 title: "AUX Sends and Buses"
 ---
 
-Route more than one module into a shared effect without forcing them through
-the same point in the chain: add a Send to each source module, aim every Send
-at the same bus, and read that bus back with a single `INSERT` or `FEEDBACK`
-downstream. Several sources feed one effect while each keeps its own place in
-the chain.
-
-A Send lives inside the module that owns it, not as a separate module: any of
-the app's 9 module types can open its `SENDS` section and add one. Each Send
-picks a bus (`AUX 1` through `AUX 8`), its own `Blend`, and an `Amount`,
-tapping that module's output onto the bus without removing it from the normal
-chain. Any number of sends across different modules can target the same bus:
-it's a many-to-one mix, not a single owner.
-
-`INSERT` and `FEEDBACK` are the two module types that can read a bus back,
-through their own `Source` Selector. Left at `Chain composite`, each behaves
-as if no bus were involved: `INSERT` runs as a plain insert stage on the
-running chain, `FEEDBACK` reads its own chain input. Setting `Source` to a
-specific bus switches either one to reading that bus's mixed content instead,
-with its own `Blend` and `Amount` controlling how it composites in. A bus
-nobody has sent to yet shows as not currently fed, and passes signal through
-unchanged.
-
-`INSERT` also carries its own Insert FX chain and its own Sends, so it can
-feed one bus while reading from a different one.
+Module outputs can be redirected, duplicated, and combined via the `AUX` buses. Every module has a `SENDS` section from which the module's output can be sent to one or more of the `AUX` buses, and an `AUX` bus can be returned at the `INSERT` and `FEEDBACK` modules via their `SOURCE` parameter. A single module can be sent to any number of `AUX` buses, and any number of modules can be sent to a single `AUX` bus. Use the `AUX` buses to split a module's output and send it to multiple other modules, or to merge the output of multiple modules at a single module.
