The E-mu Planet Earth is a sound module released in 2000 that carved out a unique niche for itself by focusing exclusively on the sounds of the world . While its collection of ethnic instruments is impressive, it's the module's approach to percussion that makes it a truly special piece of gear. Here is a review with a specific focus on its percussive capabilities.
A Rhythmic Powerhouse: The Percussion Review of the E-mu Planet Earth
If you are a composer, producer, or sound designer looking to add authentic, organic rhythm to your music, the E-mu Planet Earth is a module you owe it to yourself to explore. This 1U rack unit is a treasure trove of global sound, but where it truly shines—and what keeps it relevant decades after its release—is its incredible depth and flexibility with percussion .
The Heartbeat: An "Uncountable" Collection of Sounds
The Planet Earth's core is a 32 MB ROM packed with high-quality, 16-bit samples recorded from all corners of the globe . For percussion enthusiasts, this is paradise. The module delivers an "uncountable" number of individual drum sounds and fully assembled kits . You're not just getting a generic "djembe" or "talking drum"; you're getting a carefully multi-sampled instrument that responds to velocity, offering the subtle timbral changes that make percussion come alive.
The sound list reads like a musician's journey around the planet :
- Africa: Djembe, talking drum, shékere, balafon, and the gankokwe (a Nigerian gong).
- Brazil: The full spectrum of samba percussion, including surdo (with velocity-sensitive samples for different intensities), agogo, tambourim, cuíca, and pandeiro.
- The Middle East & Asia: Frame drums, darabuka, and even specific steel drum samples mapped across the keyboard to replicate the range of a real pan .
This is far beyond the simple "world music" multi-samples found in general-purpose romplers. The Planet Earth is a dedicated archive of global rhythm.
The Secret Weapon: SuperBEATS Mode
What truly elevates the Planet Earth from a simple sound module into a rhythmic powerhouse is the SuperBEATS Mode . This feature allows you to trigger, latch, and manipulate synced loops and grooves directly from your keyboard . Instead of just playing a static conga sound, SuperBEATS lets you trigger a complex, authentic conga pattern that stays perfectly in time with your sequencer or arpeggiator.
This is a game-changer for sketch ideas and live performance. You can build intricate, polyrhythmic arrangements on the fly, layering a djembe loop over a surdo pattern with a few key presses. It transforms the module from a passive sound source into an interactive drum machine, putting the power of a world percussion ensemble at your fingertips .
Shaping the Groove: Synthesis and Arpeggiation
The raw samples are just the beginning. The Planet Earth is built on E-mu's powerful 4-layer synthesis architecture, which means you can warp and sculpt those pristine percussion hits . You can route sounds through the famous E-mu Z-Plane filters, offering everything from classic low-pass filtering to resonant band-pass and even complex formant filters that can make a simple drum sound completely alien and new .
On top of that, the module features up to 16 syncable arpeggiators . You can assign different percussion sounds to different arpeggiators, creating complex, evolving rhythmic sequences that would be tedious to program by hand. This combination of authentic samples, deep synthesis, and powerful rhythmic tools allows you to create everything from pristine, traditional sounds to heavily processed, modern, hybrid textures.
A Few Considerations
It's important to remember what the Planet Earth is and is not. As one user put it, it is a "purely ethnic module," so you won't find "meat and potato" sounds like analog basses or standard rock drum kits . While it has some pads and synth textures built from its world samples, its primary focus is firmly on global instruments . Its strength is also its limitation.
Furthermore, the module is a product of its time. While the sounds are clear and colorful, some users note that the overall audio quality might not have the same "warmth" as some competitors from the era, like the Roland JV line with its World expansion card . However, for many, the sheer breadth and authenticity of the percussion library more than compensates.
The Verdict
The E-mu Planet Earth is a cult classic for a reason. For those focused on rhythm and percussion, it is arguably one of the best sound modules ever made. The combination of its vast, authentic sample library and the innovative SuperBEATS mode creates an instrument that is both a deep sound source and a performance tool . One owner perfectly captured the sentiment, stating, "I have mine and I will never sell it" . If you find one on the used market and your music craves the pulse of the planet, do not hesitate.
