Effects are a great way of enhancing your productions, either to add that professional sheen or to create an unusual and distinctive sound.
There are two ways of applying effects within a DAW mixer, either you can apply them on the channel of the desired instrument or you can use a bus send and auxiliary channel.
Which of these options you choose depends on the desired result but us a general rule:
This is because dynamic processing is affecting the entire signal on that channel, i.e. a compressor is looking at the dynamic range of that instrument and changing it all.
An effect such as reverb or delay doesn’t need to affect the whole signal. It’s more likely that you only want a little reverb or a little delay and you want to be able to control how much.
Also, by using an auxiliary channel for effects, it means that multiple channels can send to that effect without needing to add another instance of the plugin on every channel. This saves processing power, helping the DAW to perform more efficiently.
