Mixxx 2.1 released

Postby Be. » Mon Apr 16, 2018 3:29 am

After more than two years of hard work, we are pleased to announce the release of Mixxx 2.1! Since Mixxx 2.0, we have overhauled the effects system, redesigned the skins, added and improved lots of controller mappings, rewrote the audio file decoders twice, and of course fixed a bunch of bugs. Download it!

Here is a quick summary of what is new in Mixxx 2.1:
* Graphical interface scales for high resolution screens
* Overhauled Deere and LateNight skins
* New Tango skin
* Resizable waveforms
* Effects are synchronized to the tempo
* Effects are processed post-fader and post-crossfader and can be previewed in headphones
* One metaknob per effect with customizable parameter control for intuitive use of effect chains
* Nine new effects: Autopan, Biquad Equalizer, Biquad Full Kill Equalizer, Loudness Contour, Metronome, Parametric Equalizer, Phaser, Stereo Balance, Tremolo
* Loaded effects and their parameters are saved and restored when Mixxx restarts
* More transparent sounding equalizers (Biquad Equalizer and Biquad Full Kill Equalizer)
* Improved scratching sounds with jog wheels, vinyl control, and dragging waveforms with the mouse
* Simplified looping and beatjump controls
* Configurable rows of 8 samplers with up to 8 rows available for a total of 64 samplers
* Files loaded to samplers are reloaded when Mixxx restarts
* Improved volume normalization algorithm (EBU-R 128)
* Filter library table by crates
* Sort musical keys in library table by circle of fifths
* Write metadata tags back to audio files
* New JavaScript library for controller mapping
* Configure multiple Internet broadcasting stations and use multiple stations at the same time
* Broadcast and record microphones with direct monitoring and latency compensation
* Broadcast and record from an external mixer
* Booth output with independent gain knob for using sound cards with 6 output channels without an external mixer
* Prevent screensaver from starting while Mixxx is running
* CUP (Cue And Play) cue button mode
* Time remaining and time elapsed now take into account the tempo fader
* Clicking cover art now shows it full size in a separate window
* and of course, lots and lots of bug fixes.

Here are controllers with mappings that have been added or updated since the 2.0 release. Mappings marked with an asterisk (*) have been updated for the new effects interface:
* American Audio VMS2
* American Audio VMS4
* Allen & Heath Xone K2/K1*
* Behringer CMD Micro
* Behringer CMD MM1*
* Behringer CMD Studio 4a
* Denon MC4000
* Denon MC6000 Mk2*
* FaderFox DJ2
* Hercules DJ Console 4-Mx*
* Hercules DJ Control MP3 LE / Glow
* Hercules DJ Control Compact
* Hercules P32*
* Ion Discover DJ
* Korg Nanokontrol 2
* M-Audio Xponent
* Native Instruments Traktor Kontrol S4 Mk2*
* Novation Launchpad Mk1 and Mk2
* Novation Twitch
* Numark Mixtrack Pro 3 & Numark Mixtrack 3*
* Pioneer DDJ-SB2*
* Pioneer DDJ-SX*
* Reloop Beatmix 2
* Reloop Beatmix 4
* Reloop Digital Jockey 3 ME
* Reloop Terminal Mix 2*
* Reloop Terminal Mix 4*
* Vestax VCI-100 Mk2*
* Vestax Typhoon

For users upgrading from Mixxx 2.0 or older, we have a few important announcements. First, if you are using Windows, you will have to uninstall any old versions of Mixxx before you can install 2.1 (unless you were using the 2.1 beta or release candidate). How to uninstall Mixxx varies on different versions of Windows:
* Windows Vista, 7, and 8: Start > Control Panel > Programs > Uninstall a Program
* Windows 10: Start > Control Panel > Programs > Programs And Features > look for Mixxx > Uninstall

If you are upgrading from Mixxx 2.0 or older and have MP3 files in your library, we have another important announcement. The good news is that we fixed a bug where the waveforms and audio playback of MP3 files were misaligned. The bad news is that we have no way of knowing which MP3 files were affected or how much the offset was. That means that waveforms, beatgrids, cues, and loops from older versions of Mixxx may be offset by an unknown amount for any MP3 file. Only MP3 files were affected by this bug; other audio file types are unaffected. You can either correct your beatgrids and cue points manually for each track, or you can clear this information for all MP3s and start fresh. Regardless, we recommend clearing the waveforms for all MP3 files. To clear these, type "location:mp3" into the library search bar, press Control + A to select all tracks, right click, and select the information you want to clear from the menu.

In the works for Mixxx 2.2, we have a big redesign of the library GUI. Along with that will come saving & restoring search queries plus nested crates.

Want to help make Mixxx even more awesome? The biggest thing we need is more people. You do not need to be a programmer to help out. Giving feedback on the design of new features as they are being made is very valuable. Refer to the Testing page on the wiki for more information on how to get involved with that. Reporting bugs and telling us your ideas on the Launchpad bug tracker is a big help too! We cannot fix problems we do not know about, so please let us know if you find any issues with Mixxx. If you would like to help translate Mixxx into another language, refer to the Internationalization wiki page. Of course, more programmers could always help. Read the Developer Documentation on the wiki for tips on getting started contributing code to Mixxx.

We hope you have as much fun with Mixxx as we do!
Mixxx is free because it's yours!

I would like to help to translate the manual in French.
Is the manual updated to 2.1 ?
Is the Transifex site updated with 2.1 manual ?

No, they haven't yet updated the transifex translations for 2.1 for the manual. I told some of the devs to do that yesterday on zulip chat.

Oh dear!
Kudos MiXXX team, tons of work for an excellent result!
I've been using MiXXX since 2012 and v2.1 is a huge jump forward!

Great job!

Just great. Denon MX6000Mk2 works perfectly now.

So far I haven't seen any misalignment in the mp3s as you've described. Is that a definite thing that happens or are some mp3s just not affected by it?

We don't exactly know which MP3 files are affected, either CBR or VBR or both. It may also depend on how you played them with the broken decoder. I've read in their forums that Serato users reported similar issues with beatgrids and the new Pro release. Looks like at least we are in good company ;)

Glad to hear that some late night shifts prior to the release have paid of for at least one other MC6000MK2 user. Hope you enjoy it :) I had to strip off some 2.0 features to align the mapping with the components.js framework, standardization is key. This is still work an progress and will continue.

Please contact us if you discover issues, if you have ideas for new features, or if you are able to contribute in any way (development, documentation, translation, promotion, ...).

@Waverley Just noticed that you are a Mac user ;) On OS X the built-in CoreAudio framework was and is used for MP3, you might not be affected at all!

We only migrated the API of the CoreAudio decoder, but didn't update the internal implementation. In my opinion that has now become the weakest part of our decoding components and desperately needs a revamp. If you are able to do development on macOS your are very welcome! Our main development and testing platform is still Linux, myself included.

And please try beat-synchronized Echo out with post-fader effects. Big thanks to @Be for making this real!
