5. Band Processing Modes
Each of Orra EQ's 16 bands can operate in one of five processing modes. The curve visualization changes color: white for EQ, gold for saturation modes.
Oversampling for saturation modesv1.2.1
The header Oversampling control (Off / 2× / 4×) applies to every saturation band — Orra Tube, Tape, Models, and Dynamic Saturation. Engage 2× or 4× when driving hard or working with bright source material to keep alias artifacts inaudible. Pure EQ and Dynamic EQ bands run at native rate and incur no aliasing. See for details.
Channel Processing: Mid/Side
Every band has a Channel selector that determines which part of the stereo signal it processes:
- • Stereo (default): Band processes the full stereo signal
- • Mid: Band processes only the center (mono) content
- • Side: Band processes only the side (stereo difference) content
This works with all five processing modes. You can EQ the mid channel, saturate the sides, or apply dynamic EQ to just the center -- all within a single plugin instance.
Any of these methods can be used to set a band's channel:
- • Right-click any band and select the channel from the context menu
- • Use the Channel dropdown in the side panel
- • Press C to cycle through Stereo, Mid, Side
Separate Mid and Side response curves are drawn on the display in amber and teal.
Mode 1: EQ (Traditional Equalization)
Transparent, surgical equalization with extended range and precision.
Parameters:
- • Frequency: 10Hz to 22kHz
- • Gain: -60dB to +30dB

6. Settings Panels & Tabsv1.2.1
The settings panel sits to the right of the EQ display and is always visible — it's permanent furniture, not a pop-out. Because it never collapses, the EQ display stays at a constant width and your band positions don't shift around as you work.
Behavior
- •Auto-open: selecting a band automatically opens the right view for that band's mode — Zones for EQ, Tape settings for Tape, Saturation settings for Models, Dynamic settings for Dynamic EQ, Dyn Sat for Orra Tube.
- •Tab memory: each band remembers its last visited tab, so jumping between bands restores what you were looking at.
- •Graceful fallback: if a tab no longer applies after a mode change (e.g. you switch a band from Tape to EQ), the panel falls back to the mode's default tab.
- •No band selected: the panel displays a rotating tips carousel — a quick refresher on shortcuts, mouse modifiers, and workflow features. Tips fade in and out every ~8 seconds.
Tab Layout
The panel header has up to two rows of tabs. Click any tab to switch the view; tabs highlight to show which view is active.
Row 1 — Mode-Specific
- • Orra Tube: [Dynamic]
- • Tape: [TAPE | Dynamic]
- • Models: [Models | Dynamic]
- • Dynamic EQ: [Dynamic]
- • EQ: row omitted entirely
Row 2 — Always Available
[Zones | Piano] — available on every band, regardless of mode.
Tab Reference
- •TAPE — tape model, speed, and noise reduction
- •Models — saturation type, Tone, Bias, and type-specific parameters
- •Dynamic — in saturation modes: dynamic saturation enable, threshold, range, attack, release. In Dynamic EQ mode: attack, release, threshold, ratio
- •Zones — vertical strip of frequency regions (SUB to AIR) with a gold indicator showing where the band sits
- •Piano — vertical scrollable piano with the band's nearest key highlighted
7. Piano Viewv1.2.1
A vertical scrollable piano keyboard, available on every band as a Row 2 tab in the settings panel.
- •Lays out all 88 standard piano keys plus extended octaves, so the full 20 Hz – 20 kHz range is reachable
- •The key that matches the selected band's frequency glows: green when perfectly in tune with a note, fading to yellow as the band moves off-pitch
- •Smooth crossfade animation when the active key changes
- •Mouse-wheel scrolls; the view auto-recenters on the active key whenever you change a band's frequency to a different note
- •Compact readout at the top shows Hz, note name, and cents off
Great for tuning drums, finding harmonic resonances, snapping bands to musical pitches, or just keeping a musical sense of where you're EQing.
8. Zones Viewv1.2.1
A vertical problem-zone strip showing the frequency regions every mix engineer ends up thinking about. Zones is the default settings tab for EQ-mode bands.
A gold indicator line shows where the selected band's frequency sits. Useful for a quick gut-check of what you're working on — especially helpful for less experienced ears or for sanity-checking the frequency you just dialed in.
9. Sidechain for Dynamic EQv1.2.1
Each Dynamic EQ band has its own Sidechain source picker in the right panel, directly under the Channel dropdown. Select what audio drives the band's level detector — independently per band. Duck the mud band off the bass DI, dip the boxy band off the snare, and ease the harsh band off the lead vocal, all at once, off three different sources, in one plugin instance.
Sidechain Modes
Off (default)
The band detects on its own input. This is the classic dynamic EQ behavior: a bandpass filter at the band's center frequency feeds the detector, so the band only reacts to energy in its own frequency neighborhood. Use Off when you want the band to self-trigger (de-essing, resonance taming). Existing sessions are unaffected.
External
The band detects on Orra EQ's external sidechain bus. Route any track in your DAW into the sidechain input, and the band reacts to that signal's full-band level. Use External when you want a kick to trigger a low-shelf cut on the mix bus, a snare to duck a harsh band on guitars, and so on.
Link 1–36
The band detects on an Orra Link channel. Insert the Orra Link plugin on a source track, set it to a channel number, then pick that same channel number here. Works across busses, tracks, and groups regardless of whether your host supports flexible sidechain routing.
Frequency-Independent Detection
When the band uses an External or Link sidechain, the detector bypasses the band's own bandpass — it reads the full sidechain signal directly. Moving the band's frequency knob doesn't change how the kick triggers it; the frequency knob only controls whichfrequencies get ducked. This matches the convention in Pro-Q 3, Pro-MB, and other modern dynamic EQs. In contrast, self-detect mode (Off) keeps the frequency-conscious bandpass behavior — the band only sees energy near its own center frequency.
Routing an External Sidechain in Major DAWs
Logic Pro (AU)
Insert Orra EQ on the destination track. Above the plugin window, click the Side Chain dropdown and pick the source track or bus.
Pro Tools (AAX)
Insert Orra EQ on the destination track. In the plugin window header, click the Key Input (Side Chain) selector and pick the source bus.
Ableton Live (VST3)
Insert Orra EQ on the destination track. Click the wrench icon (top-left of the plugin window) to expose the device's sidechain panel, then set the SC source.
Reaper (VST3)
Insert Orra EQ on the destination track. Click “2 in 2 out” in the title bar to show the routing matrix, then route extra input channels (3 / 4) from your source track.
Cubase / Studio One (VST3)
Insert Orra EQ, click the side-chain activate icon in the plugin header, then send the source track to the resulting send.
Sidechain Any Track via Orra Link
Orra Link is a free sidechain companion plugin that bypasses DAW routing entirely. It writes audio into a shared memory region with 36 numbered channels, and any Orra EQ band can read from any of those channels.
To use Orra Link
- 1.Insert Orra Link on the source track (the track whose audio should trigger the band)
- 2.Set Orra Link's channel number (1–36)
- 3.In Orra EQ, pick the matching Link N entry in the band's Sidechain dropdown
Why use Link instead of External
- • DAWs differ in sidechain routing flexibility — some don't let you sidechain across bus types. Link bypasses all of that.
- • One source can feed multiple receivers across multiple plugin instances.
- • Different bands of the same Orra EQ can pick different Link channels — duck different bands off completely different sources.
Liveness, fallback & latency
- • If an Orra Link sender stops (track removed, plugin disabled, host crash), the band falls back to self-detection within ~340 ms. Audio keeps flowing — no stuck gain reduction, no buzz.
- • Zero added latency on the receiver side. The detector envelope follower's existing ms-scale time constants smooth over the standard one-block intrinsic Link latency below perceptual threshold.
Tips
- • Many bands, many sources: insert Orra Link on the kick, snare, and lead vocal, set them to channels 1/2/3, then on your mix bus pick Link 1 for the low band, Link 2 for the mud band, Link 3 for the harsh band. Three independent ducks, one EQ.
- • Stereo vs mono SC: mono SC drives both detectors; stereo SC drives left/right detectors independently.
- • Input gain doesn't affect SC level: the input-gain knob in the meter panel scales only the main signal, never the sidechain input.
- • Snapshot/preset capture: the SC source choice is saved with presets, snapshots, and project state.
10. Oversampling for Saturation Modesv1.2.1
A global Oversampling control in the header lets you reduce aliasing artifacts on any saturation band (Orra Tube, Tape, Models, Dynamic Saturation).
Off
Native sample rate. Lowest CPU. Suitable for tracking and lighter drive amounts.
2×
Doubles the internal sample rate during saturation. Cleaner highs and less aliasing audibility on hot drive settings.
4×
Highest fidelity. Use on hot saturation in mastering or when the source has lots of high-frequency content.
The setting persists with the project. It has no effect on pure EQ bands or Dynamic EQ bands — those run at native rate and incur no aliasing. The Bit Crusher and Wavefolder benefit most from 4× when used aggressively.
11. Advanced Features
Solo, Bypass, Delta, and Hide Curve
S - Solo Mode
Mutes all other bands so you can hear only what this band is doing to the whole signal. Perfect for identifying problem frequencies by sweeping with gain boost.
B - Bypass Mode
Disable this band while keeping it in the chain. Useful for A/B comparison.
D - Delta Mode
Hear ONLY what the band removes or adds. Extremely powerful for surgical resonance removal and verifying de-essing.
H - Hide Curve
Hides this band's curve visualization while still processing audio. Useful for decluttering the display.

17. Troubleshooting
"Orra EQ not showing up in DAW"
- • Rescan plugins in DAW preferences
- • macOS: Check AU validation in Audio MIDI Setup
- • Windows: Verify VST3 path is scanned
- • Try: Restart DAW, restart computer
"License validation failed"
- • Check internet connection
- • Verify license key was entered correctly
- • Contact support if persistent
"Sound is distorting/clipping"
- • Check input/output meters
- • Reduce input gain if input is clipping
- • Reduce overall EQ gain (multiple boosts add up)
- • Verify gain structure in DAW
- • For saturation modes, try engaging 2× or 4× oversampling
"Sidechain isn't working"v1.2.1
- • For External: confirm your DAW is actually routing audio to Orra EQ's sidechain input — most DAWs require explicit sidechain routing via the plugin header
- • For Link: confirm Orra Link is inserted on the source track, enabled, and set to the same channel number as the band's Sidechain dropdown selection
- • Confirm the band is in Dynamic EQ mode — the Sidechain dropdown only affects Dynamic EQ bands
- • Confirm the band's Amount > 0 and the Threshold isn't set so high that no signal triggers it
18. What's New in v1.2.1v1.2.1
This update brings the largest workflow refresh since launch, plus a complete sidechain system. Everything is additive — existing sessions load unchanged and unaffected.
Per-Band Sidechain for Dynamic EQ
Every Dynamic EQ band gets its own Sidechain dropdown: Off / External / Link 1–36. Each band can independently key off a different source — duck the mud band off the bass DI, dip the boxy band off the snare, and ease the harsh band off the lead vocal, all at once. Zero added latency; frequency-independent detection (Pro-Q 3 / Pro-MB convention) for external/Link, classic frequency-conscious behavior for self-detect.
Sidechain Any Track via Orra Link
Orra Link is a free sidechain companion plugin that exposes 36 named sidechain channels via shared memory. Insert Link on the source track, set the channel number, then pick that Link N in any Orra EQ band's Sidechain dropdown. Works across busses, tracks, and any DAW routing without host-specific limitations. Senders that stop heartbeating drop off receivers within ~340 ms — the band falls back to self-detection so audio keeps flowing.
Oversampling for Saturation Modes
A new Oversampling control in the header lets you reduce aliasing on any saturation band: Off / 2× / 4×. Setting persists with the project.
Auto-Opening Settings Panels & In-Panel Tabs
Adding or selecting a band now automatically opens the right settings panel for that band's processing mode — no more hunting for the controls. The 120 px settings slot is now permanent furniture, so the EQ display stays at a constant width and band positions don't shift. Panel-selector tabs moved into the settings panel itself, laid out in two rows; each band remembers its last visited tab.
Tips Carousel
When no band is selected, the settings slot displays a rotating tip carousel — a quick refresher on shortcuts, mouse modifiers, and workflow features. Tips fade in and out every ~8 seconds.
Piano View
A vertical scrollable piano keyboard, available on every band. The key that matches the selected band's frequency glows: green when perfectly in tune, fading to yellow as the band moves off-pitch. Great for tuning drums, finding harmonic resonances, or snapping bands to musical pitches.
Zones View
A vertical problem-zone strip — SUB / BASS / MUD / BOXY / BODY / HARSH / SIBILANCE / AIR — with a gold indicator showing where the selected band's frequency sits. Default settings tab for EQ-mode bands.
Workflow & UI Polish
- •Mode changes now snap the active tab back to the mode's default panel, so you don't accidentally land on Piano or Zones when you switch a band to Tape and miss the tape controls.
- •The DynSat tab is now reachable in Orra Tube mode — previously it was the only option and got hidden when you tabbed to Piano/Zones.
- •The Dynamic settings tab is reachable in Dynamic EQ mode after visiting Piano or Zones.
- •Fixed ghosting where leftover controls from a previously open panel would linger briefly after switching bands via the EQ display.
- •Settings panel close buttons removed (panels are permanent furniture now).
- •Cleaned up Unicode rendering in numeric readouts so cents and other suffixes display correctly across every macOS font stack.
- •Mode-change transitions no longer flash visible-but-empty panels.
