𝐅𝐞𝐚𝐭𝐮𝐫𝐞𝐬

• Dub Engine: Deep, resonant chords with up to 5 voices per trigger, amplitude envelopes and organic velocity variation for analogue warmth.

• Global Delay: Feedback delay with high-feedback capabilities to darken repeats. Feedback depth and wet level are both adjustable.

• Global Reverb: Atmospheric reverb network for spatial depth.

• Phaser Modulation: Add swirling movement to the sound with the built-in phaser effect.

• WAV Recording: One-click recording to a WAV file named with a date-time stamp. Captured post-master volume for a clean, ready-to-use bounce.

• Multi-Language Keyboard Support: Interface and keyboard bindings adapt to English (QWERTY), French (AZERTY), Russian (ЙЦУКЕН), Japanese (JIS) and Korean (두벌식) layouts. On-screen key labels update to match the selected locale.

• Standalone: Runs as a native application on macOS (Sonoma, Sequoia, Tahoe) without a browser.

• Zero Dependencies at Runtime: No internet connection required. Fully self-contained once installed.

Parameter	Range	Description
Pitch	-24 to +24 st	Master semitone transpose applied to the entire engine.
Vel Rand	0 - 100%	Adds organic velocity variation to triggered chords for a more human feel.
Chance	0 - 100%	Probability of a chord triggering. Lower values create sparse, generative rhythms.
Cutoff	20 Hz - 20 kHz	Low-pass filter cutoff frequency. Sculpt the character of the dub chord.
Reso	0 - 100%	Filter resonance (Q). Higher values accentuate the cutoff frequency.
Phaser	0 - 100%	Phaser depth. Adds a swirling, sweeping movement to the sound.
Delay	0 - 100%	Delay wet level and feedback depth. Creates infinite space and rhythmic echoes.
Reverb	0 - 100%	Reverb wet level. Adds atmospheric depth and wash to the chords.

𝐁𝐚𝐬𝐞 𝐍𝐨𝐭𝐞 & 𝐕𝐨𝐢𝐜𝐢𝐧𝐠

The Base Note sets the root of the chord relative to each key pressed. The chord shape is always built upward from the played note. Combining Base Note with the Pitch transpose lets you voice chords in any key without remapping the keyboard.

The Voices control adjusts the density of the chord, allowing you to select between 3, 4, or 5 simultaneous notes per trigger.

French (AZERTY), Russian (ЙЦУКЕН), Japanese (JIS) and Korean (두벌식) layouts are available from Options > Language. Selecting a language remaps both the on-screen key labels and the computer keyboard bindings to match the physical layout of that locale.

Press the Rec button in the header to begin capturing audio. Press it again to stop. A .wav file is exported automatically and named using the application name and the current date and time (e.g. dubchords_2026-06-26_14-30.wav). Recording captures the full processed signal including delay and reverb.
