CollidingCombSynth is an experimental synthesizer which sounds like bowed string. Equipped with 24 Karplus-Strong string models which collide to each other. Tuning of pitch is possible, but difficult. So mostly suitable for sound effects.
CollidingCombSynth requires CPU which supports AVX or later SIMD instructions.
Set the filter to only react to the highest frequencies of the sound. You’ll see the input audio glowing behind the filter, you can use this as a guide to select the relevant frequencies. Set the ratio to around 1:1.5. Change the threshold so the audio you want to effect surpasses the threshold. The waveform itself will change colours to indicate if it is above or below 1 sample per pixel. At a Time of 1 or lower, a grey waveform display shows that more than one sample is compressed into each pixel. When Time is set higher than 1, a blue waveform indicates that the resolution uses more pixels to draw each sample. The figure below.
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
[email protected] .
Linux build is built on Ubuntu 18.0.4 and tested on Bitwig and Reaper. If you are using distribution other than Ubuntu 18.04, plugin will not likely run. In this case, please take a look at build instruction.
InstallationPlugin
Place
*.vst3 directory to:
DAW may provides additional VST3 directory. For more information, please refer to the manual of the DAW.
Presets
Extract preset zip, then place preset directory to the OS specific path:
Preset directory name must be the same as the plugin. Make
Uhhyou directory if it does not exist.
Windows Specific
If DAW doesn’t recognize the plugin, try installing C++ redistributable (
vc_redist.x64.exe ). Installer can be found in the link below.
Linux Specific
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.
macOS Specific
When trying to run plugin first time, following message may appear on macOS.
In this case, open terminal and try running following command to unzipped
.vst3 directory.
Plugin may be considered as unsigned/un-notarized application. In this case, try following the steps below.
Beware that steps above degrades security of your system. To revert the settings, follow the steps below.
ReferenceColor Configuration
At first time, create color config file to:
Below is a example of
style.json .
Vst Plugin To Detect Changes In Waveform Above Threshold The Number
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.
Controls
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.
Snapping is not available for all BarBox. If you’d like to have snapping for certain BarBox, feel free to open issue to GitHub repository.
Edit One Bar with Shift + Right Drag holds a bar under the cursor when mouse right button is pressed. Then only changes that one bar while holding down mouse right button.
Toggle Lock with Ctrl + Shift + Right Drag behaves as line edit. When right mouse button (RMB) is pressed, it holds the opposite state of the bar below mouse cursor, then use the state for the rest of bars. For example, if RMB is pressed on a locked bar, dragging unlocks bars while holding down RMB.
Caution
Output amplitude varies a lot, even if
Compressor is turned on. Recommend to always insert limiter after CollidingCombSynth.
