- Download CubicPadSynth 0.1.28 `macOS` - VST 3 (github.com)
- Download Presets (github.com)

CubicPadSynth requires AVX or later SIMD instructions on x86_64 environment.

`full` package contains following builds.

- Windows (x86_64)
- Linux (x86_64)
- macOS (Universal 2)

Linux build is built on Ubuntu 24.04. If you are using distribution other than Ubuntu 24.04, plugin will not likely to run. In this case, please take a look at build instruction.

`macOS` package is recommended for macOS user. I can’t purchase Apple Developer Program, therefore installation requires a workaround to bypass Gatekeeper. Details of workaround are written in Installation -> macOS Specific section.

## Contact

Feel free to contact me on GitHub repository or `ryukau@gmail.com.`

You can fund the development through paypal.me/ryukau.

## Installation

### Plugin

Move `*.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.

### Presets

Notice: Some plugins don’t have presets provided by Uhhyou Plugins.

Presets are included in the plugin package linked at the top of this page. To install presets, follow the steps below.

1. Download plugin from a link at the top of this page.
2. Extract downloaded zip file.
3. Open `presets` directory placed in extracted package.
4. Move `Uhhyou` directory into an OS specific preset directory (see below).

Below is a list of preset directories for each OS.

- Windows : `/Users/$USERNAME/Documents/VST3 Presets`
- Linux : `$HOME/.vst3/presets`
- macOS : `/Users/$USERNAME/Library/Audio/Presets`

Preset directory name must be the same as the plugin. If preset directory does not exist, create it.

- Preset Locations - VST 3 Developer Portal

### 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.

- Latest supported Visual C++ Redistributable downloads | Microsoft Learn

### Linux Specific

On Ubuntu 24.04, those packages are required.

    sudo apt install libxcb-cursor0  libxkbcommon-x11-0

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.

- VSTGUI: Setup

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

Important: `full` package is not confirmed working. When using `full`, try removing following files.

- `Contents/Resources/Documentation`
- `Contents/x86_64-linux`
- `Contents/x86_64-win`

`macOS` package doesn’t contain above files. Also, all packages are in “ad-hoc signing” state set by `codesign` command.

#### Remove Quarantine

When trying to run plugin first time, following message may appear on macOS.

    <PluginName>.vst3 is damaged and can't be opened. You should move it to the Trash.

In this case, open terminal and try running one or both of following command to unzipped `.vst3` directory. Replace `/path/to/PluginName.vst3` according to your install location.

    xattr -rd com.apple.quarantine /path/to/PluginName.vst3
    xattr -rc /path/to/PluginName.vst3

#### Bypass Gatekeeper

Plugin may be considered as unsigned/un-notarized application. In this case, open System Preferences, go to Security & Privacy → General, then click the Open Anyway button. The offcial Apple help page linked below has screenshots for the procedure. See “If you want to open an app that hasn’t been notarized or is from an unidentified developer” section.

- Safely open apps on your Mac - Apple Support

If the plugin is still not working, try changing install location to `/Library/Audio/Plug-ins/VST3/` or `/Users/$USERNAME/Library/Audio/Plug-ins/VST3/` whichever still haven’t tried.

If all the above methods do not work, try following the steps below.

1. Open terminal and run `sudo spctl --master-disable`.
2. Go to System Preferences → Security and Privacy → General → Allow apps downloaded from, then select “Anywhere”.

Beware that steps above degrades security of your system. To revert the settings, follow the steps below.

1. Go to System Preferences → Security and Privacy → General → Allow apps downloaded from, then select option to “App Store and identified developers”.
2. Open terminal and run `sudo spctl --master-enable`.

#### Applying `codesign`

Note This section may not relevant to `macOS` packages. However it’s not verified. (GitHub issue)

To use `full` package, following command might be used.

    sudo codesign --force --deep -s - /path/to/PluginName.vst3

`codesign` might not be available without installing Xcode.

## GUI Style Configuration

At first time, create color config file to:

- `/Users/USERNAME/AppData/Roaming/UhhyouPlugins/style/style.json` on Windows.
- `$XDG_CONFIG_HOME/UhhyouPlugins/style/style.json` on Linux.
  - If `$XDG_CONFIG_HOME` is empty, make `$HOME/.config/UhhyouPlugins/style/style.json`.
- `/Users/$USERNAME/Library/Preferences/UhhyouPlugins/style/style.json` on macOS.

`style.json` will be loaded for each time a plugin window opens.

Several color themes are available on the link below. To use, copy the text to `style.json`.

- VSTPlugins/package/style/themes at master · ryukau/VSTPlugins

Below is an example of `style.json`.

    {
      "guiScale"          : 1          ,
      "fontFamily"        : "Tinos"    ,
      "fontBold"          : true       ,
      "fontItalic"        : true       ,
      "foreground"        : "#000000"  ,
      "foregroundButtonOn": "#000000"  ,
      "foregroundInactive": "#8a8a8a"  ,
      "background"        : "#ffffff"  ,
      "boxBackground"     : "#ffffff"  ,
      "border"            : "#000000"  ,
      "borderCheckbox"    : "#000000"  ,
      "borderLabel"       : "#000000"  ,
      "unfocused"         : "#dddddd"  ,
      "highlightMain"     : "#0ba4f1"  ,
      "highlightAccent"   : "#13c136"  ,
      "highlightButton"   : "#fcc04f"  ,
      "highlightWarning"  : "#fc8080"  ,
      "overlay"           : "#00000088",
      "overlayHighlight"  : "#00ff0033"
    }

### GUI Scale

- `guiScale`: GUI scaling. For example, `0.75` is 75%, and `2.0` is 200%.

The minimum of `guiScale` is `0.01`. The maximum is practically non-existent (the max value of 64-bit float).

Notice: If `guiScale` is too large, DAW may place the “close” button on the plugin window out of screen, making it unclickable.

### Font Options

Following is a list of font options.

- `fontFamily`: Font family name.
- `fontBold`: Enable bold style when `true`, disable when `false`.
- `fontItalic`: Enable italic style when `true`, disable when `false`.

System font can be used as `fontFamily`. To use different fonts for different plugins, place `*.ttf` file into custom font path: `*.vst3/Contents/Resources/Fonts`.

Notice: If the combination of `fontFamily`, `fontBold`, `fontItalic` does not exist in custom font path, default font of VSTGUI is used.

If `fontFamily` is set to empty string `""`, then `"Tinos"` is used as fallback. If the length is greater than 1 and the font family name doesn’t exist, default font of VSTGUI is used.

Styles other than bold, italic or bold-italic are not supported by VSTGUI. For example, “Thin”, “Light”, “Medium”, and “Black” weights cannot be used.

### Color Options

Hex color codes are used.

- 6 digit color is RGB.
- 8 digit color is RGBA.

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.

Following is a list of color options. If an option is missing, default color will be used.

- `foreground`: 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 box shaped components.
- `borderCheckbox`: Border color of CheckBox.
- `borderLabel`: Line color of parameter section label.
- `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.

## Controls

`Right Click` on the controls pops up a context menu provided by DAW.

Knob and slider provides following controls:

- `Ctrl` + `Left Click`: Reset value.
- `Shift` + `Left Drag`: Fine adjustment.
- `Middle Click` : Rotate through minimum, default and maximum value.
- `Shift` + `Middle Click` : Take floor of current value.
  - Note: For decibel (`dB`) parameters, floor is applied after the value is converted to amplitude.

Control with many blue vertical bars (BarBox) have some keyboard shortcuts. Shortcuts are enabled after left clicking BarBox and mouse cursor is on the inside of BarBox.

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.

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:

- `Right Click` : Reset zoom.
- `Mouse Wheel` : Zoom in/out.

## Caution

Pressing `Refresh LFO` or `Refresh Table` button stop sound. They also stop all midi notes.

## Wavetable Specification

Length of a wavetable is `2^18` samples.

136 band-limited wavetables are generated for each MIDI note. Pitch bending is supported as high as 21100 Hz. 21100 Hz is derived from MIDI note number 136. Frequency of MIDI note number 137 is higher then 22050 Hz. That’s why 136 is selected.

When fundamental frequency of a note is lower than 8.18 Hz, some overtones on high frequency may lost. However, cubic interpolation may cause noise which makes those frequency not to be 0.

    noteToFreq(note) := 440 * Math.pow(2, (note - 69) / 12)
    noteToFreq(0) = 8.175798915643707
    noteToFreq(136) = 21096.16364242367
    noteToFreq(137) = 22350.606811712252

Wavetable is represented as 2D array with size of `136 * 2^18`. Bicubic interpolation is used to get the value from the table. Coordinate on time/band-limit axis is determined by phase and frequency of oscillator.

The size of wavetable is large for a synthesizer. Xrun may occur if memory is slow. It may also consume more resources for higher notes because access pattern becomes close to random.

## PADsynth Algorithm Overview

CubicPadSynth uses PADsynth algorithm, which is originated from ZynAddSubFX. Yoshimi is also using PADsynth algorithm.

Passing phase randomized spectrum to IDFT (inverse discrete fourier transform) generates a cyclic waveform which is smooth when connecting an end to another end. PADsynth is utilizing this property.

“Profile” function is used to synthesize spectrum. CubicPadSynth uses normal distribution curve for profile, which is same as original PADsynth algorithm. Center frequency of profile can be set arbitrary. In default, CubicPadSynth uses fundamental frequency set by `Base Freq.` and its overtones.

## Block Diagram

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.

## Parameters

### Main Tab

#### Tuning

Octave, Semi, Milli

  Changes master pitch.

  `Milli` is 1/1000 of semitone or 1/10 cent.

ET, A4 [Hz]

  Changes tuning.

  `ET` stands for equal temperament. Note that when `ET` is less than 12, some notes becomes silent due to frequency becomes too high or too low.

  `A4 [Hz]` is frequency of note A4.

#### Gain

A, D, S, R

  Gain envelope parameters.

  - `A` : Attack time which is the length from note-on to reaching peak value.
  - `D` : Decay time which is the length from peak value to reaching sustain level.
  - `S` : Sustain level which is the gain after decay.
  - `R` : Release time which is the length from note-off to the gain reaching to 0.
Gain

  Master output gain.

#### Lowpass

This is a psuedo low-pass filter. It shifts to wavetable which contains less overtone to get low-passed output.

Equation to get cutoff frequency is following.

    cut = Cutoff * 128
    keyFollowRange = Cutoff * (nTable - pitch)
    lowpassPitch = (cut + KeyFollow * (keyFollowRange - cut)) - lowpassEnvelope * Amount;
    if (lowpassPitch < 0) lowpassPitch = 0

    noteToFreq(note) := 440 * Math.pow(2, (note - 69) / 12)
    range  = noteToFreq(nTable)
    lpFreq = noteToFreq(midiNote + lowpassPitch)
    ntFreq = noteToFreq(midiNote)
    cutoffFrequency = (1 + (range - lpFreq) / range) * ntFreq

128 used to calculate `lpCut` is an arbitrary value which came from MIDI note number range + 1. `nTable` is set to 136.

Cutoff

  Changes filter cutoff frequency.

KeyFollow

  When set to right-most, cutoff frequency is set to make the number of overtone to be almost same regardless of pitch of note. When set to left-most, it only use the value of `Cutoff`.

A, D, S, R, Amount

  Filter envelope parameters. `Amount` changes the amount of modulation to cutoff.

#### Pitch

A, D, S, R, Amount

  Pitch envelope parameters.

Negative

  Changes the sign of pitch envelope output.

#### Unison

nUnison

  Number of voices used by unison.

  To avoid interruption of release, increase the number of `nVoice` in Misc. section. Note that increasing `nVoice` consumes more resources.

Detune, Random Detune

  `Detune` is the difference of pitch between voices used in a unison.

  When `Random Detune` is checked, amount of detune changes for each note-on.

      random = RandomDetune ? rand() : 1
      detune = pitch * (1 + random * unisonIndex * Detune)

GainRnd

  Amount of randomization of gain for voices used in a unison.

Phase

  Amount of randomization of phase for voices used in a unison.

  This parameter makes no effect when `Reset` in Phase section is checked.

Spread, Spread Type

  `Spread` is an amount of stereo spread for a unison.

  `Spread Type` provides options to assign panpot values according to voice pitch.

  - `Alternate L-R`: Alternates `Ascend L -> R` and `Ascend R -> L`.
  - `Alternate M-S`: Alternates `HighOnMid` and `HighOnSide`.
  - `Ascend L -> R`: Ascend pitch from left to right.
  - `Ascend R -> L`: Ascend pitch from right to left.
  - `HighOnMid`: Ascend pitch from side to mid.
  - `HighOnSide`: Ascend pitch from mid to side.
  - `Random`: Randomize pan. May be biased.
  - `RotateL`: Rotate to left for each note-on.
  - `RotateR`: Rotate to right for each note-on.
  - `Shuffle`: Randomly assign pan which is evenly ordered.

#### LFO

Refresh LFO

  Refresh LFO wavetable based on current value of `LFO Wave`.

  Note that refreshing wavetable stops sound. It also interrupts MIDI notes.

Interpolation

  Type of LFO wavetable interpolation.

Tempo, Multiply

  Sets LFO frequency according to current tempo. Lower numeral represents the length of note. Upper numeral is the number of notes.

  Value of `Multiply` is multiplied to the frequency calculated from `Tempo`.

      // (60 seconds) * (4 beat) = 240
      lfoFrequency = Multiply * (BPM / 240) / (TempoUpperNumeral / TempoLowerNumeral)

Retrigger

  When checked, resets LFO phase for each note-on.

Amount

  LFO frequency modulation amount.

Lowpass

  Changes cutoff freequency of low-pass filter for LFO.

LFO Wave

  LFO waveform.

#### Phase

Phase

  Initial phase of oscillator.

Reset

  When checked, resets oscillator phase to the value set by `Phase`.

Random

  When checked, randomize phase for each note-on. In this case, value of `Phase` becomes range of randomization.

#### Misc.

Smooth

  Time length to change some parameter value to current one. Unit is in second.

  List of parameters related to `Smooth`. `*` represents wild card.

  - All parameters in Tuning section.
  - Gain

  Gain of profile.

Width

  Width of profile.

Pitch

  This value is multiplied to profile center frequency.

Phase

  Range of randomization for the phase of profile.

#### Pitch

      profileCenterFrequency = mod(
        BaseFreq * profileIndex * overtonePitch * Multiply,
        440 * pow(2, (Modulo - 69) / 12)
      )

Random

#### Spectrum

Expand

  Scaling factor to shrink/expand the spectrum along to frequency axis.

Shift

  Shift spectrum along to frequency axis.

Comb

  When this value is higher than 1, it changes the shape of profile like a comb. The value specifies interval between peaks.

Shape

  Changes profile shapes by using the value of `Shape` as an exponent.

      shapedProfile = powf(profile, shape);

Invert

  Invert spectrum to make the maximum of absolute value to 0, and 0 to the max-abs value. Signs are preserved. Phases aren’t considered.

      maxRe = max(abs(spectrumRe))
      maxIm = max(abs(spectrumIm))
      invertedSpectrumRe = spectrumRe - sgn(spectrumRe) * maxRe
      invertedSpectrumIm = spectrumIm - sgn(spectrumIm) * maxIm

#### Phase

UniformPhase

  When checked, phase of a profile becomes an uniform value.

#### Random
