The Rack
S.A RACK
One self-contained plugin holding all twenty-one Signature Algorithms processors, chained in any order, built from a description if you like, and recalled with the session.
Free 10-day trial. The download is the whole collection, 22 plug-ins in one installer, so you can try every one; start S.A RACK's trial from inside the plug-in when you are ready. Downloading does not start it, and trying one plug-in does not start the others.

What it does
Twenty-one processors, one insert.
S.A RACK is a single plugin containing all twenty-one Signature Algorithms processors. Not approximations of them and not rack editions of them: the real production DSP and the real interfaces, compiled into one binary. A module in a rack slot is the same code, with the same interface, as the standalone plugin of that name, and it sounds the same.
Build a chain of up to nineteen, in any order. Drag one out of the library to add it, drag it by its handle to move it, and the rack shows you where it will land before you let go. Each module carries its own bypass and collapses to a strip when you want the chain in view rather than the controls.
Or describe it. Type what you want, “dreamy guitar, loads of reverb”, and CREATOR builds the chain from the rack's own processors, or loads the factory chain that is everything you asked for. The words choose the intent and the rack chooses every setting. The dice give you a different take on the same sentence, and UNDO puts back the chain you had. It runs inside the rack: no account, no network, no cost per use, and nothing you type leaves your computer.
It is not a plugin host. Nothing is loaded from a .vst3 or a .component at runtime: there is no scanning, no missing-plugin dialog, and nothing to go wrong when a session is opened on another machine. The rack either opens or it does not, and if it opens, everything in it is there.
Owning S.A RACK gives you the twenty-one processors inside the rack. It does not give you standalone licences for them: for that, the COMPLETE COLLECTION includes both.
Key features
The real plugins, not rack editions of them
Each module is the product's own editor class, the same component its standalone window puts on screen, driven by the product's own AudioProcessor, with its own factory presets. There is no second interface to fall behind and no second DSP path to sound different. Every module answers a check that the view the rack shows is the view the standalone shows, because getting that wrong once produced a complete, working interface that was simply not the product.
CREATOR: a sentence in, a chain out
Say what the sound is for and what it should do: the instrument, where it sits in the production (a master, the mix bus, a group bus), the effects, the character, the decade, the genre, or an artist whose records you have in mind. CREATOR reads it in English, Portuguese, Spanish, French, German, Italian, Japanese, Korean or Chinese (Simplified or Traditional), then builds up to eight stages from recipes written for each processor and from the products' own presets, levelled from what was measured. A word it does not know is shown to you, never guessed at, and a sentence it cannot use leaves the chain exactly as it was.
Nineteen slots, dragged into any order
Add from the library by dragging or double-clicking, move a module by its handle, remove it with one button. The insertion line shows where a drop will land while you are still deciding.
Automation that survives a drag
Host parameters are positional and permanent: nineteen slots of sixteen automatable controls plus a bypass, built once and never rebuilt. Moving a module leaves the automation lanes where they were and carries the values across, so dragging a module changes the order and not the sound. A rack that created and destroyed parameters as modules came and went would lose a user's automation the first time they rearranged a chain.
Bypass that stays in time
The rack captures its dry signal and delays it by the whole reported latency, so global bypass and global mix are blends rather than comb filters, and a bypassed rack is silent-but-punctual rather than early. Both are in force from the first block a host plays.
More than 1,500 factory chains
Fourteen categories, from vocals, guitar and drums to mix bus, mastering and sound design, each chain with its subcategory, its tags and a sentence on what it is for. The browser narrows by category, subcategory, tags and search at once; a star by the chain's name marks a favourite, and your own chains sit beside the factory's. Every factory chain was played through the real rack and trimmed until it stayed inside its level bounds.
Sized to the screen you have
FULL, COMPACT and FOCUS, or AUTO to let the rack decide from the room it has. Our faceplates are nearly square rather than the thin strips a rack workflow assumes, so at one module width one of ours is about twice as tall: FOCUS exists because of that, not as an afterthought.

- Latency
- One figure for the whole rack, set by its Latency selector: 0, 256, 1,024 or 4,096 samples, 1,024 by default. Chains are padded to it, so ordinary edits (adding, moving or bypassing a module, loading a chain) leave the host's delay compensation alone. A chain that genuinely needs more, three linear-phase EQDRIFTs say, reports what it needs.
- Factory presets
- 1600
Fourteen categories: Vocals, Guitar, Drums, Mix Bus, Synth, Keys, Bass, Master Bus, Creative, Instrument Bus, Ambient, Lo-Fi, Sound Design and Utility. Each chain names the modules it builds and says what it is for. Star the ones you use, and save your own beside them.
Worth knowing
- S.A RACK grants the twenty-one processors inside the rack only. It does not grant standalone licences for them: the COMPLETE COLLECTION includes both.
- S.A RACK is not a plugin host: it does not load .vst3 or .component files, and cannot host third-party plugins.
- CREATOR knows the words in its lists, in nine languages. A poetic or unusual description gets what its known words say, and the rest is shown as not understood.
- Nothing in the rack removes broadband hiss. Asked to remove noise, CREATOR deals with hum, rumble, mud and resonances.
- FREQDIVER needs a sidechain, routing a preset cannot make, so no factory chain uses it and CREATOR uses it only when one is connected.
