Color Configuration

Free Pitch Plugin

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.

Below is a example of style.json.

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.

• fontPath: Absolute path to *.ttf font file. Not implemented in VST 3 version.
• 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

Knob and slider can do:

• Ctrl + Left Click: Reset value.
• Shift + Left Drag: Fine adjustment.

There is an additional control for number sliders used for Octave, Seed etc.

• Middle Click : Flip minimum and maximum.

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.

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

128 wavetables are generated. The number 128 comes from MIDI note number range. The indices of wavetables correspond to MIDI note numbers.

When tuning is not exact, an index will be truncated to semitones. For example, if MIDI note number is 60 and tuning is -20 cents, index becomes floor(60 - 0.20) = 59. Thus, 59th wavetable will be used.

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

Gain

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.

Master output gain.

Lowpass

Naive 3-pole low-pass filter.

Cutoff frequency of the filter.

Resonance of the filter. Be careful when turning to right, output will be loud.

When set to right-most, cutoff frequency is set to the frequency of a note. When set to left-most, it only use the value of Cutoff.

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

Tuning

Changes master pitch.

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

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.

Unison

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

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

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

Lfo Plugin

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

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

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.

Phase

Initial phase of oscillator.

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

Pitch Changer Vst

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