Mute or unmute a mixer source and set its fader.

Where
+ Add actionOBS StudioOBS: set audio+ Add actionStreamlabsStreamlabs: set audio
OBS: set audio for the source Mic/Aux with Mute set to Toggle, Unit dB, and Also set the volume on at −6 dB. Below the fields: OBS Studio connected.

Set audio controls one source in the app’s audio mixer: a mute button for your microphone, a fixed “music quiet” level, or a volume that follows a fader on your Launchpad.

Settings

Section titled “Settings”
Setting What it does
Source The audio source, as listed in the app’s mixer.
Mute Leave as is, Mute, Unmute or Toggle.
Also set the volume Off: only the mute state changes. On: the volume is set as well.
Unit dB or %. What percent means depends on the app, see below.
Volume The level to set. The slider covers −100 to 0 dB, or 0 to 100 %.
Volume from variable A variable whose number replaces the slider, for example value from a fader.

dB and percent in each app

Section titled “dB and percent in each app”
Unit OBS Studio Streamlabs Desktop
dB The volume in decibels, −100 to +26 dB. Placed on the mixer fader the way Streamlabs draws it: 0 dB and above is the top, −20 dB the middle.
% OBS’s own volume scale from the advanced audio properties: 100 % is 0 dB, up to 2000 %. The position of the mixer fader: 100 % is the top, 0 % the bottom.

When you change the unit in the editor, Lunchpad converts the slider so the level stays about the same.

How it runs

Section titled “How it runs”
  • Toggle reads the current mute state and flips it.
  • Volume from variable only counts when the variable holds a number; otherwise the slider’s value is used. A number from a variable can go beyond the slider, within the limits in the table.
  • {{placeholders}} work in the source name.
  • Errors are noted in the log and the macro goes on.

Example

Section titled “Example”

Microphone volume on a fader: create a fader named mic from 0 to 100 with the unit %, and on its Actions tab give it this action under When the level changes:

  • Source Mic/Aux, Mute Leave as is, Also set the volume on, Unit %, Volume from variable value.

For a fader from −60 to 0, set the unit to dB instead. See faders.
