Clean Subs & Partial Replacement (Patreon)

In this video, I show how you can use Bitwig Studio to manipulate bass overtones and create cleaner or more precise sub-basses.

I demonstrate how to add harmonics and even replace or double the fundamental with a pure sine wave using layering techniques and tools like the key track modulator, EQ Plus, and envelope followers.

I also cover methods for removing the fundamental and bringing back a static sub, whether you use Polymer, the wavetable oscillator, or other devices within Bitwig. These techniques let you shape and control every aspect of your bass sound, offering both creative flexibility and technical precision.

Simple method to add, double, or isolate harmonics using instrument layers and setting oscillator ratios

How to replace a bass fundamental with a clean sine wave for ultra-clean sub-bass tones

Using the wavetable oscillator’s “remove fundamental” feature and sub-oscillator for reconstructing clean sub-bass

Alternate technique: removing the fundamental with a steep EQ and reintroducing it via a separate synthesizer
