The Ultimate Mixing Tool  


FaderWorks is an audio plug-in for multi-instance gain and latency adjustment. The main idea behind FaderWorks is to provide an additional layer of control and flexibility to a mixing environment.

Digital audio workstations are usually equipped with a mixing console capable of leveling and routing of audio signals. FaderWorks enhances this concept by adding volume and logical switching controls for a virtual routing of audio signals.

At its simplest, FaderWorks can be placed anywhere in the effect chain of an audio track. This allows you to specifically control the volume behind or before other audio plug-ins.

The main idea behind FaderWorks comes to life when 2 or more instances are opened. These instances can be connected logically to each other. Using FaderWorks in this way, it is possible to manage complex mix setups with just one volume fader.

In addition, FaderWorks provides controls for adjusting and compensating latency within a multitrack setup (PDC).


How It Works

Every instance of FaderWorks is assigned to a group. By default, all instances belonging to the same group have identical volume levels. Moving the volume fader in one instance simultaneously changes the volume of all other instances in the same group.


The relationship between groups is configured via the integrated connection matrix, available in every instance. Therefore, the connection settings can be updated immediately without switching to another plug-in instance.

Connections are defined between a source group and a destination group. There are 2 connection modes available:

  • Crossfade with a default crossover level of -6 dB. This level can be changed to avoid an increase or a decrease of volume at the crossover point, e.g. because of phase cancellation.
  • Multiply & Offset - based on the source volume, the destination volume is calculated by multiplying the source volume with an adjustable factor and then adding the specified offset.

Connections can be cascaded, e.g. group 1 depends on group 2, whereas group 2 depends on group 3. Changing the volume fader of any connected group simultaneously changes the volume in all connected groups according to the connection settings, e.g. moving the volume fader in group 2 updates the volume of group 1 and of group 3.

FaderWorks incorporates solo, mute & bypass functionality known from mixing consoles. For efficient virtual signal routing these switches work on 3 different logical layers.

Just one click is needed to mute or bypass all instances. These are global switches that can be activated from any instance.

For flexible selection of active groups and instances, every instance is equipped with 2 solo/mute/bypass switch combinations. The first one is for switching groups and the second one is for switching the current instance with respect to all other instances in the current group.

Individual instances can also be bypassed without affecting other instances.

All volume levels are adjusted with the volume fader. There are 4 different fader modes available:

  • Volume for calculation in the connection matrix (the default).
  • Group offset.
  • Individual offset.
  • Sum of the levels mentioned above.

The effective volume applied to the audio signal is determined from the sum of the first 3 components listed above. Individual offset and group offset can be switched on and off for every instance.

FaderWorks provides a generic concept to handle Plug-In Delay Compensation (PDC). It is an efficient, deterministic and sample accurate approach.

You can setup a database of plug-in names and latency values which is shared between all instances. Place one instance of FaderWorks on every track and switch the appropriate latency values off or on.

CCs as well as pitch bend and aftertouch can be assigned to gain parameters, offset switches and solo/mute/bypass switches. For gain parameters, several mapping curves and value ranges are available. Ideal for external control surfaces.


Examples of Usage

Combining the features of FaderWorks, numerous mixing scenarios are possible. A few examples:

  • Dynamically assigned virtual aux tracks that overlap logically.
  • Quick A/B-comparison of newly recorded tracks - single tracks or a group of tracks can be crossfaded or switched against each other.
  • Enclose selected audio-plugins by 2 connected instances of FaderWorks for achieving an "overdrive" effect with simultaneous control of the overall volume.
  • Selected vocal tracks of a choir can be increased in volume while at the same time the volume of all other choir tracks is reduced and vice versa.
  • Plug-In Delay Compensation for hosts without this feature.
  • Plug-In Delay Compensation when using external hardware with your DAW.
