Next Generation Audio Routing  


vxPlug has been developed to control plug-ins (effects and synths) in a multitrack setup from just one plug-in editor window. vxPlug can load VST plug-ins within a host application with the ability to:

  • Control plug-ins from a single user interface.
  • Define the point where audio processing takes place in a flexible manner.

vxPlug consists of 2 plug-ins: vxPlugControl and vxPlugClient.



vxPlugControl loads VST plug-ins and controls their parameters. Host parameter automation and MIDI are supported. Click the image above for a screenshot of vxPlugControl.

There are two ways to set up the routing of the audio data:

  • You can route audio through vxPlugControl and through selected plug-ins. In this configuration, vxPlugControl works like a chainer. vxPlugControl also supports parallel processing.
  • Alternatively, the point of processing audio in your host application can be defined by vxPlugClient. Every instance of vxPlugClient is able to send and receive audio data to/from vxPlugControl. Within vxPlugControl, the audio data is routed to plug-ins you have loaded before.

Both routing options can be mixed (switchable for every plug-in).

To minimize screen usage, vxPlugControl offers a small Knob Page.

You can use up to 16 instances of vxPlugControl and up to 128 instances of vxPlugClient. vxPlug is VST 2.4 compatible.

Examples of Usage

  • Use your favorite track EQs during mixing while controlling the EQs from one single user interface. To measure the results in realtime, MultiInspector will be of great help. vxPlug in combination with MultiInspector works like an advanced multitrack EQ with spectrum analyzer.
  • Check audio effects at different points in the effect chain of the host application by simply switching the audio connection in vxPlugControl. No effect unloading and reloading needed.
  • Setup measurement points in the effect chain and switch between them.
