A proposito.Guida Utente.Contribuire.Sviluppo.Trasporto.Piattaforma. Accesso alla shellThere are 2 options for executing commands inside the container.The first option is based on libertine-container-manager exec. It lets you run your commands as root. The drawback is that the container is not completely set up. So far we know that the i.e., the /home/phablet/ directory is empty. Likewise the directory referenced in TMPDIR is not available what may lead to problems with software that tries to create temporary files or directories.You may use this option e.g., for installing packages.To execute a command you can use the following pattern. Libertine - container - manager configure - i CONTAINER - IDENTIFIER - b add - p / media / phablet / ID - OF - SD / directory / you / wantThis will not allow the container access to any of the directories earlier in the path for anything other than accessing your mounted directory.In order to use the SD-card as extra space for your container, make sure first to format it using ext4 or similar.There is a mis-feature in udisk2 that mounts SD-cards (showexec) that ensures only files ending in.bat,.exe or.com can be executed from the drive if it is (v)fat formatted.
This has been changed in other distributions allowing any file to have execute priviliges, but not ubuntu. The reccomended workaround is to add a udev rule to control how to mount a card with a given id, but since the udev rules are on the read only port on touch, this is not possible.
The first time Mixxx is started, you are asked to select a directory containing your music library. This directory will be scanned and any music found will be indexed in Mixxx's internal library. The music library path can be changed at any time in the preferences, via the Library and Playlists pane.Mixxx's preferences can be accessed by selecting Options→Preferences.When Mixxx is launched, it tries to select a reasonable sound device for output.
You can check which device Mixxx has selected in the Sound Hardware pane in the preferences.Master and Headphone Outputs. Mixxx has two audio paths: The Master output and the Headphones output. The Master output is what a DJ should have connected to their main speakers, while the Headphones output should be connected to their personal headphones. The headphone output is optional, and can be used for.To configure the Master and Headphones outputs, enter Mixxx's preferences and select the Sound Hardware pane. In order to select a headphone device, either a soundcard with at least 4 channels of output (two stereo outputs, as featured on 5.1 soundcards) or two separate stereo soundcards is required. The output channel mapping, which determines the physical jack on the soundcard that the audio comes out of, can be selected under “Channel”.Example Soundcard ConfigurationsSingle audio device (4 Channel Soundcard) Master device: Echo Digital AudioFire4 Channels: 1/2Headphone device: Echo Digital AudioFire4 Channels: 3/4Dual audio devices (Two Stereo Soundcards) Master device: ElCheapo USB Audio Channels: 1/2Headphone device: SoundBlaster Live! Channels: 1/2 Using External Mixers.
Currently, Mixxx has no special mode for routing the output of a single deck to a separate output, which is what you need when using an external mixer. However, this behaviour can be achieved with a simple trick. Move the crossfader all the way to the left and turn the “Pre/Main” knob all the way left as well. This will give you only the pre-listen signal on the headphone output. Now, enable Cueing for the second channel by toggling channel 2's HEADPHONE button. With this setup, channel 1 will be playing on the master output and channel 2 will be playing on the headphone output. The master and headphone outputs of your soundcard should then be plugged into channel 1 and channel 2 of your external mixer.Latency.
The latency in Mixxx indicates the amount of time it will take for the audio to respond to any change in a control. For example, a latency of 36 ms indicates that it will take approximately 36 ms for Mixxx to stop the audio after you toggle the play button. Generally speaking, the lower the latency, the more responsive Mixxx will be. A latency between 36-64 ms is acceptable if you are using Mixxx with a keyboard/mouse or a MIDI controller. A latency below 16 ms is recommended when vinyl control is used because Mixxx will feel unresponsive otherwise.In order to tweak your latency, reduce the latency slider in the Sound Hardware preferences pane and experiment until you can reliably run Mixxx without hearing any crackles, pops, or dropouts in the audio. Changing your to ASIO on Windows or JACK on Linux may allow you to reduce your latency setting, but this depends on your hardware configuration.Keep in mind that lower latencies require better soundcards and faster CPUs and that zero latency DJ software is a myth (although Mixxx is capable of.
For detailed information on latency in Linux, you should consult the Web, as it's quite a complex topic. The is recommended reading, especially the section on “How should I configure my Linux 2.6 Operating System?”. Other useful resources are the Linux Realtime guide and.The first thing to try if using ALSA is to set your Master output hardware to just “default” instead of specific hardware.
(This made a huge difference on a test system with integrated Intel soundcard.) The drawback to this is that system sounds (KDE beeps and such) will now be mixed in and will come out the main output.The second thing one can try to reduce system latency is getting a realtime kernel. If you're using a binary kernel, this might be as simple as installing a realtime enabled kernel with your package manager (if your package system offers one of course).
Otherwise download kernel sources and the realtime patch for your kernel version. The patch can be found. Untar the patch to your kernel source directory, apply it and configure/install the kernel as usual.There are basically two options for configuring the use of realtime-capabilities. The first and simplest one is to use the realtime-lsm modul.
This only requires to install the kernel-modul with your package manager. After that you can load it and grant realtime privileges to particular users/groups by setting uid/gid as module options (for example: “modprobe realtime gid=18” gives realtime permissions to the audio group on my system). Unfortunately, this method is deprecated and doesn't work any longer since Linux kernel version 2.6.24).In current kernels you have to use rlimits with PAM to enable realtime priority support.
(Note: This is also the prefered method for older 2.6 kernels that might still work with the realtime-lsm modul). To use this method, edit /etc/security/limits.conf:Example: /etc/security/limits.conf.
hard rtprio 0. soft rtprio 0@audio - rtprio 99@audio - memlock unlimited@audio - nice -19The lines starting with. define default values. The “@” in @audio tells PAM that audio is a group. One can also set permissions per user by writing it without the “@”.Another great tip is to use the new BFS scheduler by Con Kolivas. This new scheduler was designed for CPUs with a small number of logical cores (1-16). It gives much lower latencies for these kinds of setups.The FAQ for the BFS Scheduler is at:.
The launchpad page for a PPA by Darxus is at:.Samplerates. Mixxx supports several different Sound APIs across Windows, OS X, and Linux.
A Sound API is a tool Mixxx uses to interact with soundcards. Some soundcards come with drivers that are provide lower latency with certain Sound APIs, so different APIs can be selected from Sound Hardware preferences pane.On Windows, ASIO is generally the lowest latency API. On OS X, CoreAudio is the best choice, and on Linux, JACK or ALSA provide the best compatibility and performance. Linux users wishing to use JACK should ensure they run the jackd daemon before launching Mixxx, otherwise JACK will not appear as a Sound API in the preferences.Vinyl Control.
Vinyl control allows a user to manipulate the playback of a song in Mixxx using a real turntable as a controller. In effect, it simulates the sound and feel of having your digital music collection on vinyl. Many DJs prefer the tactile feel of vinyl, and vinyl control allows that feel to be preserved while retaining the benefits of using digital audio.You can configure vinyl control through the Vinyl Control pane in the preferences.More information about Mixxx's vinyl control and supported hardware configurations is available on the.Input Device Selection.
Mixxx can be controlled by up to 2 decks with either timecoded vinyl or timecoded CDs. In the “Deck 1” and “Deck 2” drop-down boxes, select the soundcard(s) which your decks are plugged into. In the channel selection drop-down menu, select the channel pairs corresponding to the plug on your soundcard that your deck(s) are plugged into.Mixxx supports vinyl control input through a single soundcard with 4-channels of input (two stereo line-in jacks), or through two separate soundcards which each have 2-channels of input (a single stereo line-in jack). Vinyl control requires the use of stereo line-in jacks - Mono or microphone inputs will not work.Turntable Input Preamp.
Several different types of time-coded media can be used to control Mixxx. Configure the “Vinyl Type” drop-down menu to match what type of time-coded vinyl or CD you are using on your deck(s).The “Lead-in Time” setting allows you to set a dead-zone at the start of your vinyl or CD, where the time code will be ignored. This is useful in situations where the time code begins very close to the edge of a vinyl, which can make back-cueing over the first beat in a song tricky to do without your turntable's needle falling off the vinyl. Setting a lead-in time of 20 seconds or more helps alleviate this by giving you more room on the vinyl to cue with. It's also useful when you've worn the grooves at the edge of a control record to the point that it no longer works reliably: you simply set the lead-in so that the start of the songs begin in good groove area. You can keep doing this until you run out of groove area, thereby decreasing your record replacement frequency.Control Mode.
Mixxx supports three control types on all of the timecodes we support. “Absolute Mode” provides Mixxx with both pitch and position information from the timecode, and allows you to seek by needle dropping on your vinyl or seeking on your CDJ. “Relative Mode” takes the position to be relative to your deck's starting point, and only controls the pitch in Mixxx. It is not possible to seek using your deck in relative mode. “Scratch Mode” is an enhanced version of relative mode, and only applies to FinalScratch vinyl. Scratch mode improves performance slightly while scratching, but is not necessary for better performing timecodes like Serato. Finally, “Needle-skip Prevention” allows Mixxx to detect and ignore small changes in needle position, such as when you've accidentally bumped your turntable.
This can be advantageous in a live performance environment, but the downside is that it reduces responsiveness during scratching. Consequently, disabling needle-skip prevention is recommended for scratch performances.Signal Quality. A successful vinyl control setup hinges on good signal quality.
Many factors can affect signal quality, but the most important one is ensuring the volume level of your timecode signal is moderate. A signal that is too loud or too quiet will cause adverse performance, often characterized by a loss of position data causing absolute mode to behave like relative mode. For more information on improving signal quality and troubleshooting, please see the.Mixxx represents your timecode signal quality as a pair of real-time bar graphs. The two graphs correspond to your “Deck 1” and “Deck 2” input devices. The left-most column in each graph represents the overall status of the timecode signal. A full bar with an “OK!” indicates everything is working well.
The latter two columns in the graph represent the raw, unprocessed stereo signal coming from your decks. A good signal will appear as a pair of fluctuating green bars, each of which will be out of phase. Red bars indicate the volume is too low or two high, and the “Turntable Input Preamp” setting can be adjusted to boost the volume.DJing with Mixxx. There are two main waveform displays in Mixxx that are used to display the waveform of the songs you are mixing. These are useful because they allow you to see features in a song (like a breakdown) before you hear them. The waveform displays are aligned parallel to each other in order to make beat matching easier, as it is possible to beatmatch visually by aligning the beats that appear in each waveform.Clicking and dragging on a waveform allows you to seek through a song in both directions. The waveform display is updated in realtime upon seeking.There are two smaller waveform summary displays located adjacent to the main waveform displays.
These smaller displays show the waveform envelope of the entire song, and are useful because they allow DJs to see breakdowns far in advance. Vinyl DJs will find this familiar because quiet sections of songs can be visually distinguished when looking at a vinyl record, and this is a useful tool when planning your mixes on-the-fly.Beatmatching and Mixing. Beatmatching is the process of adjusting the playback rate of a song so that it matches the tempo of another song.
Beatmatching also involves adjusting the phase of the beats in a song so that they are aligned with the beats in the other song. Matching the tempo and aligning the beats are the two things a DJ must do to beatmatch.In Mixxx, you can match the tempo of two songs by adjusting the playback rate sliders on left and right side of the user interface. You can adjust the phase of the beats by clicking-and-dragging on either waveform display to temporarily slow down one of the songs until the beats are aligned. The temporary pitch bend buttons can also be used to momentarily adjust the playback rate, allowing you to “shuffle” the beats in a song forwards or backwards, so they can be aligned with another song.Once the tempos are matched and the beats aligned between two songs, they are said to be beatmatched. A “perfect” beatmatch is near impossible - there will always be some tiny difference in the playback rates.
A keen DJ will keep his or her ears open and listen for the beats drifting out of alignment. This has a distinct “double bass kick” sound which is often preceded by the kick weakening in intensity (as the two kicks drift out of phase). When this happens, the beats can be realigned by simply tapping one of the temporary pitch bend buttons a few times in the appropriate direction. Now get out there and make Tiesto jealous!Headphone Cueing.
MIDI controllers are external hardware devices used that can be used to control audio applications, like Mixxx. Many DJs prefer the “hands-on” feel of a MIDI controller with Mixxx because it can feel similar to using a real mixer and turntables.Mixxx can work with any MIDI controller that has drivers for your OS, as long as there is a MIDI mapping file to tell Mixxx how to understand it. Mixxx comes bundled with a number of MIDI mapping presets for the devices listed below.Often times these mappings are contributed by users, but the Mixxx team has no way of judging the quality of the mappings because we don't own the devices ourselves. There are two different levels of support for devices in Mixxx: Mixxx Certified Support and Community Support. Mixxx Certified mappings are verified by the Mixxx Team. Community Supported mappings are mappings provided by the Mixxx Community, but the Mixxx team is unable the verify their quality.Mixxx Certified Mappings.
