Harrison Consoles has announced the release of Mixbus v4, the latest generation of their "True Analog Mixing" workstation, featuring hundreds of new improvements, both big and small.

New User Interface

Mixbus's new and updated GUI answers user requests for better window management, and it allows the transport controls to appear above the mixer. The new "mini-timeline" allows fast and easy locating directly from atop the mixer window.

Toolbar Customization

The transport controls have been streamlined, and are configurable to hide and show the elements that are needed during the different stages of production: recording, arranging, editing, mixing and mastering. Visit Preferences->Appearance->Toolbar to turn the various sections on / off. You'll find a great opportunity for customization, while still remaining sensible and recognizable if you have to work on someone else's computer.

New Mixer Features

The latest-generation "True Analog Mixing" engine has been updated with a stereo width knob on the console mixbuses. The width knob varies from stereo to mono, and its primary purpose is to reduce the stereo width of reverb effects (similar to using a mono bus send to your reverb effects, in an analog console). After reducing the stereo width, you can pan the reverb image to one side or the other.

VCA Faders

You may create an unlimited number of VCA faders, and attach them to your tracks and buses; then you can use the VCA's fader to adjust the slave's fader level, or trigger a Mute or Solo on the slaved channels.

Input Channels (tracks and mixbuses) may be assigned to an "unlimited" number of VCAs, allowing the user to control a snare drum from 3 VCA faders: the snare, drum, and all-instruments VCA groups (for example). This flexible design is derived from Harrison's large-format console VCA implementation.

VCA and Mixbus "Spill" Buttons

The "Spill" button hides all channels except those that are attached to the VCA fader.

Mixbuses now have their own "Spill" buttons, so you can immediately show the channels that are sending to the mixbus. This is great to immediately show which channels are feeding the "Drum" bus, or the Reverb.

By combining the use of VCA Spill and Mixbus Spill buttons, you can organize much larger sessions than was practical in v3.

Recording

Global controls for track's input-monitoring, as well as improved support for pre-roll recording and several UI improvements, greatly improve the usefulness of Mixbus for tracking a live band. For example you can mouse-wheel on the metronome button to adjust the click volume, or right-click on it to take you directly to the metronome preferences.

VST Plugins on Mac

Mixbus can now load VST plugins on Mac (in addition to AU and LV2), allowing for better Mac-to-Windows-to-Linux sharing of sessions. Visit Preferences->Plugins to scan for your installed VSTs. The plugin's format will be displayed in the right-click context menus, as well as the plugin manager window.

Tempo Mapping

Following a comprehensive redesign of tempo and meter conventions, Mixbus allows the user to add tempo markers on a live show; and when desired, the tempo can smoothly ramp to follow natural tempo changes. An elegant method of editing allows you to drag the "measure lines" directly behind your transients. You don't really think about the tempo itself; just line up the measure-lines with your performance and Mixbus does the hard work for you.

Mapping the mixbus timeline to your performance can dramatically speed-up your editing and mixing process without robbing a performance of its natural timing. For example, once you've mapped a guitar-vocal recording, you can drag&drop MIDI (or a virtual drummer) into your session, and they will follow the natural tempo changes in the music.

Inline Plugin Displays

Mixbus v4 supports a new feature of the LV2 plug specification: Inline Displays. 5 example plugins are provided that utilize this new feature: a-EQ, a-Filter, a-Compressor, a-Inline Scope and a-Inline Spectrogram.

Lua Scripting

A comprehensive new scripting engine has been added which allows users to write simple scripts to modify their sessions. Scripts may be triggered from events (such as "on transport stop"). Similar to macros from Harrison's large-format consoles, a Lua script can trigger a sequence of actions. Your Lua scripts may be triggered from keyboard shortcuts or the Toolbar. You can write your own DSP or MIDI processing plugins as Lua scripts. They can even display their own icons.

Development News

Harrison say "You might have noticed that Mixbus's development is accelerating quickly. This is largely due to the rapidly increasing open-source community that we are encouraging. Over the last year, Harrison has worked to lower the barrier to entry for developing the Ardour platform so more developers can take part in the process. The new Lua scripting features are also a new opportunity for users and casual developers to take part in the development of Mixbus."

"Continuing our collaboration with the Ardour open-source community, Mixbus v4 is session-file compatible with other Ardour-using workstations: Ardour5, Waves Tracks Live, and the newly-announced iZ Session. This unusual level of inter-application support is largely due to Harrison's continued funding and support of open-source development."

"And speaking of inter-application support, you'll find something very interesting in the v4.0 release: .ptf and .ptx file import. This new item in the "Session" menu allows you to select a Pro Tools session file, and import the raw audio and MIDI data. This is a "Beta" feature that was developed by a member of the open-source community, and has limited functionality. It is provided for adventurous beta-testers only, to help us develop it further for the upcoming release of Mixbus32C v4."

Mixbus 4 costs $79. The Harrison website has been updated with a new "Specials" page, so you can always find their best offers in one place. If you are a previous Mixbus customer, you should receive an update offer via email. Mixbus32C will receive the v4 updates, plus new mixer features specific to 32C, on May 1, 2017.
