An easy one to start with. This is what everyone wants when asking for “aux busses”. Any audio desk has them: they allow to send a variable amount of the signal from a given channel to an effect unit, and mix the processed audio back with the unprocessed audio to the main mix.

We set up a rack with two audio input modules, and a main bus routed to our main outs. We add a second bus, that will become the aux bus that hosts our reverb plugin in the bus insert. We must set the dry-wet mix to “full wet”: we don’t need to add the dry signal at the input of the reverb unit to the original dry signal. To set up the aux routing, we must use 2 instances of an Aux Bus 1 plugin: one inserted in each of our input module inserts, configured to “send mode”, and one inserted just before the reverb plugin in the buss insert, configured to “receive mode”. The level fader of this instance must be set full up, and we do not need to change that any further. We’re done: by plying with the level faders in our “send” instances, we can set the desired amount of reverb for each channel separately.

We can repeat this process for each new effect we would like to add. Add as many bus modules as you need, and insert the corresponding Aux Bus plugins and effect plugins in the right places.  Each new Aux Bus should use another version of the Aux Bus plugin: Aux Bus 1 plugins intercommunicate, so do Aux Bus 2 plugins etc.

The routing described here is of the type “pre-fader”. That is because in Forte, the native module-level fader acts upon the OUTPUT of the module. That means: if you bring this fader down, the amount of signal sent to the aux bus will remain unchanged: bring it fully down, you will hear a totally “wet” processed signal. This is the usual configuration for stage monitor mixes, but suitable for effect sends: you’d want a “post-fader” configuration. To achieve that, insert a fader-plugin such as Brainspawn Automated Fader at the beginning of your input module insert chain, and use that one for adjusting channel levels. I do recommend to always use a plugin-fader for channel level control as a rule instead of the native bus output fader.

Here the advantage of a modular concept becomes obvious: you can choose exactly WHERE you are inserting your main channel fader, in other words, you can freely mix pre- and post-fader sends. A module insert chain could look like this, for exemple: Aux Bus 1 - Aux Bus 2- Automated Fader- Aux Bus 3 -Aux Bus 4 where number 1 and 2 are pre-fader and could feed 2 different stage-monitor mixes, and number 3 an 4 are post-fader sends to feed 2 different effect busses. That is more flexibility than most hardware desks can offer!
