Have a distinct sense of where you’re going with your track and reference it often. Make your mixdown optimal for the post-mix mastering step. The only way to get the perfect song is to mix with a sound in mind. Mix references: all audio mixers should use them. Start mixxx and under settings change your music folder to the new one. If you want you can do a rescan to check that the music files do not turn up twice suddenly (if you are on linux, do especially check music files which where in symbolically linked directory). Check if bpm and other meta infomation like cue points are still stored with the.
Welcome to the Mixxx interface. This is where the magic happens.You are going to want to get very familiar with this interface because it isthe main way to use Mixxx. In this chapter, we present the default interface ofMixxx and describe its elements, knobs and faders.
This is the Latenight skin. It is the default skin supplied with Mixxx. Thereare a variety of other skins included with Mixxx. You should explore them allto figure out which one you prefer. This section will focus on Latenight only.
3.1. The Deck Sections¶
The deck section allows you to control everything relating to a virtualturntable deck. We are going to break this down into sections.
3.1.1. Track Information Display¶
The title of the track that was loaded into a deck is displayed on top. Thisis the same as the title listed under the Title column heading inthe Mixxx library. This information is initially loaded from the track’smetadata. If the metadata is missing, the title and artist are guessedfrom the filename.
The artist of the track is listed below. It is the same as listed under theArtist column heading in the Mixxx library.
The number at the top right is the effective BPM of the track. This isthe detected BPM of the track, adjusted for the playback rate of thetrack. For example, if the track is normally 100 BPM, and it is playing at+5%, then the effective BPM will read 105 BPM.
Hint
You can use a keyboard shortcut and tap with the beat to set the BPMto the speed you are tapping, go to Using a Keyboard for moreinformation.
By default it displays the total elapsed time in the track up to themillisecond. Clicking on the display switches to the Time Remaining view,which indicates how much time is left before the track reaches the end.Clicking the display again, both the elapsed and remaining time are shownsimultaneously in the format elapsed time / remaining time.You can change the default in Preferences ‣ Interface ‣Track Time Display.
3.1.2. Waveform Displays¶
The waveform section of a deck allows you to visualize the audio changes thatoccur throughout the track, you can basically “see” your music.
By default the waveform displays are aligned parallel to each other inorder to make beatmatching easier, as it is possible to beatmatchvisually by aligning the beats that appear in each waveform.
Mixxx default skin (Latenight) - Parallel waveforms¶
Depending on the skin, Mixxx displays either parallel waveforms (default) orseparate waveforms. Select your preferred appearance inPreferences ‣ Interface ‣ Skin.
Mixxx alternative skin (Deere) - Separate waveforms¶
Warning
If you have a slower computer and notice performance issues withMixxx, try lowering the frame rate or changing the waveform typein Preferences ‣ Interface ‣ Waveforms.
The big waveform summary shows the waveform envelope of the track near thecurrent playback position and is updated in real time. The mouse can be usedon the waveform to pause, scratch, spin-back or throw the tracks.Right-clicking on the waveforms allows you to drag with the mouse to maketemporary pitch adjustments.
Hint
You can select from different types of displays for the waveform,which differ primarily in the level of detail shown in thewaveform, in Preferences ‣ Interface ‣Waveforms ‣ Summary type.
The smaller, zoomed-out version of the waveform shows the various markerswithin the track as well as the waveform envelope of the entire track. This isuseful because they allow DJs to see breakdowns far in advance. As visual aid,the part of the track that has already been played is darkened.
Clicking somewhere on the waveform allows you to jump to an arbitrary positionin the track. Like with the Waveform summary, you can select from differenttypes of displays for the overview inPreferences ‣ Interface ‣ Waveforms ‣ Overview type.
The line on the vinyl widget rotates if the track moves. It is similar to theposition marker found on scratch records. Use the mouse on the vinyl widget topause, scratch, spin-back or throw tracks - just like a real record.When performing Loop rolls or right-clicking on thevinyl during playback, a “ghost” marker hints where the playback will continue.The Vinyl Widget is hidden by default and can be enabled in theDeck Options Button Grid.
If Vinyl control is enabled, it can optionally display the time-codedvinyl signal quality. Activate the option in Preferences ‣Vinyl Control ‣ Show Signal Quality in Skin.
Using the mouse-wheel everywhere in the waveform summary will zoom thewaveform in or out. You can choose whether to synchronize the zoom levelbetween the decks in Preferences ‣ Interface ‣ Waveforms.
Song Mixer Online Free
While mixing, various additional markers can appear on the waveforms:
Position marker: The static vertical line in the center of the waveformsummary indicates the playback point of the deck. The waveform overviewincludes a vertical line to show the current position within the track.
Beat marker: The regular white lines on the waveform summary indicate thelocations of beats in the audio, also called the beatgrid.
Cue marker: Indicates the position of the cue point.
Hotcue marker: Indicate the position and number of a hotcuepoint if set.
Loop-in/Out marker: Indicate the beginning and the end of a loop.
Loop overlay: Is drawn between the Loop-in/Out markers and changes colordepending on whether a loop is activated or not.
Track ending notification: If the waveform overview flashes red, only 30seconds are left before the track reaches the end.
3.1.3. Deck Options Button Grid¶
The six buttons at the bottom right below the waveform allow you to configurethe deck. Starting from the top-left and moving clockwise the buttons are asfollows:
Toggles the visibility of the Vinyl Widget in the Waveform Displays.
If enabled, the repeat mode will jump back to the beginning and continueplaying when the track finishes.
Clicking this button ejects the track from the deck. Alternatively you can usea keyboard shortcut, go to the chapter Using a Keyboard for moreinformation.
Clicking this button adjusts the track beat-grid so that the current positionis marked as a beat. This is useful if Mixxx was able to accurately detect thetrack’s BPM but failed to align the beat markers on the beats. Formore information, go to the chapter Beat Detection.
If enabled, all cues, hotcues, loops, and beatloops will be automaticallyquantized so that they begin on a beat.
Keylock locks the track’s pitch so that adjustments to itstempo via the rate slider do not affect its pitch. This is useful if you wouldlike to speed up or slow down a track and avoid the “chipmunk” effect thatspeeding up vocals has.
3.1.4. Playback/Cue Controls¶
Clicking the Play/Pause button starts and pauses the playback.
See also
The actual behavior of the Play/Pause button depends on theselected Cue mode.
Hint
To return to the beginning of the track, right-click on the deck’sFast-Rewind Button.
If the button is pressed while the track is playing, the play position jumps tothe Cue point on the track and the track is paused. Once the trackis paused at the Cue point, you can preview it by holding the Cue Button. If youhave not moved the Cue point yet, the default point is at the track’s beginning.
See also
The actual behavior of the Cue button depends on theselected Cue mode.
3.1.4.1. Setting Cue points¶
Every track has a Cue point, by default on its beginning. Unlike withHotcues, you can’t delete, but only move Cue points.
The Cue point is moved according to the selected Cue mode, as explained below.
3.1.4.2. Auto Cue¶
Mixxx automatically seeks to the saved Cue point on track load. If none exists,seeks to the beginning of the track.
Uncheck Preferences ‣ Interface ‣ Auto Cue ‣ Jump to maincue point on track load to always seek to the beginning of the track.
3.1.4.3. Using Cue Modes¶
Mixxx supports various Cue modes that adapt to fit other devices in yoursetup, or your personal preferences. The actual behavior of the Play, Pause, andCue buttons depends on the selected Cue mode. To change the Cue mode, go toPreferences ‣ Interface ‣ Cue mode.
Mixxx mode (default)
While paused at Cue point (Cue button lit):
Holding down the Cue button plays the track from the Cue point,as long as the button is pressed. After releasing the Cue button, the trackjumps back to Cue point and pauses again. Continue playback by pressing thePlay/Pause button before releasing the Cue button.
While paused not at Cue point (Cue button flashing):
Tapping the Cue button stores the current position as new Cue point.
While playing:
Tapping the Cue button causes the track to instantly jump to the location ofthe Cue point where it pauses the playback.
Tapping the Play/Pause button pauses the track at the current position.
Mixxx mode (no blinking)
Is the same as the default Mixxx mode, but with no blinking indicators.
Pioneer mode
It is basically the same as Mixxx mode but the buttons are more flashy like aPioneer CDJ player.
The Play/Pause button flashes once per second when a track is paused.
The Cue button flashes twice a second when the next push will move the Cue point.
Denon mode
While paused at Cue point (Cue button lit):
Holding down the Cue button plays the track from the Cue point, as long asthe button is pressed. After releasing the Cue button, the track jumps backto Cue point and pauses again. Continue playback by pressing the Play/Pausebutton before releasing the Cue button.
Tapping the Play/Pause button starts the track at the current position.
While paused not at Cue point (Play button flashing):
Tapping the Cue button moves the track back to Cue point.
Tab the Play/Pause button to start playing. The Cue point moves to theposition where the track was started.
While playing:
Tapping the Cue button causes the track to instantly jump to the location ofthe cue point where it pauses the playback.
Tapping the Play/Pause button pauses the track at the current position.
Numark mode
It is basically the same as Denon mode but without a flashing Play/Pausebutton.
This mode is useful if you want to implement a custom skin with 3-button decks,featuring a Cue button, a dedicated Pause button, and a Play/Stutter button.
CUP (Cue + Play) mode
While paused at Cue point (Cue button lit):
Continue playback by releasing the Cue button.
While paused not at Cue point (Cue button flashing):
Tapping the Cue button stores the current position as new Cue point.Continue playback by releasing the Cue button.
While playing:
Tapping the Cue button causes the track to instantly jump to the location ofthe Cue point where it pauses the playback. Continue playback by releasingthe Cue button.
Tapping the Play/Pause button pauses the track at the current position.
Hint
Use the Hotcue Controls to place more reference points on atrack.

You can also use keyboard shortcuts for Cueing. Go toUsing a Keyboard for more information.
3.1.5. Transport Controls¶
As long as the button is pressed, the track will play in reverse withincreased speed. Right-clicking on the button will seek the play position tothe beginning of the track.
As long as the button is pressed, the track will play with increased speed.Right-clicking on the button will seek the play position to the end of thetrack.
As the name suggests, this button plays a track backwards.Right-clicking on the button puts a track into reverse while being held,resumes the track and disables Slip mode when released. Useful to censorexpletives on the fly, or simply as part of your mix.
3.1.6. Vinyl Control Mode and Cueing controls¶
The Vinyl Control Mode and Cueing controls of a deck¶
The control above the waveforms relate to the vinyl control feature inMixxx and is hidden in the defaultMixxx user interface. Click theVINYL section expansion button in the mixersection, or use the specific Application shortcuts to show or hide thesection.
Abs/Rel/Const button
Absolute mode: The track position equals needle position and speed.
Relative mode: The track speed equals needle speed regardless of needleposition.
Constant mode: The track speed equals last known-steady speed regardlessof needle input.
Off/One/Hot button
This button determines how cue points are treated in vinylcontrol relative mode:
Off: Cue points are ignored.
One Cue: If the needle is dropped after the cue point, the track will seekto that cue point.
Hot Cue: The track will seek to the nearest previous hotcue point.

For more information on how to use Vinyl control in your setup, goto the chapter Vinyl Control.
3.1.7. Sync and Rate Controls¶
The rate controls allow you to change the rate at which tracks are played. Thisis very useful for beatmatching two tracks together in a mix. You cancontrol rate changes also from your computer’s keyboard, see the chapterUsing a Keyboard for more information.
SYNC button
Left-Click: Changes the rate of the track so that the BPMand phase of the track matches the other deck.
Right-Click: Only changes the rate of the track to match the otherdeck but does not adjust the phase.
Decks and samplers now pick which sync target to sync to on the fly. Decks can’tsync to samplers and samplers can only sync to decks. The sync target forsamplers is:
The first deck (in numerical order) that is playing a track with a detectedbeatgrid, and has a rate different than zero.
The first deck (in numerical order) that has a track loaded with a detectedbeatgrid, no matter if it is playing or stopped.
So basically, if you sync a sampler and both deck 1 and deck 2 are playing atrack with a beatgrid then deck 1 will win since numerically it is first. Thesync targets for decks are chosen with the new master sync feature, seeMaster Sync for more information.
The slider allows you to change the speed of the song, by default up to 10%from the tracks original tempos. The speed will increase as you move theslider up, opposite to the behavior found on DJ turntables and CDJ.Right-clicking on the slider will reset the tempo to its original value.
The percent that the track’s rate is sped up or slowed down is noted here. Isthe Pitch/Rate slider positioned at the center, the pitch rate display is at+0.0%, which indicates no change.
The plus and minus buttons increase or decrease the tempo in steps at which asong is played, same as pulling the pitch slider slightly. By right-clickingthe buttons you get even finer adjustments.
Pushing the left and right arrow buttons is like nudging the metal edge ofa turntable, or the outer edge of a CD player. It will give the track a pushor pull forwards or backwards. If the buttons are released the previous tempois restored. The buttons can act as either a fixed pitch bend or aramping pitch bend.
See also
To customize the amount by which the buttons alter the pitch ofthe track, the slider range as well as the direction, go toPreferences ‣ Interface ‣Adjustment buttons ‣ Permanent / Temporary.
Hint
If the tempo of a track changes, you’ll notice that the tone changesbased on the pitch used (e.g. playing at faster pitch gives a chipmunksound). You can enable the Keylockfeature to maintain a constant tone.
3.1.8. Loop Controls¶
In this section of the Mixxx interface you can control (beat-)loops and set theloop points of a track.
Beatlooping Buttons
Instant loop: The numbered buttons represents a different barlength. Clicking on any of that buttons will set a loop of the definednumber of beats from the beat immediately following the current playbackposition. If a loop is set, a loop overlay will be drawn on thewaveforms.
Loop roll:Right-click on any of the numbered loop buttons to temporarily setup a rollingloop over the defined number of beats. Playback will resume where the trackwould have been if it had not entered the loop.
Double loop: Clicking on the plus button will double the current loop’slength up to 64 bars. The length of the loop overlay in the waveform willincrease accordingly.
Halve loop: Clicking on the minus button will halve the current loop’slength down to 1/32 bars. The length of the loop overlay in the waveform willdecrease accordingly.
Loop Buttons
Loop-In: This button allows you to manually set the start point of a loop.A loop-in marker is placed on the waveform indicating the position.If clicked when a loop was already set, it moves the start point of a loopto a new position.
Loop-Out: This button allows you to manually set the end point of a loop.A loop-out marker is placed on the waveform indicating the position. Ifclicked when a loop was already set, it moves the end point of a loop to a newposition.
Loop: Also dubbed Reloop, this button toggles whether the loop is activeor not. This works for manually placed loops as well as automatic loops set bythe beatlooping buttons. Depending on the current status of the loop, theloop overlay on the waveforms changes color.
Hint
If you are playing inside a loop and want to move the end pointbeyond its current position in the track, click on the Loop buttonfirst and when the play position reaches the desired position, clickon the Loop-Out button.
See also
If the Quantize mode is enabled, the loopswill automatically snap to the nearest beat. This is disabled bydefault, click on the Quantize Mode Toggle to enable it.
3.1.9. Hotcue Controls¶
To jump in between different parts of a track, you can use these numberedbuttons. You can also use keyboard shortcuts, go to Using a Keyboard formore information.
3.1.9.1. Setting Hotcues¶
Clicking on a numbered button will set a hotcue at the current playposition on the track. A marker with the corresponding number will appear in thewaveform and the button will light up to indicate that the hotcue is set.
3.1.9.2. Playing Hotcues¶
While playing: Tap a hotcue button to cause the track to instantly jump tothe location of the hotcue and continue playing. If you are playing inside aloop and tap a hotcue whose position is outside of the loop, then the trackstill instantly jumps to the hotcue but the loop will be deactivated.
While stopped: Tap a hotcue button to cause the track to instantly jump tothe location of the hotcue and start playing as long as the button is pressed.Press the Play keyboard shortcut while the hotcuebutton is pressed to continue playback, then release the hotcue button.
3.1.9.3. Hotcue labels¶
You can add custom names to hotcues. Right-clicking on a selected track in thetrack list reveals the context menu.Choose Properties ‣ Cuepoints ‣ Label and add a label forthe hotcue. Press Enter , then click OK to save.
The hotcue indicator on the waveform changes to the format #:label.
3.1.9.4. Deleting Hotcues¶
To delete a hotcue, right-click on the numbered button. The marker in thewaveform will be deleted as well.
Note
Mixxx supports up to 36 hotcues per deck. By default, only some ofthem are visible in the user interface. You can customize yourkeyboard or controller mappings to use all of them.
See also
Just as with the loops (see above), if thequantize mode is enabled, the hotcues willautomatically snap to the nearest beat. This is disabled bydefault, click on the Quantize Mode Toggle to enable it.
3.2. The Mixer Section¶
The mixer section of the Mixxx user interface allowsyou to control how the different decks and samplers are mixed together.
3.2.1. Channel Faders and Level Meters¶
In the center of the mixer section are 4 level meters. Thetwo outer-most level meters are for each deck, while the 2 inner-most levelmeters are the left and right level meters for the master output. These shouldstay at the top of the green region, with the loudest parts of the music(transients) briefly going into the yellow region. They should never be inthe red region. Refer toSetting your levels properly (gain staging)for more details.
The two large faders on either side of the level meters are the deck volumefaders, also known as Channel- or Line-faders. Adjusting these controls thevolume of each deck.
Hint
Some DJ’s prefer to use the line faders over the crossfader forfading between tracks. Try it, you may like it.
3.2.2. Section Expansion Buttons¶
The section expansion buttons on top¶
On top, and on the button of the user interface are the section expansion buttons.
If you click on either MIC, SAMPLER, orVINYL then you will enable control sections for interacting with:
You can also use the specific Application shortcuts.
3.2.3. Headphone and Master Mix Controls¶
Allows you to control how much of the master output you hear in theHeadphones output. It works like a crossfader between the stereoMaster and stereo PFL signal. If the knob is set to the left, youonly hear the PFL signal, which is the usual position for prelistening tracks.
This can be used to practice DJing with only one stereo output and a setof either speakers or headphones.
Additionally, this can be used to mix in headphones when you cannot hear thespeakers connected to the Master output and there are no boothmonitor speakers. Some DJs prefer to use this knob to mix in headphones allthe time, but many find it to be a difficult way to play. If there is only oneset of speakers and no booth monitors, you can avoid the need to mix inheadphones by setting up the speakers behind you so both you and youraudience can hear them.
Note
Don’t forget to activate the PFL button on the deck youwant to listen to in your headphones.
If activated, two mono signals are sent to the headphone output instead of onestereo signal. The master signal plays in the right channel, while the cueingsignal plays in the left channel. You can still adjust thePre/Main Knob to control the mix of the master and cue signals inthe left channel.
This knob allows you to adjust the balance (left/right orientation) ofthe master output.
The Master Gain Knob controls the gain applied to the Master output signal thatMixxx sends to your sound card, Internet broadcasting servers, and recordedmixes. Generally, this knob should not be adjusted. To change the outputvolume, a gain control should be adjusted as close to the speakers as possiblefor the best signal-to-noise ratio throughout your signal chain. Ideally, thevolume would only be adjusted by adjusting the gain on the power amplifier.On active speakers, including computer speakers, studio monitors, and PAsystems that do not require a separate amplifier, this means adjusting thegain on the speakers (which may be labeled “Volume”).
As a DJ, you may not have access to the power amplifier. In that case,adjust the volume by adjusting the gain on the equipment closest to the poweramplifier that you have access to. Typically, this is a DJ mixer. If you arenot going through a mixer, adjust the gain of your sound card. If your soundcard does not have any controls on it (for example, for sound cards built intocomputers), adjust the sound card settings with your OSmixer program. The Master Gain Knob in Mixxx should be a last resort foradjusting volume.

Warning
In no case should any part of the signal chain be clipping,indicated by a level meter going into its red regionor an LED labeled “clipping” turning on.

For an explanation of why you should set your gains this way, seeSetting your levels properly (gain staging).
This knob controls the gain applied to the headphone output signal that Mixxxsends to your sound card. Generally, this knob should not be adjusted. Toadjust the volume in your headphones, adjust your sound card’s gain on theheadphone output. Most external sound cards have a gain knob specifically forthe headphone jack. If you use an onboard sound card for your headphones,adjust the gain control in your OS mixer program.If your sound card only has one gain knob that controls both the main outputand the headphone output, then adjust the Head Gain knob in Mixxxto control the volume of your headphones without affecting your main output.
3.2.4. PFL/Headphone Button¶
The headphone button is also known as the pre-fader listen or PFLbutton and allows you to use headphone cueing. That is, it allows you to hearthe track you will play next in your headphones before your audience hears it.This helps you plan when to start the next track and manipulate it tomake it blend better with the currently playing track (for example, bysynchronizing the beats, setting a loop, or using EQs). Pressing the PFL buttonplays the track on the headphone output at full volume regardless of theposition of the crossfader or the deck’s line fader. To play a track in yourheadphones but not have the audience hear it, press the PFL button and move thecrossfader all the way to the opposite side of the deck or turn the deck’svolume fader all the way down.
Note
Headphone cueing is only available if you have configured aHeadphone Output in Preferences ‣ Sound Hardware.
Note
If you use an external hardware mixer, plug your headphones into thatrather than your sound card. Use the headphone buttons on the mixerrather than the buttons in Mixxx.
3.2.5. Equalizers and Gain Knobs¶
The gain knob allows you to adjust the gain applied to the deck.Use this to compensate for the differences in recording levels between tracks.In general, you should adjust this knob so that the track’s level meterstays around the top of the green region with the loudest parts of the track(the transients) briefly going into the yellow region. Do NOT turn theGain Knob up so much that the level meter is in the red region. At this pointthe track is clipping, which sounds bad and could damage equipment.
Note
By default, Mixxx automatically applies an additional ReplayGain sotracks have approximately equal loudness at unity gain. Your tracksmust be analyzed to takeadvantage of this feature. When an unanalyzed track isloaded, Mixxx calculates its ReplayGain value, but will not apply anewly calculated ReplayGain value to a track after it hasalready started playing (to avoid a sudden change in the gain of aplaying track).
See also
For an explanation of why you should set your gains this way, seeSetting your levels properly (gain staging).
The low, mid, and high EQ knobs allow you to change the filters of the audio.This allows you to selectively reduce or boost certain frequency ranges ofthe audio.
Warning
Be careful not to raise the EQs so much that the signal clips,indicated by a level meter being in the red region. SeeSetting your levels properly (gain staging)for a more detailed explanation.
The small boxes next to each EQ knob are called kills.Hold these buttons to fully remove that frequency range. Short click on thebuttons for latching. When in Latch mode, click again to restore the frequencyrange. If the Kill switches do not work as expected, check the high/low shelfEQ settings in the preferences.
See also
You can customize the EQ settings inPreferences ‣ Equalizer.
3.2.6. Crossfader¶
The crossfader determines the actual volume of each deck when movingthe slider from left to right. If both decks are playing and the crossfader isin its default center position, then you will hear both decks. Right-clicking onthe crossfader will reset the slider to its default position.
You can reverse the configuration of the crossfader, so that the right deck ison the left end of the crossfader and vice versa. This is also known asHamster Style. To adjust the crossfader to your style of mixing, go toPreferences ‣ Crossfader.
Hint
Using the AutoDJ feature in Mixxx, you canautomate the crossfade between the decks.
3.3. The Sampler Section¶
Samplers are miniature decks. They allow you to play short samples and jinglesbut also additional tracks in your mix. They come with a small overview waveformand a limited number of controls. All controls work just like on the regulardecks, see The Deck Sections.
The Sampler section can be hidden in theMixxx user interface. Click theSAMPLER button, or use the specificApplication shortcuts to show or hide the section.
3.3.1. Waveform Display¶
The waveform shows the various markers within the track as well as thewaveform envelope of the entire track. Clicking somewhere on the waveformallows you to jump to an arbitrary position in the track.
While mixing, some additional markers can appear on the waveforms:
Position marker: A vertical line indicates the playback point of thesample deck.
Hotcue marker: Indicate the position and number of a hotcuepoint if set.
3.3.2. Track Information Display¶
The artist and title of the track that was loaded into a sampler deck isdisplayed here.
The number at the top right is the effective BPM of the track. Tap theBPM to set the BPM to the speed you are tapping.
3.3.3. Deck Options Button Grid¶
The buttons grid next to the waveform overview allow you to configure thesampler deck. Starting from the top-left and moving counterclockwise the buttonsare as follows:
If enabled, the repeat mode will jump back to the beginning and continueplaying when the track finishes.
Clicking this button ejects the track from the deck.
This control determines the sampler input’s mix orientation.
Keylock locks the track’s pitch so that adjustments to itstempo via the rate slider do not affect its pitch.
