VST digital mixer

AudioStation’s mixer is the very first live mixing digital console with integrated VST technology.

Unlike other mixers, Audiostation can not only mix signals from microphones and external instruments, but actually activate and mix in its own channels your VST software instruments, and effects which can then be applied to microphones or external and software instruments.Il mixer digitale VST

The type of console configuration is 20/8/2 - in other words 20 input channels, 4 auxiliary channels and 1 Master stereo channel.

The layout and graphical interface are made to resemble a traditional mixer, which makes operations extremely easy and intuitive, even for novice users.

Channel types

The console features 6 different types of channel:

Channels 1-8

These are monophonic channels that can be used to mix microphones and external instruments connected to analog inputs 1-8, and/or software instruments enabled in VST inserts. These inserts can even hold software effects to process signals from external devices and software instruments.

When necessary these channels can be coupled in stereo mode: 1+2, 3+4. 5+6. 7+8.

Channel 9/10

This is a stereo channel that can be used to mix signals from external devices connected to an S/PDIF stereo digital input, and/or  software instruments  activated in the VST Inserts. These inserts can even handle software effects to process signals from external devices and software instruments.

Channels 11/12, 13/14, 15/16, 17/18

These are stereo channels dedicated to VST instruments - hence they don’t feature audio inputs.  Software effects can be activated in the channels’ Inserts, to process signals from software instruments.

 

Channel 19/20

This stereo channel is fed by the digital audio player integrated in the console. As with the other channels, audio signals can be processed by software effects activated in its VST Inserts. It is also possible to activate VST instruments in these inserts.

Channel Aux 1-4

These stereo channels receive signals sent from channels 1-20 via auxiliary sends 1-4 (and their panpots). These can be used to activate software effects in common with any channel, or for custom channel monitoring. It is also possible to activate VST instruments in these these channels’ inserts.

Master channel

Usually this channel receives signals from every console's channel, and is used for global adjustments. In its Insert Slots are activated software effects to be applied to signals mix, and, when needed, VST instruments can be activated too.

Channel strip

Every channel in the console features these items:

VST Insert Slots

There are 4 Inserts for VST effects and instruments, that can be connected in series, in parallel or a combination of both - as explained at the VST Player page.

Insert VST

It is remarkable that AudioStation Inserts operate in stereo even with mono signals.

Actually, mono signals are split in a way that we named “pseudo-stereo”, to apply stereo effects even to mono instruments.

 

Equalizer

There is a 3-band parametric EQ, each band with adjustable: gain (+/-4dB); frequency (from 20 to 20K Hz); Q-factor; hi-lo shelving and peaking filter switches.

Equalizer

There is a 75Hz 12dB/Oct hi-pass filter too, useful to suppress stage noises.

 

Aux Send

There are 4 auxiliary sends (Aux), each one sporting a panpot, Pre/Post Fader selector, and Bypass.

AUX sends

Thanks to the stereo mode and panpot knob, there are actually 8 separate Aux buses available.

 

Panpot, Volume, Output

Each channel has a panpot; volume, with adjustable automatic fadeout; selectable channel audio out, that can be routed to master or individual outs.

Panpot, volume and output

There is a level indicator, with range adjustable between -48 and -96dB, visualization mode as Peaking or RMS, and LED Clip.

Other important channel items

In addition to the features described , every console channel has important additional items as follows:

Channel-level MIDI patchbay

Beyond the possibility to assign to any single mixer channel one or more MIDI Ins/Outs, every channel is equipped with a powerful MIDI patchbay, sporting an advanced routing and processing system, to route streams to plugins as needed.

Details are available at the MIDI Patchbay page.

Real-time plugins control

As detailed at the VST Player page, and separately for each VST Insert, there is a sophisticated system to control the plugins’ automated parameters in real-time with any kind of MIDI controller.

More details are available at the VST Player page.

Patches and Performances

An important operational aspect of the AudioStation digital mixer is the possibility to independently save each channel’s settings (channel patches), channel patch combinations together with general console settings (performances), and their use in live sessions.

Patch

Just like a synthesizer or an effect unit, any mixer channel (including the Aux ones) holds a good 1000 memory locations to store and instantly recall its settings, including MIDI routing and mapping, and whatever combination of instruments, sounds and effects it uses.

Along with each patch, plugin preset banks are saved as well. This ensures that patches will work seamlessly even in those cases where some presets are substituted with others.

Performance

The master channel can also hold 1000 memory locations to store and recall its own settings and the global settings. Each memory stores the Master channel settings and the settings for the whole console, in particular:

  • Master channel parameter settings

  • Global settings for: Tempo; Global MIDI Routing; MIDI Patch Change; MIDI Slave; Fadeouts; some others

  • Mono/Stereo state for channels 1-8

  • The audio bus/output that each channel feeds into

  • Channel labels and labels assigned to devices connected to MIDI inputs and outputs

  • The patch number for each of channels 1-20 and Aux 1-4.

This specific operational mode allows, for instance, to set specific performances for each song. When a performance gets loaded, it loads in each mixer channel the patches chosen by every musician, along with global effects, settings for monitoring and any audio track to be played.

At any time during the performance and in a completely independent way, each musician will be free to load different patches - for example, to perform a solo or other.

For a better transition between scenes, when a new performance is loaded it replaces only patches different from the ones being used. This way, channels that don’t need changes will continue to work seamlessly.

Preload

The preload function reduces patch loading times to zero. It is most useful with very complex setups or with the so-called Sample Player plugins, that use libraries of very large audio samples. While a patch is being used, another one can be loaded in memory and then activated at the right time, without delays.

Selecting Patches and Performances

Patches and performance can be comfortably selected with LiveControl (the handy remote controller included in AudioStation) or via MIDI.

Selection with LiveControl

With LiveControl it is extremely easy to recall performances and channel patches.

Selection is made easier by two buttons, Prev and Next, which directly recall the previous and next setup.

The desired setup is chosen by means of those buttons and the Data knob - even when another one is in use - and loaded at the right time with a simple click.

For further details please read the Live Control page.

Selection via MIDI

Any musician connected to the console can change patches for his channels and performances with his own master keyboard, a foot controller or any other kind of MIDI controller.

Like in a synthesizer or an effect unit, every channel of the AudioStation mixer responds to Program Change and Bank Change MIDI messages. A single program change or a combination of bank and program change determines which patch or performance to recall, and the MIDI channel 1-16 determines which mixer channel will be targeted.

Hence, independently from global and channel MIDI routing settings, performances and channel patches can be changed from any available MIDI input.

Moreover, when two or more channels are used together to create a more complex setup, they can be grouped together and recall their patches with a single command.
