or full mixes.
This level of control allows exact shaping of the compressor’s behavior according to the source.

Analog-Modeled Tube Compression

VM-COMP models every stage of the original circuit in detail:

• Tube and transformer stages reproduce the magnetic and harmonic behavior responsible for its smooth tone.
• Variable-mu gain reduction provides soft, musical compression even at high ratios.
• Topology Preservation Technology ensures all interactions between tubes, transformers, and control circuits behave exactly as in the analog unit.

The result is a compressor that can operate transparently, add gentle warmth, or provide dynamic movement while maintaining phase integrity and tonal balance.

Sidechain and Control Options

• External Sidechain Input – Use an independent signal to control gain reduction for ducking or de-essing.
• Mid/Side Mode – Process mono and stereo information separately for precise stereo imaging control.
• Look-Ahead / Look-Behind – Shift the detector timing to anticipate or delay response to transients.
• High-Pass, Bell, and Shelf Filters – Shape detector sensitivity directly within the sidechain.
• On-Screen Visualization – Real-time waveform and gain-reduction displays for detailed feedback.
• Low CPU Usage – Optimized algorithms allow multiple instances even in large sessions.
• Oversampling – Optional processing up to 384 kHz for higher accuracy when required.

Typical Applications

• Mastering: Add cohesive “glue” and subtle harmonic warmth without altering transients.
• Mix Bus: Smooth and unify elements while retaining low-end impact.
• Drum Bus: Create consistent punch and room ambience with adjustable timing.
• Vocals and Instruments: Add dynamic control with natural saturation and tone.
