Orra Audio “Orra Press” – Next-Gen Multi-Mode Compressor With 6 Freely Arrangeable Engines – $49
The companion plugin Orra Link (for sidechain sending) is also bundled with the main product.
2. What is Orra Audio “Orra Press”?
Orra Press is a completely new concept multi-module serial compressor that lets you freely arrange 6 dynamics engines across 6 reorderable slots.
Traditional compressors followed the “one engine, one workflow” principle. Mix engineers normally open one comp to shape tone, another to control dynamics, and yet another plugin to limit – jumping between plugin windows until they lose track of which knob they turned and why.
Orra Press rethinks this from the ground up, allowing 6 different dynamics engines – VCA, Optical, FET, Multiband, Spectral, and Limiter – to be stacked serially within a single window. Slot order can be instantly rearranged with arrow buttons, and the same engine can be loaded into multiple slots (e.g., 3 stages of shallow Classic at 2dB gain reduction each). A single plugin lets you build “a chain tailored to the song.”

6 Dynamics Engines
Each slot can freely select from 6 engines, including duplicate loads. Switching engines on a slot preserves your dialed-in settings, so you can audition freely.
SLOT 1 Classic VCA-STYLE / ZERO LATENCY
A workhorse VCA compressor. Feed-forward VCA with stereo-link peak detection, soft-knee static curve, and standard attack/release. Predictable and transparent – a reliable second-stage choice for buses, vocals, and chains. Use it for: drum bus glue, vocal smoothing, second stage in chains.
SLOT 2 Optical OPTO-STYLE / PROGRAM-DEPENDENT
Opto emulation prioritizing feel over precision. Dual-stage release (fast for isolated peaks, slow for sustained activity) with a soft initial ratio that climbs as you push harder. Switchable between Compress and Limit modes. Use it for: vocal leveling, bass guitar, 2-bus glue in Limit mode.
SLOT 3 FET AGGRESSIVE GRAB / ALL MODE
Fast-attack FET style with input-driven engagement. The harder you push the INPUT knob, the harder it drives, with a tanh saturation stage that scales with gain reduction. ALL mode (all buttons pressed) replicates British-mode chaos with ratios over 20:1. Use it for: parallel drum room, vocal peak control, snare top transient grab.
SLOT 4 Multiband 4-BAND LINEAR-PHASE FIR
A 4-band compressor using a linear-phase FIR crossover network. All bands share the same group delay, eliminating inter-band leakage. Crossover handles can be freely dragged, with each band’s threshold line visually displayed on the spectrum. Use it for: de-essing, full-mix mastering glue, kick/bass separation.
SLOT 5 Spectral FFT-DOMAIN / PER-BIN
Frequency-domain compressor working across roughly 1,000 independent FFT bins. The Resonance control targets only narrow-band ringing peaks while passing broadband content through. The Focus handle restricts the frequency range being compressed. Use it for: snare ring suppression, vocal de-harshing, dynamic killing of room modes.
SLOT 6 Limiter MASTERING-GRADE / TRUE-PEAK / LUFS
A mastering-grade brickwall limiter with soft-clip pre-stage, lookahead, parallel fast/slow release, ISP (inter-sample peak) prediction, and ITU-R BS.1770 compliant true-peak detection. Three styles (Clean / Warm / Smash) and three quality tiers (4x / 8x / 16x) are switchable. Use it for: final brickwall in mastering, loudness boost on stems, transparent peak control.
3-Step Workflow: Load → Reorder → Compare
01 Load: Choose Empty / Classic / Optical / FET / Multiband / Spectral / Limiter from each of the 6 slot dropdowns. Switching engines on a slot does not overwrite settings – go from Classic to FET and back, and your dials remain.
02 Reorder: Use the < > buttons on each slot card to instantly move it forward or back in the chain. Parameters travel with the slot, so settings are never lost. Build intuitive chains – fast and aggressive first, then Limiter at the end.
03 Compare: Headers A / B / C / D snapshots capture the engines, parameters, chain order, and SC routing of all slots. Switch instantly for A/B comparison – they’re saved with the project and presets.
Sidechain System: Orra Link Bundled
One of Orra Press’s greatest features is its fully independent sidechain source per slot. Directly above each slot’s knob area is a SIDECHAIN source dropdown offering three categories of sources. With the bundled companion plugin Orra Link, you can bypass the host routing entirely and use any track in the session as a sidechain source.
Three Sidechain Modes Per Slot
| Off | Default. Standard compression using its own input as the key. |
| External | Host’s dedicated stereo Sidechain bus. Source sent to the plugin’s SC input in the DAW drives detection (e.g., kick → bass ducking). |
| Link 1 – 36 | The 36-channel sidechain supplied by Orra Link. Insert Link on any track, select a channel, then reference it from any Press card. |
All 5 compressor engines (Classic / Optical / FET / Multiband / Spectral) support sidechain. The Limiter slot is designed without sidechain, so the SIDECHAIN dropdown itself is hidden.
Operating Orra Link
Orra Link is a small sender-only plugin that broadcasts the audio of its host track onto a numbered Link channel, placing it on a shared bus that can be read by every Orra Press instance in the project. The UI has just three controls:
| CHANNEL | Dropdown to select Unassigned, or Link 1 through Link 36. |
| SEND | Toggle that mutes broadcasting at the source side while keeping the channel assignment. |
| OUTPUT | Gain knob that adjusts only the sidechain send gain stage without touching the source track’s fader. |
The status pip in the header indicates whether the current channel is broadcasting – shown as Live (broadcasting) or Bus unavailable (see notes below).
Basic Operating Flow
STEP 1 Insert Link on the source: Insert Orra Link on the source track and select a channel number (e.g., Link 1) from the CHANNEL dropdown. If the status reads “Live,” it is broadcasting.
STEP 2 Open a Press slot: Insert Orra Press on the track you want to sidechain, and open the SIDECHAIN dropdown at the top of the target slot.
STEP 3 Select the same channel: Choose the same channel number (Link 1) as step 1 – the source signal then drives that slot’s detector.
Visualization on the Analyzer
When sidechain is active, a red SC strip is added above the GR strip in the Scope (filled from the top – taller means louder SC). In the Spectral view, the per-bin GR display is replaced by an FFT view of the sidechain, so you can see at a glance which frequency components of the sidechain are cutting the main signal. The Multiband spectrum is color-coded by current per-band SC drive amount.
Multiband and Spectral Also Support Sidechain
Multiband splits the sidechain with its own FIR crossover bank, with each band’s detector keyed by the corresponding SC band. Spectral runs a parallel FFT on the sidechain, allowing the main signal to be cut at the frequency space where the sidechain has energy.
Usage Notes
Latency: Orra Link introduces a one-audio-block latency between sender and receiver. Because DAWs are unaware of this cross-track dependency, block order is undefined – in the worst case audio from one block earlier is used (a trade-off common to cross-track sidechain plugins).
Sandboxed AU hosts: Some DAWs run AU plugins inside a sandbox, which can block Orra Link’s shared-memory connection. In that case the status reads “Bus unavailable,” but Link passes audio transparently and nothing breaks. When it doesn’t work, fall back to the host’s External SC bus.
Other Features
Mix Knob for Parallel Compression: Every engine has a Mix knob. Setting an aggressive 30-50% completes parallel compression inside a single instance – achieving the “New York” drum technique without an aux bus.
16 Factory Presets: Vocals (Tight FET / Smooth Opto / FET + Opto / Spectral Polish), drums (Gentle Glue / Parallel Crush / Punchy FET on kick), bass (Classic Control / Multiband Tight), master (Transparent Glue / Opto + Classic / Final Limiter Light), Spectral utilization (De-Resonate / Broadband Tame) – all covered.
Per-Slot Oversampling: Off / 2x / 4x / 8x can be set per slot for the detector and gain stage. The Limiter exposes three tiers – Standard (4x) / High (8x) / Ultra (16x) – delivering tight ISP-aware true-peak control.
Tracking-Friendly: Classic / Optical / FET operate with zero latency when oversampling is Off, so timing does not shift even when inserted during recording. Multiband / Spectral / Limiter introduce latency, but it is automatically compensated by the host’s PDC (Plugin Delay Compensation).
