Mixbus32C v4


Mixbus 32C is a full-featured Digital Audio Workstation (DAW) with "True Analog Mixing”™, based on the Harrison Consoles world renowned Series 32 Analog Console.

Over the last 40 years, Harrison consoles have earned, throughout the world, an enviable reputation for excellence. This is no accident. Such a level of acceptance can only be gained as a product proves its maturity through performance in the field. This real-time reputation is, without a doubt, the best measure of a product’s true worth.

Analog Performance

Harrison has pioneered the use of high performance computer technology over the last 20 years to provide unmatched processing power in the world’s largest mixing environments. By keeping up with these incremental technological steps through the decades, Harrison can now faithfully emulate the beautifully designed analog signal processing designs of the past and incorporate them into a full function “True Analog” mixing console within the digital audio workstation.

More Equalization

Mixbus 32C provides it. Each Mixbus 32C channel strip incorporates an exact emulation of the original Harrison 32C fully parametric, reciprocal four-band sweepable EQ, with second order high-pass and low-pass filters.

More Busses

Mixbus 32C provides an additional four stereo mixbus channels (12 total) each with individual level control, latency compensation, and associated master channel incorporating the highly successful Harrison tape saturation, bus compression and tone control functionality.

User Testimonial: "I love it! It's so easy to make warm, non muddy mixes. I have the time of my life in the studio these days!" - Jostein Andersen - composer/guitarist/engineer on Mixbus32C.

Mixbus 32C Features:

• Straightforward “knob per function” mixer layout based on Harrison's renowned 32C music console
• Precise emulation based on Harrison's analog console circuit designs
• Precision algorithms for EQ, Filter, Compression, Analog Tape Saturation, and Summing
• Unlimited stereo or mono input channels, each with unlimited plug-ins, sends, and hardware inserts. (limited only by CPU and disc speed)
• Unlimited MIDI tracks, each with virtual instrument support, unlimited plug-ins, sends and inserts
• Phase, Input trim, Sweepable 4-band EQ with second order HP and LP filters, Compression, and 12 Mix Bus sends on every track
• Mixbus32c has an optimized signal flow with 12 stereo Mix Buses and a master bus, all featuring Tone controls, Compression, Sidechaining, and Analog Tape Saturation simulation
• Stereo Master Bus features Tone controls, Analog Tape Saturation, K-meter, Stereo Correlation Meter, and Limiter
• Automatic plug-in delay compensation to support effects such as parallel compression without time misalignment
• Comprehensive "at-a-glance" metering with peak, peak hold, and compressor gain reduction visible on every track and bus • Extensive DAW editing features
• Industry standard plug-in support: Mixbus32c loads VST plug-ins on Windows, AudioUnit (AU) plug-ins on OSX, and LV2 plug-ins on all platforms.
• Industry standard audio I/O support: Mixbus32c uses ASIO/Directsound on Windows, CoreAudio on OSX, and JACK on Linux
• Mixbus32c provides high performance features such as LTC (SMPTE) generation and sync; video pullup/pulldown; and persistent undo (undo remains possible after closing and re­opening a session)
• Multi-core and 64-bit optimizations provide increased track counts across all OS platforms
• Fourth-generation Harrison True Analog Mixing™ processing engine with enhanced compressor/limiter algorithms; built-in sidechain bussing, and increased plug-in flexibility
• Over 50 ‘MIDI filter’ plug-ins including functions such as transposing, velocity scaling, etc
• Experimental support for video timeline, video window, and audio+video exports
• The Mixbus32c engine is internally dithered, ramped, and gain­staged so that sound quality is preserved as close to analog as possible
• Audio regions are stacked in “layers”, and every region fade­in/out is a crossfade to the region(s) beneath it
• The user interface scales to fit your monitor; larger monitors will get bigger knobs and sharper text; while small monitors (such as a laptop) are not recommended for Mixbus32C
• Refined workflow and graphics, including scaling and support for HiDPI (Retina) displays
• Incredibly cost effective because of our world-wide open source collaborators
• Generic MIDI devices can use “MIDI Learn” to assign MIDI controls directly to on-screen knobs or use MIDI profiles to select many pre-configured device layouts from a pull-down menu
• Mackie control protocol is provided for motorized fader controllers, and the Mackie protocols have been extended to ergonomically control the Mixbus channelstrip EQ, compressor, and 12 mixbus sends. Dedicated support is provided for popular devices like the Presonus Faderport, Mackie MCU, and Behringer X-Touch controllers
• OSC (Open Source Control) protocol supports ethernet-based wireless tablet controllers such as TouchOSC and Lemur for iOS and Android to remote-control Mixbus32C

The XT-EG Expander / Gate is Harrison’s versatile tool for gating noise, or gently increasing the dynamic range of tracks.

The sound of the XT-EG was derived from Harrison’s many years of developing high-end music and film tools. Like all XT plugins, the goal is to fix problems in your tracks without any unwanted artifacts. Providing an “effect” is easy; the goal of the XT series is to fix tracks without anyone knowing they needed to be fixed.

All of the common gate controls are accounted for - Depth, Hold, Attack, Release - but there are also some not-so-common tools that are typically reserved for high-end audio gear:

A Hysteresis control allows the gate to open at one level, and remain open even if the signal drops slightly below the original threshold. This can avoid chattering if the signal is very near the noise threshold.

The Lookahead control can help better prepare the gate for opening, as the plug-in can be set to see waveforms just before they reach the playhead. Adjustable times of 0ms, 5ms, and 20ms give you the freedom to gate percussive transients without creating unpleasant distortion.

The Sidechain Filter allows you to focus on a particular frequency for the gate’s detector. This can be helpful when you are trying to zero in on a particular instrument of a multi-mic recording, and is especially helpful when gating close-miced drums.

The Expander section features controls for Ratio and Knee. The Expander is useful for gently increasing the dynamic range on tracks that don’t require noise gating.

- Harrison's proprietary Expander / Gate algorithm for Mixbus.
- Expander mode provides soft expansion for vocal and dialog tracks
- Scrolling gain-reduction graph helps to tune the controls for demanding tracks
- Lookahead mode allows the gate to open before transients, preserving the attack
- Sidechain EQ allows the gate to be tuned to a particular instrument in a mix
