A Gritty Bass Sound

Part three of our Valentine's Day special!
Synth Recipe: Perfume's ‘Chocolate Disco’
This time we create the gritty bass sound that drives the song.
Reference Track

This bass has a slightly unusual, nasal tone.
We'll create it by combining a sub-bass, a pulse wave, a filter, and more.
How to Create the Sound
Applying the Filter

Apply a standard low-pass filter.

Use ENV 1 to add movement to the filter.
Adjust it so the tone changes slightly as soon as a note sounds.
Applying Effects
Apply effects to shape the sound further.

Use S Shaper to add distortion to the sound,
making it thicker and giving it its characteristic aggressive edge.

Use the filter to cut unwanted low and high frequencies.
The sound is now complete!
Frequently Asked Questions
Q1. What characterizes the bass sound in Perfume's ‘Chocolate Disco’?
It has a distinctive nasal tone, achieved by combining a pulse wave and sub-bass. A low-pass filter and S Shaper effect give the bass a thick, aggressive sound with plenty of presence.
