Modular Freedom

VSTForx is a full-modular effect network creation tool which comes as a VST-plugin. With VSTForx you are able to load any number of VST-plugins and connect them anyway you want.

Additional modules allow you to manipulate such signal chains and offer a whole new way in mixing and producing.

Plugin chain example
Parameter network example

Advanced Controls

Build complex controler chains by creating parameter networks composed of arbitrary plugin parameters. With special audio-transformer modules it’s possible to control parameters with audio events.

Available Features

Basic Features

  • Free Plugin Chaining

    Unlike many other plugin chainers you are able to build effect chains similar to "real" circuits. With that you have more control on how your sound is created.

  • Free Parameter Binding

    Every effect and every module is controlled by parameters. All of these parameters have a knob representation which can be placed and controlled on the main "circuit" view. With the knobs you are able to bind parameters together, so that every parameter changing will be transmitted to its neighbours.

  • Connection Operators

    are modificators for parameter value transmissions. Available operators are Inverse, Logarithmic, Exponential, Multiplier, Min/Max and Offset.

Internal Modules

Besides the plugins VSTForx knows three types of modules: the signal processor, the signal switch and the signal transformer.

  • Input/Output Switches

    are able to switch between several states while every state belongs to an input or output. An "Input Switch" for example can switch several inputs to one output. A "selector" parameter controls the switch state. Furthermore several parameters control the "fade-in / fade-out" behaveiour.

  • Input/Output Step Switches

    Unlike the "I/O Switches" the "Step Switch" state is not controlled by a parameter. The states will be iterated automatically. Either with a fixed time per state or synced to the beat of your DAW.

  • The ADSR Trigger

    generates an ADSR sequence triggered by an audio signal. This sequence will be transformed into an output parameter value. Thus it's possible to control parameters (or rather the connected units) with any audio input.

  • Remote Channel

    offers (system wide) signal communication between VSTForx instances. So it's possible to send an audio stream from a VSTForx instance in Ableton Live to a VSTForx instance loaded in Cubase. Just as it works for audio data, it's possible to transmit parameter values.

  • VSTForx further modules

    Further Modules

    Volume, Pan, Peaktracker, MIDI Receiver

  • Script module symbol

    Script Modules

    give you the opportunity to write user specific modules in the - easy to learn - Lua language. Lua is fast enough to implement own signal processors or sound generators. Furthermore you can write scripts to manage the view and its elements.

OS Support

VSTForx is available for Windows and Mac.

Ok.. Thanks, I get it. But your method doesn't trigger the LFO exactly as needed, it just modulate its depth, right ? A pity ! I need absolutely to trigger the lfo with big accuracy. Aniway, I'll use a lfo coming from ouside pc modular system. I gonna use VSTForx a bit like silentway but in the other direction : from outside computer --> vst.

Thanks ! Your stuff is very great ! And if I can make a suggestion, please, add a triggering feature to the lfo !

Ok.... Another suggestion .... An LFO with random curve would be useful too ! ;)

…how can one trigger (an LFO) ?

The LFO runs in the conventional modes of either synced or free-running. Therefore, the phase of it is usually not adjustable. There is a trick to circumvent this, however, by tying note events to the amplitude of the LFO.

Below is a schematic which:
  • Generate audio with a synth at note on/offs.
  • Feed that audio to VSTForx' internal module named ADSR Trigger.
  • Map the generated ADSR to the LFO's Amp parameter.

The quirk with this method is that the Sustain parameter of ADSR Trigger has a timespan, as opposed to checking if input audio remains above the threshold.
That said, the LFO will fade in and out.

Alternatively, you could use host automation.

I have another question regarding the LFO : is it possible to trigger it ? And if yes, how can one trigger it ?

Thanks :)

Nice ! Excellent ! Thanks !…

You're welcome :)

Unfortunately, i'm unable to make use of the host parameters.

As of the latest release of FL Studio, this is no longer the case.

Nice ! Excellent ! Thanks ! I have another vst host, in fact ... Vienna ! And it works pretty well.
Great !

Just one little thing : the manual is enough laconic....

Quoting JoPo:
Other host ?? I don't have any !

ie. Another VST host. MiniHost Modular and Podium Free are great, the former simply requires registering with the site.
Use them to load VSTForx and do a plugin scan. The scan result should save to VSTForx' config, allowing results to be accessible between hosts.
Quoting JoPo:

The LFO is found by the following procedure:
• Right-click VSTForx interface and select "Modify Scene". This opens the Scene Browser.
• Navigate the cascading menu to:
Main Scene > Plugins > Add Plugin > LUA Plugins
• Click "LFO.lua" then the "Add to scene" button at the bottom of the Scene Browser.

LUA plugins are scripts that VSTForx recognises as its own plugin format.

Anyway, I want to use it only with Lounge Lizard. I made a special folder for it ! And it works... But ....

Fast or normal scan always crash Cubase 8.5.20 ! Help ! What should I do ?

i recommend doing a scan in another host. Then load VSTForx in Cubase and plugins should be available.

…TAL Bassline (the free one), do not show an input.
A few ther synths, like TyrellN6 or MiniBit, show an input.
What's going on here? HELP

Though i'm not on a 64bit system, and only tested the TAL Bassline, i'm unable to replicate your bug.
i'm able to access hosted plugin's audio inputs and outputs, even if there are multiples of those. i'm able to set MIDI channels per instrument using the parameter found in Modify Scene-->(VSTi)- ->midi config. The multi-outs of VSTForx also works as expected.
Here is a screenshot of those functions:
