Update: 2020-06-15
L4Reverb is an extended version of LatticeReverb. This time, lattice structure has 4 * 4 * 4 * 4 = 256 sections per channel.
If L4Reverb is too heavy for your machine, L3Reverb is also available. L3Reverb is a trimmed down version of L4Reverb. The lattice structure has 3 * 3 * 3 * 5 = 135 sections per channel.
L4Reverb and L3Reverb requires CPU which supports AVX or later SIMD instructions.
The package includes following builds:
macOS build isn’t tested because I don’t have Mac. If you found a bug, please file a issue to GitHub repository or send email to ryukau@gmail.com
.
Linux build is built on Ubuntu 18.0.4 and tested on Bitwig 3.1.2 and Reaper 6.03. Bitwig 3.1.2 seems to have a bug that occasionally blackouts GUI.
Place *.vst3
directory to:
/Program Files/Common Files/VST3/
for Windows.$HOME/.vst3/
for Linux./Users/$USERNAME/Library/Audio/Plug-ins/VST3/
for macOS.DAW may provides additional VST3 directory. For more information, please refer to the manual of the DAW.
Extract preset zip, then place preset directory to the OS specific path:
/Users/$USERNAME/Documents/VST3 Presets/Uhhyou
$HOME/.vst3/presets/Uhhyou
/Users/$USERNAME/Library/Audio/Presets/Uhhyou
Preset directory name must be the same as the plugin. Make Uhhyou
directory if it does not exist.
If DAW doesn’t recognize the plugin, try installing C++ redistributable (vc_redist.x64.exe
). Installer can be found in the link below.
On Ubuntu 18.0.4, those packages are required.
If DAW doesn’t recognize the plugin, take a look at Package Requirements
section of the link below and make sure all the VST3 related package is installed.
REAPER on Linux may not recognize the plugin. A workaround is to delete a file ~/.config/REAPER/reaper-vstplugins64.ini
and restart REAPER.
At first time, create color config file to:
/Users/USERNAME/AppData/Roaming/UhhyouPlugins/style/style.json
on Windows.$XDG_CONFIG_HOME/UhhyouPlugins/style/style.json
on Linux.
$XDG_CONFIG_HOME
is empty, make $HOME/.config/UhhyouPlugins/style/style.json
./Users/$USERNAME/Library/Preferences/UhhyouPlugins/style/style.json
on macOS.Below is a example of style.json
.

Hex color codes are used.
First letter #
is conventional. Plugins ignore the first letter of color code, thus ?102938
, \n11335577
are valid.
Do not use characters outside of 0-9a-f
for color value.

: Text color.foregroundButtonOn
: Text color of active toggle button. Recommend to use the same value of foreground
or boxBackground
.foregroundInactive
: Text color of inactive components. Currently, only used for TabView.background
: Background color.boxBackground
: Background color of inside of box shaped components (Barbox, Button, Checkbox, OptionMenu, TextKnob, VSlider).border

: Border color of CheckBox.unfocused
: Color to fill unfocused components. Currently, only used for knobs.highlightMain
: Color to indicate focus is on a component. Highlight colors are also used for value of slider components (BarBox and VSlider).highlightAccent
: Same as highlightMain
. Used for cosmetics.highlightButton
: Color to indicate focus is on a button.highlightWarning
: Same as highlightMain
, but only used for parameters which requires extra caution.overlay
: Overlay color. Used to overlay texts and indicators.overlayHighlight
: Overlay color to highlight current focus.Right Click on the controls pops up a context menu provided by DAW.
Knob and slider can do:
There is an additional control for number sliders used for Octave
, Seed
etc.
Control with many blue vertical bars (BarBox) have some keyboard shortcuts. LFO Wave
on Main tab and Gain
, Width
, Pitch
, Phase
on Wavetable tab are using BarBox. Shortcuts are enabled after left clicking BarBox and mouse cursor is on the inside of BarBox. Cheat sheet is available on Infomation tab.

Some BarBox has scroll bar to zoom in. Scroll bar has handles on left end and right end. To control zoom, use Left Drag on one of the handle. Scroll bar also has following controls:
Output may change with different sample rate or buffer size.
Output may blow up when both Cross
and Spread
are not 0.
Output may become loud when offset
of *Feed
is not 0, and modulation is enabled.
Output may become loud when following steps are performed.
OuterFeed
or InnerFeed
to close to minimum or maximum.OuterFeed
or InnerFeed
which was set at step 1.If the image is small, use Ctrl + Mouse Wheel or “View Image” on right click menu to scale.
Diagram only shows overview. It’s not exact implementation.
Delay time of all-pass filter.
Feedback and feedforward gain of all-pass filters nested inside of lattice structure.
Feedback and feedforward gain of lattice structure at lowest layer.
Feedback and feedforward gain of lattice structure at 2nd lowest layer.
Feedback and feedforward gain of lattice structure at 3rd lowest layer.
Feedback and feedforward gain of lattice structure at top layer.
Tip: Setting all of the *Feed
values to negative makes output more wet by blurring input signal. Especially recommend to fine tuning D4Feed
.
Multiplier for Time
and *Feed
. Useful to shorten or lengthen reverb.
Base
values are used in both left and right channel. Base
value determines the character of reverb.
Offset
values are maximum ratio between left and right channel. Amount of ratio is randomized. Changing Offset
spreads reverb to stereo.
if (Offset >= 0) {
valueL = Base
valueR = Base * (1 - Offset)
}
else {
valueL = Base * (1 + Offset)
valueR = Base
}
When Modulation
is checked, Offset
values will be randomized for each buffer. Smooth
can be used to change the character of modulation.
Pressing Panic!
button stops reverb output by setting multiplier of Time
and *Feed
to 0.
Useful to stop sounds in case of blow up.
Gain of input signal.
Gain of reverb signal.
Feedback amount from an output of lattice structure to the lattice structure on another channel. If the value is 0, signal from other channel will not be mixed.
Mid-side (M-S) signal ratio.
Following equations are used to calculate mid-side signal.
mid = left + right
side = left - right
left = mid - Spread * (mid - side)
right = mid - Spread * (mid + side)
Seed value of random number sequence.
Transition time to change parameter value to current one. Unit is in second.
