Linux/Yabridge compatible versions

(selection)
 

Linux VST3 versions should be available at the end of 2026!
Until then it is already possible to use Wine and Yabridge, and possibly other solutions of this kind, to run some Acousmodules in this OS.

My experience with Yabridge in AV Linux MX (2024, NOT 2025) distribution is mostly positive:
- nearly all the
32 bits VST2 work nicely, but alas 32bits is no more supported by Wine ...
- regarding
64bits VST3 the DSP side works well, but there is a flickering problem on the GUI side which makes them not enjoyable and sometimes totally unusable.

I have gathered here some of the 64bits VST3 plugins that must run roughly correctly.
In general, turning off and on the GUI or hiding and showing the plugin helps to stabilize (momentarily) the flickering.

Up to 64 outputs test signals: arrange the numbered balls according to your speakers configuration (or import an "am3d" file) and Ctrl+Click on the channels numbers.
In Auto Mode you can select a specific range of outputs, the speed and the curve/direction of the cycle. And since localization can be very different according the sound's shape, you can use a continuous signal or an iterative one (with Rate and Decay parameters).
- place the speakers points in visual concordance with their spatial position (false perspective view)
- standard signal signals, a wave file can be used as the test source
- Continuous or Iterative mode with Rate and Decay settings
- Ctrl-Click on a point to generate/stop the signal
- automatic play in a selected channels Range, with Speed and Shape setting 
- import / export of the spatial configuration
Note : the Pink Noise source with the volume set at "-12dB" (peak value) matches the K-20 RMS level specs.

 

To do: direct switch without the need of a modifier key

Graphic only Peak Meters that can be visually arranged to reflect the speakers positions and activity, according to a fake 3D view.
For precise non spatial meters up to 64 channels you can use Reaper's JS meters or MCFX' ones.

The

Compact but efficient Bass Managers:
- 50 / 200 Hz crossover frequency range
- send level to up to 2/4 LFE for each input channel
- selectable crossover up to 36 dB/oct
- global Low Cut for all channels with selectable curve
- 4 (or 2) LFE outputs levels
The 18 channels version is in fact a "18.2" (20 outputs), the 36 a "36.4" (40 outputs) whereas the 64 channels version, due to the current bus size limit in most hosts, can behave as a "63.1" to "60.4" one.

 

 

Known issue: changing the filters order can generate a high level clic, don't do it during playing...

S p a c e d R o u t e

 

 

Available in two versions : in the "R" version you place the points corresponding to the speakers on the graphic and you choose what channel they receive. With the "S" version you place the sound's channels and choose to which outputs they must go.
The "R" is generally intended to be used on objects or tracks to place a sound in the spakers's space, while the "S" is more suited on the master section to adapt the space mapping to the hardware outputs.
The spatial layout is compatible with the other
Spaced plugins.
See also the
SpacedConvert which is in fact a SpacedRoute-S with two sends instead of one.

About half Acousmodules use a symbolic spatial representation of the speakers (or the inputs) positions in order to make some operations easier to do, or to allow to produce certain special effects. In all cases this kind of visualization is not meant to show the sound's space (which is something a lot more complex and subtil and must rely on hearing rather than seeing) but to configure the tools with efficiency.
In these plugins the spatial arrangement is done interactively and can be constantly modified according to the sounds and the user's intentions.
From january 2022 it is finally possible to export and import these layouts to share the raw spatial datas between different kinds of plugins -spatialization, effects, samplers, synthesizers and utilities- which can speed up their settings when they share the same speakers arrangement.
The
SpaceEditor can edit these datas in a way that may be more suitable for people who like to enter coordinates manually, and it also allows to convert the files between the 36 and the 64 channels formats, allowing actually 96 plugins to exchange their spatial configurations!
A standalone version for Windows is also provided.

It would be hard to make a simpler plugin : only one controller for 1 to 64 channels levels !
But it can be very useful to play and automate a multichannel object's volume in Reaper with a MIDI controller, or just as an intermediate gain adjustement between some plugins.

Simple multichannel wraping of RH Biquad Filter.
There is already some excellent free 64 channels EQ (MCFX, IEM) but sometimes I need a simpler yet even more effective filter, and this ones has a steepness that can go up to the 16th order !
As always :
be very cautious with the PeakGain slider...

 

Known issue: no gain compensation and limiter!

64 discreet channels hall reverb.
It cannot intend to replace a multichannel reverberation (such as the free 64 channels / ambisonics
FndReverb from IEM), but on the contrary of them that mix all the channels, this one preserves the multichannel separation. It is especially useful when doing multiple complex trajectories or when you want objects to keep their distinct spatial position and add a localized reverberation.
- very long duration up to 240 seconds (12" x 2 x 10)
- the "Mix" fader works as a "send" to allow automations without the usual "pump reverb" effect
- global Hi Frequency limit and Damp factor
- individual channels can be turned on/off (unused channels decrease the overall CPU use)
- decorelation parameter
- "quasi Freeze" button turns the duration to x20 and Mix to 100% wet
- currently Windows only... which is a shame since it is one of the more usefull plugins! Mac users stay tuned ;-)

Basic 64 channels compressor-limiter-expander.
I confess that I am very far from being a
compression lover (be it dynamic, bit rate or spatial...) but there is of course some cases where it can bring interesting or usefull effects.
This one processes each channel separately without any inter-channel linkage (thus it will not work with ambisonic encoded sounds) AND it behaves also as a dynamic expander to sculpt the sounds' material (be cautious!).
It can be used as a soft peak limiter, but don't expect the transparency and accuracy you may find in a high grade plugin like
Barricade from ToneBoosters or Reaper's plugin (up to 128 channels) ...

Use a multitouch controller that can send Polyphonic Aftertouch messages to sculpt the spectral mass of sounds up to 64 channels.
- 64 multimode filters, up to 16th order
- global touch threshold, with curve shape and inertia settings
- Weight setting for each channel, usefull with controllers that don't have even captors

 

Known issues: may need some CPU according to the number of processed filters ; since the Peak filters are not limited they must be used with caution

Its name doesn't start with "Uni" but it shared the series minimalistic UI and the unique application.
Its initial purpose was to bring subtle (or not) time decorelations on a multichannel source. In practice, it can produce a wide range of effects, from light flanger to bounce-like spatial effects, iterative lines with dramatic acceleration or deceleration curves and chaotic accumulations and resonances.
Three delay multiplicators (x5, x10, x20) allow to get long delays even when using a few channels in Liner mode, the maximum value of 10" being always the duration limit. If you need longer ones you can chain several
MiniDeco ;-)
It can process all mono or multichannel inputs and "upscales" them as needed to the full 64 processing channels and outputs. You can also use for instance only the 16 first outputs to feed a
SpatMass... the possibilities are nearly endless ;-)

It applies the same principle with up to 36/64 delay lines with independant variable speed buffer reading according to the "spot" position and size.
It application range is very vast, from sliding resonant drones to scratch-like varispeed.
- 36/64 independant delay lines
- times from 0.001" to 10"
- global feedback
- Mono input mode : use it to spread the sound over all the outputs with variable delays
- you can chain several ones to obtain complex and longer multitap delays ;-)

A sixteen taps delay where each tap is associated with a spatial point, all the sixteen ones being arranged, moved and animated as shapes and flocks among an up to 64 channels speakers system. More, these spatial structures can modulate the delay values, together with the input sound's amplitude.
- 16 independant delays up to 10" with feedback
- delays values can be set in a progressive order, linear or following an acceleration/deceleration adjustable curve and a random shift
- basic spatial shapes that can be moved, transformed and merged one into another: Sphere, Ring, Arch, Ray, Cube, Lines, Planes
- the X, Y and Z position of each spatial point and it distance from the center can modulate the Delay values
- manual selection and ordering of the delays' channels
- Flat, Decreasing or Increasing levels with acceleration curve
- Envelope Follower to modulate the Delay parameters
- Inertia setting for very slow delay/pitch evolution or harsh modulations
- integrated 16 channels TiltEQ that follow the delays height positions (Win only)
- the 36 channels version has also four LFO modulators to animate the Delay and the Shapes values

64 channels Ring Modulator.
Since all the channels share the same settings, you may prefer the following
FocusRing, but this one has the ability to mix the waveforms with a simple gesture, and can also use a variable waveform Sample&Hold as a Ring source for interesting effects...

The up to sixteen inputs are put together according to several shapes based on a sphere,  a cube, lines and planes.
Since their parameters can be combined like you want, it is possible to obtain complex 2D or 3D shapes with only a few controls, which can be of course automated.
In spite of their "nice" mini pseudo-3D view which doesn't show any speaker, these plugins will have little meaning with periphonic loudspeakers arrangements and will on the contrary relay on 2D or 3D tangible arrays.
At the difference with all other
SpatMass plugins, the 818 version has also a set of four modulators that can be connected to the important parameters, making this plugin a kind of "light" AnimaSpat version.

 

Known issue: automation works only when the plugin's UI is visible; audio drop outs may occur when automating several shapes at once in the 64 channels versions.

Above a certain number of inputs it becomes difficult to control and to automate each spatial parameter. At the same time, what we perceive becomes a global shape or area where individual elements still exist but are less and less distinct.
Unlike the
SpatMass series, the ScaleMass needs you to place each input freely in the 3D space, but when it is done they are considered as a fixed group.
- Position: move all the points in the X, Y or Z plane
- Scale: reduce the groups' size to a point, align or invert it, expand it even
outside the space, with progressive fade out based on the Areas settings
- Flocking: add organic movements and smoothness (not in the 32 inputs version)
- Wide Mode: make the sound go outside the space... and disappear
Some compromises between functionalities and efficiency are alas actually needed in these plugins:
- 864 and 2436: automation also works when the plugin's GUI is not visible; in 1664 and 3264 it must be opened
- 2436 and 3264: no "Flocking" feature to save resources
- 1664: better efficiency

 

Known issues: automation may work only when the plugin's UI is visible (see the note above).

Quite the opposite of a "spatial brush" like the Spat3D, it is a variable sized "spherical window" or "spot" that lets passing through or "illuminate" some part of the multichannel sound space, from a single pin point to its full size. Think of it as a "spatial band pass" filter.
A Shape editor allows to define how the sound's amplitude is distributed along the Focus area, whether in a gradual way, in ripples or downright chaotic.
This density variations are not represented on the discs on the views but in their value bars.
Aside to its normal multichannel use it can also process a "Mono Input", in which case it will act as a kind of advanced "panner", while in "Mono Output" mode it can behave as a "mixer".

The SpatStrument VB32 is by some aspect simpler to use than other SpatStruments since its input and output spaces are fixed: a one or two layers 32 channels grid for the inputs, and 8 points arranged in circle or cube for the outputs.
It is because its spatialization mode is quite "inverted". Instead of moving sources between output points, it is the output group which is moved inside the inputs space, like we will do in a 6DOF VR game... or in real spaces.
o it can work very well for an octophonic production, but it is mainly intended to be used in binaural, either with the internal convolution module or an external processor.
The Cube output brings support for 360° immersion, but to be honest binaural is generally not so good with elevation and the Circle seems to be better most of the time...
It can be simply played with the mouse for the horizontal plane, or better with a 3D gesture controller.
Exemples of use:
- binaural mix with movements (or octophonic spatialization) of 32 mono tracks
- replacements of the spatialization section of the SpatStrument FX24/32
- interactive play with SpatStrument A32 

Characteristics:
- 32 inputs arranged in two spatial configurations: a 2D grid with 32 points, and a two layers 16 points grid
- input channels can be freeley connected to the grid's points
- two fixed layouts 8 channels outputs (Circle and Cube)
- Scale: change the output size from a point (mono) to the more distant points
- X/Y Move, with inertia setting for very smooth
- Yaw (2D and 3D) + Pitch and Roll (3D)
- variable size and shape Area
- in 3D mode Elevation Balance and distance
- Rotation, Agitation and Orientation animators
- octophonic reverberation, with variable sends levels according to X/Y/Center points' spatial position
- integrated convolution HRTF processor, can load custom HRTF files (given Kemar, KU100 and four Rooms)
