The bx_subsynth Subharmonic Synth plug-in by Brainworx is inspired by the classic dbx 120XP Subharmonic Synthesizer, designed to enhance low-end frequencies with powerful subharmonic synthesis. It allows producers and sound designers to add deep, punchy bass without compromising the clarity of midrange elements. This makes it ideal for beefing up kick drums, bass synths, and even vintage vinyl recordings, delivering the thick and impactful low-end that defines many dance and electronic music styles.

Building upon the original's Waveform Modeling engine, the bx_subsynth introduces a third synthesis band that extends the frequency range up to 80 Hz. This enhancement expands the plug-in’s capability to process a broader spectrum of sounds, capturing essential instrument fundamentals and adding depth to a variety of sources. The Edge section offers additional control by enabling compression and saturation, which helps shape subharmonic content or create dynamic, explosive peaks for an engaging low-frequency presence.

Full stereo spectrum control is provided through advanced M/S processing, allowing users to isolate and enhance the mid channel without affecting the sides. Features like Mono Maker and Stereo Width ensure the low-end remains in phase and balanced within the stereo field, offering precise control over the spatial characteristics of the bass. This combination of detailed subharmonic synthesis and stereo manipulation makes the bx_subsynth an essential tool for crafting powerful, well-defined basslines in modern music production.
