We all know Impact XT is cool—but it’s at its coolest when you use the individual audio outputs, because then you can add exquisite effects to individual drums.
How Multiple Outputs Work, Part 1: Impact Setup
Let’s zoom out. Impact has 16 potential outputs, which can be mono or stereo. The reason for saying “potential” is that you can use as many as you want, in whatever configuration you want—all stereo, all mono, or a mix of mono and stereo outputs.
You assign a drum to one of the 16 outputs by clicking on the little number in a pad’s lower right, and choosing from one of the 16 outputs, either stereo or mono. More than one drum can feed a single output. For example, fig. 1 shows an Impact layout for a recent song. All the drums go to their own outputs, except that Perc1 and Perc2 feed the same output because they’re going to be processed, and have their levels adjusted, simultaneously.
Part 2: Console Setup
Now we’ll have the drums show up in the console. Open the Instruments panel, click on the downward arrow, and choose Expand to see Impact XT’s outputs. You’ll see all the Impact outputs (you may have to scroll to see more than the 16 stereo outputs). They’ll have an St (stereo) or M (mono) prefix, followed by the output number. Check the box that corresponds to each output that you’re using. It doesn’t hurt to check outputs you’re not using, but they’ll take up space in the console, and serve no purpose.
Next, simplify your life by renaming the console channels to reflect the drum names (fig. 2). The names will then show up in the Instruments panel. This lets you think of the console channels as sounds instead of just outputs.
Part 3: The Payoff
So why bother doing all this instead of just using a stereo output? Because we can do all kinds of fun processing. In this example:
This processing transforms a dancehall-type beat into something more chill. The audio example’s first half plays what the loop would be like without processing, while the second half includes the processing—and that’s just the tip of the iceberg of what multiple outputs can do.
