Feature highlights

• Huge collections of custom Xfer Serum presets tailored for modern bass music production. These include aggressive basses, gnarly reeses, growls, stabs, and impactful low-end tones. 
• Packs often contain 100+ to ~150+ presets spanning multiple bass types and lead textures, so producers have plenty of sound-design options. 
• Designed to serve bass-heavy genres like drum & bass, dubstep, halftime, UK bass, tearout, and bass house by offering sounds suited to different substyles.
• Presets are engineered for floor-shaking sub-bass, growling leads, and punchy mid-range hits to cut through mixes and energize drops. 
• Most presets are easily editable and modifiable within Serum — great for adding personal flair or tweaking characters to match your track goals
• Presets are set up to be used immediately in your projects and typically come royalty-free, meaning you can use them in commercial productions without extra fees.
