Orra Audio – Orra Press v1.0.1 for WiN

Multi-module serial compressor | Six dynamics processors. Six reorderable slots. One waveform at a time. Pair Classic with Spectral and then with a limiter—or any other combination you desire.

• Six processors: classic VCA, optical, FET, multiband, spectral, and limiter.
• Six reorderable slots — load any engine, change the order using the arrows.
• Independent sidechain for each slot — suppress different sources from different engines.
• Additional Orra Link plugin — sidechain for any track
• Multi-band linear-phase (4-band FIR filter) with adjustable crossovers
• FFT spectral compression with target resonance
• Master limiter with peak ISP and LUFS metering.
• A/B/C/D snapshots — instantly compare four complete plugin states.
• 16 factory presets for vocals, drums, bass, master bus, and parallel mode.
• Slot-by-slot oversampling (Off / 2× / 4× / 8×) for correct transient processing.

Six motors, one compressor

Most compressors offer a single engine and a single workflow. Orra Press offers six dynamic engines, which can be loaded into any of six slots and reordered—so the chain matches the song, not the other way around.

Traditional approach

Open one compressor to adjust the tone. Open another to adjust the volume. Open a third to limit. Switch between plugin windows. Get confused. Try to remember which knob you turned and why. There’s a separate plugin for each dynamics stage.

Orra’s Path

Place modules in the slots. Change the order using the arrows. Pair a fast FET with a slow optical transistor and a transparent limiter—or three classic transistors in a row, each providing 2 dB of gain. Compare four arrangements using A/B/C/D and release the one that wins. One plugin. Six engines. All your dynamics solutions in one window.

Three sidechain modes per slot

Off. Default. The compressor is triggered by its own input signal—standard compression behavior. External, dedicated host stereo sidechain bus. Regardless of which routes your DAW uses to determine signal routing, this is the classic action: ducking bass and drums. Link 1–36: 36 sidechain channels fed by Orra Link. Apply Link to any track, select a channel, and that source becomes available to any Press card in the project.

Visualization in the analyzer

When a sidechain is active, the analyzer displays it. In the Oscilloscope tab, a thin red SC band is added above the GR band. In Spectrum Analysis mode, the GR for each bin is replaced by the sidechain FFT, allowing you to accurately determine which frequencies in the sidechain are contributing to the main signal. In Multi-Band Spectrum mode, each band is colored according to the current SC signal.

Multiband mode splits the sidechain through its own FIR crossover bank, so the detector for each band selects the corresponding SC band. Spectral performs a parallel FFT on the sidechain, meaning you can cut out the spectral space in the main signal where the sidechain has energy. (The limiter, by design, ignores the sidechain—hard-edge limiters don’t use the sidechain.)
