Title: Underground vs. Sonore: Which Toontrack EZX is Right for Your Next Production?

Meta Description: Digging into the Toontrack Underground EZX and the cinematic Sonore EZX. We break down the sounds, the vibe, and how to use these extensions in EZdrummer or Superior Drummer.


If you’ve spent any time in the Toontrack ecosystem, you know the hardest part isn’t programming drums—it’s choosing which sound to start with. Two expansions that often get mixed up (or pitted against each other) are the Underground EZX and the Sonore EZX.

One is raw, gritty, and built for alt-rock basements. The other is lush, cinematic, and feels like a film score.

Let’s clear up the confusion. Here’s everything you need to know about both, how they work as “extensions” (EZX), and which one belongs in your template.


Head-to-Head: Underground vs. Sonore

| Feature | Underground EZX | Sonore EZX | |---------|---------------------|----------------| | Recording Space | Basement / live room | Stone church | | Overall Tone | Dry, punchy, aggressive | Wet, airy, resonant | | Best Genre | Grunge, alt-rock, punk | Cinematic, folk, ambient | | Room Sound | Tight & boxy (in a good way) | Huge & cathedral-like | | Dynamic Range | Medium to loud | Whisper to medium | | MIDI Included | Rock, punk, shuffle | Ballad, brush, half-time |


Sound Design & Character

Marketing Angle & Tagline

1. The "Not-Sampled" Feel

Many drum VSTs suffer from "machine gun" effect—the same hit repeated sounds identical. The Underground EZX, especially when triggered via the "Sonore Full" mapping, includes over 16 velocity layers for the snare drum. The result? Ghost notes sound breathy; rim shots crack like a .22 rifle.

The Kits

The Cymbal Selection

For the "Sonore" fan, the cymbals are key. You won't find pristine Zildjian K Customs here. Instead, you get:

These imperfections allow the drums to sit in a mix without harsh EQ boosts—the tone is already carved out.


Toontrack Sonore EZX: Cinematic & Breathable

Best for: Film scoring, post-rock, singer-songwriter, ambient, and indie folk.
