Architecture and Signal Flow

In Trilian there are two main types of FX racks: those that work within a single Part and are saved with a Patch (Part FX Racks), and those that are shared by multiple Parts and saved with a Multi (Multi FX Racks).

PART FX RACKS

Using effects units, ranging from simple EQ and dynamics processors to creative effects chains, can be a crucial ingredient of any Patch in Trilian. To access the FX Racks for a Part, select a Part in the header and then select the FX button.

There are three types of FX racks in a Part: LAYER, COMMON, and AUX.

LAYER FX RACKS

Each Trilian Part contains two Layers, and each Layer in a Part has its own independent FX rack.

Before the Layer Racks feed the Common Rack, their output can be sent to the Part Aux Rack via the Aux Send mini-slider.

Using the Layer FX Rack Aux Sends

The Layer Rack Aux Send mini-sliders and PRE/POST switch are used to send signal from the output of the Layer FX Rack to the Part Aux Rack.

When set to POST, the amount of signal sent to the Aux Rack is relative to the Layer Level: if the Layer Level is turned down to zero, no signal will be sent to the Part Aux Rack. This setting allows the proportion between the original signal and the one sent to the Aux Rack to remain constant.

When set to PRE, the Layer’s signal is sent to the Aux Rack before the Layer Level fader on the Layer Page. This means the signal sent to the Aux Rack will remain constant based on the Aux Send level, regardless of the setting of the Layer Level. This setting is most useful when you want to hear the signal processed by the effects in the Aux Rack without hearing the original.

COMMON FX RACK

Every Layer’s signal is fed into the Common FX Rack, so effect units inserted in the Common FX Rack affect all Layers. The Common Rack can use its “AUX SEND” mini-slider in the top right to send audio to the AUX rack. Both the Common FX Rack and the Part FX Rack feed the Part Output.

*The Aux Send fader can be MIDI-learned and/or modulated with a controller such as the Mod Wheel. You can place a reverb in the Aux Rack (with the Aux Return fader above zero), assign the Mod Wheel as a Modulation Source to control the Aux Send fader and use it to add reverb to a Patch.

AUX FX RACK

Effects units in the Part Aux Rack can receive signal from the Layer Racks and the Common Rack via their respective Aux Send faders. The Aux Rack feeds into the Part Output and its output level is controlled by the Aux Return mini-slider. This rack is most commonly used for adding ambience processors, such as reverbs and delays.

With a total of 16 available FX units in each Patch, you have tremendous flexibility in utilizing and routing Trilian’s extensive collection of FX.

MULTI FX RACKS

A MULTI in Trilian has four Aux FX Racks and a Master FX Rack. Multi Aux FX racks can be useful for sharing the same reverb or delay across multiple parts through the Mixer Aux Sends, which can help optimize your computer’s resources. The Master FX Rack is the final FX rack in Trilian’s signal path and is useful for adding EQ and dynamics processors that affect all parts.

You can access the Multi FX Racks by selecting the MULTI tab in the header and then selecting the FX button.

NOTE: The Master FX Rack processes the Multi Aux FX Racks and all parts that are routed through output A. Parts assigned to outputs B-I are not processed by the Master FX Rack.

In summary, a MULTI can have up to 20 FX Units loaded in the MULTI FX racks, plus 8 Parts containing up to 16 FX Units each. This means a fully-loaded MULTI can have as many as 148 active FX Units in 21 Racks loaded at once. Of course, actually running that many simultaneous FX would require a very powerful computer!
