Hidden Features of HoRNet Multicomp Plus MK2 You Should KnowThe HoRNet Multicomp Plus MK2 is a versatile multiband compressor/limiter plugin that offers much more than straightforward compression. Beyond the obvious controls — threshold, ratio, attack, release, and make-up gain — the MK2 hides several handy features and workflow optimizations that can help you shape mixes faster, solve problem tracks, and get more musical results. This article walks through less obvious capabilities, explains when to use them, and gives practical tips and examples.
1) Per-band saturation and soft clipping options
Most people load the Multicomp Plus MK2 for its multiband dynamics, but the plugin also includes per-band harmonic processing that can add warmth or tame peaks.
- What it does: Each band can apply gentle saturation or soft clipping to incoming audio. This is not a separate distortion module; it’s integrated into the dynamics processing and interacts with gain reduction.
- When to use it: Use mild saturation on low-mid bands to add body to bass guitars or synths without raising levels. Apply soft clipping on the master band for taming occasional transients before limiting.
- Practical tip: Keep saturation subtle (drive < 3–4 dB) for warmth; increase cautiously on the highest band to retain clarity.
2) Mid/Side processing per band
Multicomp Plus MK2 supports mid/side operation on individual bands — a powerful tool for modern mixing and mastering.
- What it does: You can choose to process the mid and side signals separately inside each frequency band, allowing different compression behavior for center and stereo content.
- When to use it: Tighten the mid (center) for vocals and kick while leaving more open stereo width on sides. Compress the low-mid in mid to control boxiness while leaving stereo highs airy.
- Practical tip: Use moderate settings on side channels to preserve stereo image; aggressive side compression can collapse width.
3) Filter slope and crossover tuning
Crossovers in multiband compressors are often fixed and can color audio. The MK2 provides flexible crossover slopes and tuning options.
- What it does: Adjustable crossover slopes let you set how abruptly bands are separated. Gentler slopes produce smoother transitions; steeper slopes create more independent band behavior.
- When to use it: Use gentler slopes for mastering to avoid audible banding. Use steeper slopes on corrective tasks (e.g., aggressively squashing a problematic midrange band).
- Practical tip: If you hear phase-related artifacts or a “banded” sound, try changing slope or slightly adjusting crossover frequencies to find a more musical balance.
4) Solo and listen modes for precise tweaking
Refine band settings quickly with the MK2’s auditioning tools.
- What it does: Solo modes let you isolate a band or listen to only the processed signal. Some modes also provide wet/dry auditioning for the band.
- When to use it: When identifying problem frequencies or checking how much processing is being applied to a specific band during dynamic passages.
- Practical tip: Solo a band and sweep its crossover or EQ to discover offending frequencies; switch to processed-listen to confirm the compressor’s musical effect.
5) Auto-release and program-dependent controls
Program-dependent attack/release adapts to the incoming material for smoother, more musical behavior.
- What it does: Auto-release adjusts the release time according to the audio’s dynamics. Program-dependent controls make the compressor respond differently to transients and sustained material.
- When to use it: On complex material (full mixes, vocals with varying intensity) to avoid pumping artifacts and to keep compression transparent.
- Practical tip: Use auto-release as a starting point, then nudge release manually if you need more rhythmic pumping or more glue.
6) Advanced gain-matching and level-metering
Understanding how compression affects perceived loudness is essential; MK2 includes tools to compare levels.
- What it does: Gain-matching options let you mute or automatically compensate the output so you can AB the processed and unprocessed signal at equal loudness. Comprehensive metering shows gain reduction per band and overall.
- When to use it: Always use gain-matching when evaluating compression so you avoid “louder-sounding = better” bias.
- Practical tip: Use the plugin’s peak and RMS metering to ensure you’re not pushing inter-sample peaks or misjudging perceived loudness.
7) Sidechain and key-filter features
Beyond basic external sidechain, the MK2 offers key filtering so you can compress triggered by specific frequency content.
- What it does: Key-filtering allows the detector to focus on a frequency region (or mid/side content) so gain reduction is triggered primarily by those frequencies.
- When to use it: Use a low-mid key filter to control muddiness, or a high-frequency key to tame sibilance without a de-esser. Use external sidechain for ducking instruments under vocals or kick.
- Practical tip: Narrow the key filter for surgical tasks (de-essing-like), widen it for broader tonal control.
8) Variable look-ahead and limiting behavior
For mastering and transparent peak control, look-ahead and limiter mode can be invaluable.
- What it does: Look-ahead gives the compressor a tiny preview of incoming audio so it can react before a transient hits. The MK2 also offers a dedicated limiting behavior option for more transparent peak control.
- When to use it: For mastering or bus limiting where transparent transient control is needed without aggressive attack artifacts.
- Practical tip: Use minimal look-ahead (a few ms) to preserve punch; increase only if you observe overshoots from inter-sample peaks.
9) Preset management and A/B comparisons
Smart preset handling speeds up workflow, especially with complex multiband setups.
- What it does: The MK2’s preset browser includes category tags and allows you to store snapshots, compare A/B settings, and recall previous states quickly.
- When to use it: When exploring several approaches on a mix bus or when you want quick alternatives during mastering sessions.
- Practical tip: Save a “starting point” preset for each material type (vocals, drum bus, master) so you can return to a known baseline.
10) CPU-saving modes and oversampling control
Large sessions demand efficient plugins; MK2 includes modes to reduce CPU load without sacrificing sound when not necessary.
- What it does: Turn off oversampling or enable lightweight processing modes on non-critical tracks. Oversampling helps reduce aliasing at high processing settings but increases CPU.
- When to use it: Use full-quality/oversampling on the master or final bounce; disable for tracking or less-critical buses to save resources.
- Practical tip: Toggle oversampling only for final renders or critical comparisons.
Quick workflow examples
- Tightening a vocal without losing air: Use mid/side on the high band, gentle ratio on the mid, mild saturation on the low-high band, and a narrow key-filter around sibilant frequencies to avoid harshness.
- Master bus glue with clarity: Use gentle slopes, mild ratio across bands, program-dependent release, subtle saturation on low-mid, look-ahead enabled with limiter mode off for transparent control.
- Dealing with boomy guitars: Solo the low-mid band, apply focused compression with key-filter set on the offending frequency, then add soft clipping on that band to tame peaks.
Final notes
The HoRNet Multicomp Plus MK2 is deep: taking time to explore mid/side per-band processing, key filtering, saturation, and the crossover/slope options will reveal many creative and corrective possibilities. Use the solo/listen features and gain-matching to make honest decisions, and toggle oversampling only when necessary to preserve CPU. With these hidden features in your toolkit, the MK2 can be more than a multiband compressor — it becomes a multi-faceted tone-shaping and surgical problem-solving tool.
