# Mixer The Mixer provides detailed controls for every track in your project. It's a panel that expands from the left side of the track list, giving you access to volume, panning, effects, and routing for each track. To open or collapse the Mixer, click the Mixer icon in the main toolbar, or use the shortcut M.

## Mix Your Tracks Using Mixer When the Mixer is open, you will see a channel strip for the Master track and for every track in your project. Master Track is always located at the very top of the Mixer. It controls the overall output volume of your entire project and features a single volume fader. Track Channels Below the Master Track, each track has its own channel strip with the following controls: * Fader: Controls the track's volume. Drag the fader up or down to adjust the level. Double-click the fader to reset it to 0 dB. * Pan: Adjusts the track's position in the stereo field (left or right). Drag the knob left or right. Double-click to reset it to the center. * Solo S: Mutes all other tracks, allowing you to hear only soloed tracks. You can solo multiple tracks at once by holding Ctrl / Command. * FX: Opens the Effects Panel for this track. * Input Channel: Selects the audio or MIDI source for the track. The available options depend on the track type: * For Audio Tracks: Choose from the available input channels of your connected audio interface. * For MIDI Tracks: Select a connected MIDI device and a specific MIDI channel. You can choose between Polyphonic and Monophonic input modes in vocal tracks. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
