Live sound software for macOS
Shadow Rack runs your VST3 and AU plugins live, laid out like the channels of a console - no clicks when you change things, and back in seconds if a plugin crashes. Add 3D in-ear mixes your musicians run from their phones - and with the WING Extension, your Behringer WING drives the whole system.
Your studio plugins on every channel - and peace of mind at the show.
Every musician hears the band around them - and mixes from their phone.
Set a Behringer WING as the interface - and the desk becomes part of the rack and the in-ears.
A plugin host that looks like a console: channels, inserts, sends and meters. Hook it up to your desk over USB (or any interface) and mix with the plugins you know from the studio.
Scribble strips, inserts, sends and meters - just like on your desk. Mono and stereo channels, buses, mains, and New York buses in their own section.
Open a channel and you see all its plugins in order - each with a preview, its latency and its CPU load. Right next to them, the window of the plugin you picked, scaled up to fill the screen.
Add, remove, move or bypass plugins while the band plays. Each of these fades in smoothly over 12 ms - no click. Bypass switches to a dry signal delayed exactly like the plugin, so nothing jumps in time or phase.
When a plugin crashes, Shadow Rack restarts in a few seconds with the same session it had before. The plugin that caused it is switched off straight away, so it can't happen again. With the WING Extension, the channels play straight from the desk in the meantime.
You see exactly how much the Mac adds, how long the whole loop through the desk takes, which channel is the slowest and whether there were dropouts. If the CPU has room to spare, it tells you how far you can bring the buffer down.
The real app, step by step - pick what you want to see.
Every musician hears the band placed around their head - using HRTFs measured on a real human head. It's easier to hear yourself, so the stage can be quieter. Musicians set their own mix from their phones, and you never leave the desk.
Music: "Roulette" by Tom Ray · CC BY 3.0 · the band's own tracks, the chorus looped
Sources: rack channels after their plugins, or straight from the interface.
Musicians scan their code and get their mix in the phone's browser.
3D, stereo or mono - each musician picks how they hear it.
Runs in its own process: if the rack stops, the in-ears switch to the raw inputs at once.
Everyone on one screen, one click into a mix, and the bass dragged to where the singer can hear it.
All your musicians on one screen - for each one you see how their band is placed, which mode they listen in and their level. Click a musician and you're in their mix.
Drag each source to where it stands on stage - or wherever it's easiest to hear. Closer is louder; higher lifts it above the rest.
Each musician gets a code. They scan it with the camera and their own mix opens in the browser - nothing to install, nothing to log in to.
Take the rack's channels after their plugins, or any input on the interface - a talkback mic, an ambience pair. Names and colours match the rack.
With the WING Extension, the in-ears work hand in hand with the desk: they hear any desk channel, the mixes leave straight through the desk's outputs - and if the in-ear engine ever stops, the WING keeps the musicians going.
Channels that don't go through the rack are right there, straight from the desk: one click and they're in the in-ears, raw - the WING sends them to the Mac over USB by itself. Put one through the rack later and the in-ears switch to it after its plugins.
Pick where each musician's mix leaves the desk - LOCAL, AUX, AES50 A, B, C or AES/EBU. Shadow Rack routes the USB return to that output and names it after the musician, in their colour. Repatch it at the desk and the app follows.
Give every musician a backup: a bus on the desk, picked right next to their output. If the in-ear engine is gone for more than 1.5 seconds, their output switches to that bus on the WING - they keep hearing the band - and switches back once the engine returns.
Rack FX and Rack IEM work with any audio interface - the same way on every one. With this add-on, you set a Behringer WING as the interface, plug in its network cable, and everything below switches on by itself. Buy it once, it works in Rack FX and in Rack IEM.
On the full-size WING, Shadow Rack writes three pages to its custom controls - FX, NAV and SHOW - and makes sure they stay there (load a show or restart the desk - they're back in seconds). Four knobs and eight buttons work on the channel you pick with SEL; the names show on the desk's screens and whatever's on lights up. Watch - or take over.
The plugin you're on: its knobs bank by bank (on an EQ: the band you touched), FINE, BYPASS, previous / next plugin, WINDOW, TAP.
CH, PLUG, ADD and PRESET on the knobs; CH BYPASS, BYPASS, INSERT, LOAD, UNDO, WINDOW, DELETE, REDO. INSERT, LOAD and DELETE ask first - press twice.
The channel's New York sends on the knobs, each on / off; CH BYPASS, SPEECH (reverbs, delays and NY off - and back), PANIC, TAP.
Pro-Q 3 / 4 and F6: click a band in the plugin's window - FREQ, GAIN, Q and DYN of that band are on the desk. Nothing to program. Try it below.
Click a band in the EQ - the desk's knobs are on it. Turn a knob and the plugin follows.
Under each plugin, a strip of the four WING knobs. Press LEARN, touch a control in the plugin, turn the knob on the desk - done. Up to 16 named banks per plugin, remembered across sessions.
Pick a WING channel and press RACK: Shadow Rack finds a free USB output and input, sets the channel's ALT source with automatic switching, creates the rack channel - and shows it all the way the desk does. Buses and mains go through a free FX slot as an insert. It never overwrites an insert or ALT source you already use.
The rack's channels take the desk's names, colours and icons. Rename a channel in the app and the desk shows it too, including the USB return. SEL on the desk opens that channel in the rack.
One button on the top bar switches every rack channel from THROUGH RACK to DIRECT - they then play straight from their inputs on the desk. And if something goes wrong, the desk switches itself.
It uses the WING's own built-in Precision Limiter: one press on a main puts it in a free FX slot, last before the speakers, and sets it up for you - ceiling, attack, release. Play it as loud as the PA takes, press SET - nothing gets past that level. It runs on the desk, so it protects the speakers even without the Mac.
A smooth fade on every bigger change while the band plays - adding, removing, moving or bypassing a plugin.

No. Rack FX and Rack IEM work with any Core Audio interface and any MIDI controller - the same way on each. The WING Extension is everything that switches on when the interface is a WING on the network: routing, names and colours, the desk's custom controls, SEL, the safety switch, the speaker limiter and the in-ears from the desk.
The VST3 and Audio Unit plugins you already own. You add the ones you want; each one is tested in a separate process before it gets into the rack, so a broken one never reaches your show.
Shadow Rack restarts by itself within seconds with exactly the same session, and switches off the plugin that caused the crash so it can't happen again. With the WING Extension, the channels play straight from the desk in the meantime. The in-ears (Rack IEM) run separately and switch to the raw inputs at once.
No. Each musician scans their code with the phone's camera and their mix opens in the browser. The phone only controls the mix - the sound goes to their in-ears through your interface and transmitters as usual.
Yes - on its own Mac (say, at the monitor desk) with any interface, or next to Rack FX on the same Mac, where it can take the rack's channels after their plugins.
One licence, three Macs, yours for good. You activate each Mac once - online, or with a file for a Mac that never sees the internet. It never checks anything in the middle of a show.
Everything, for 30 days. Use it on a real show before you decide.
The trial is the full product, so try first. A licence is digital content delivered at once - you confirm at checkout that the 14-day withdrawal doesn't apply once it's delivered. If it doesn't work as described, write to us and we'll make it right.
