The Resurrection of Eurorack’s Most Sophisticated Rhythm Brain
In the fast-moving world of modular synthesis, products come and go with startling frequency. But when WMD announced the return of their legendary Metron 16-channel trigger sequencer, it felt less like a product announcement and more like the resurrection of a fallen king. This isn’t just another sequencer returning to production—it’s the restoration of what many consider the most advanced trigger sequencing ecosystem ever created for Eurorack.
The Metron’s return, complete with updated firmware v1.6 and renewed commitment to the entire sequencing ecosystem, represents more than nostalgia. It’s recognition that some tools are too powerful, too essential, to remain buried in the discontinued archives.
Philosophy Meets Precision: The Metron Ecosystem Vision
WMD didn’t just create a sequencer with the original Metron—they envisioned an entire ecosystem where the core module could expand through dedicated companions like the Voltera and Axxent. This modular approach to sequencing mirrors the modular synthesis philosophy itself, allowing users to build exactly the performance interface they need.
The ecosystem approach distinguishes the Metron from single-module solutions. Rather than cramming every possible feature into one overwhelming interface, WMD distributed functionality across specialized modules that work in perfect harmony. The result is a sequencing system that scales from simple pattern creation to complex live performance setups.
Sixteen Channels of Rhythmic Authority
At its core, the Metron delivers 16 independent channels of trigger and gate signals—enough to drive a substantial modular drum setup or trigger complex polyrhythmic patterns across multiple modules. But raw channel count only tells part of the story; it’s the Metron’s sophisticated approach to pattern management that sets it apart.
Core Sequencing Features:
- 16 independent trigger/gate channels
- Up to 256 steps per pattern
- Different pattern lengths per channel for polyrhythmic complexity
- Five instantly recallable, editable variations
- Real-time variation editing without stopping playback
- FX/Fills for momentary pattern variations
- Probability per step and group probability functions
The ability to edit variations while others play removes one of live electronic music’s biggest constraints—the need to stop the music to make changes. This feature alone transforms the Metron from a studio tool into a genuine performance instrument.
Interface Intelligence: Four-Channel Focus with Single-Track Zoom
The Metron’s interface design reflects deep understanding of how musicians actually work with complex sequencers. Rather than overwhelming users with all 16 channels simultaneously, it displays four channels at a time with easy switching between views. This focused approach reduces cognitive load while maintaining access to the full pattern complexity.
The single-track view mode provides even more detail, showing 64 steps of a single channel for precise editing of longer patterns. This zoom functionality bridges the gap between pattern overview and step-by-step precision, accommodating both compositional and performance needs.
Advanced Pattern Features: Beyond Basic Triggering
Where many trigger sequencers stop at simple on/off functionality, the Metron extends into sophisticated pattern manipulation territory:
Burst Per Step: Creates ratcheting and roll effects by triggering multiple events within a single step, perfect for creating the kind of rhythmic complexity that defines modern electronic music.
Step Looping: Allows sections of patterns to repeat while others continue, creating dynamic rhythmic relationships that evolve over time.
Custom Fill Patterns: Provides instant access to alternative pattern sections, essential for live performance and arrangement building.
Random Pattern Generation: Offers algorithmic assistance for breaking out of familiar rhythmic patterns, generating new ideas and unexpected combinations.
These features transform the Metron from a simple trigger source into a creative partner that can surprise and inspire during the composition process.
Expandability: The Voltera and Axxent Advantage
The true power of the Metron ecosystem emerges when expanded with its dedicated companions. The Voltera adds additional gate outputs and hands-on control, while the Axxent provides voltage lanes for parameter control, pitch sequencing, and complex modulation scenarios.
This expandability means the Metron can grow with your system and performance needs. Start with the core module for basic trigger sequencing, then add expansions as your requirements become more complex. It’s an investment approach that protects against obsolescence while providing clear upgrade paths.
Performance Integration: Built for Live Use
The Metron’s design prioritizes live performance through features that many studio-focused sequencers overlook:
Non-Stop Pattern Loading: Patterns can be loaded from SD memory without stopping playback, essential for seamless live sets.
Variation Previews: View patterns before loading them, preventing the sonic disasters that can derail live performances.
External CV Control: Two assignable inputs allow external modules to influence sequencer behavior, creating dynamic performance setups.
Tap Input with Quantization: Real-time pattern entry with automatic quantization maintains timing precision while enabling spontaneous creativity.
MIDI Integration: Beyond the Modular Realm
The MIDI Preset mode extends the Metron’s influence beyond pure trigger sequencing. By sending MIDI messages over the Doepfer CV bus, it can control other modules like the WMD SSM and Malekko Voltage Block, creating complex automation scenarios that span multiple modules.
This integration capability transforms the Metron from a drum sequencer into a central nervous system for modular performances, coordinating not just rhythmic elements but entire sonic environments.
Firmware v1.6: Evolution Through Software
The return of the Metron brings updated firmware v1.6, available to both new and existing users. This commitment to ongoing software development demonstrates WMD’s serious approach to product lifecycle management—recognition that sophisticated sequencers improve through iterative refinement rather than replacement.
The availability of firmware updates to existing users shows respect for the Metron community that kept the demand alive during its absence. It’s the kind of manufacturer support that builds lasting relationships rather than just driving new sales.
Internal Clock with Character
While external clocking is essential for modular integration, the Metron’s internal clock provides more than just convenience. The inclusion of swing functionality adds rhythmic character that can transform rigid patterns into grooving sequences, bringing human feel to precise digital timing.
This attention to rhythmic character distinguishes the Metron from purely functional trigger sources, acknowledging that timing isn’t just about precision—it’s about musical expression.
SD Memory: Patterns for Life
The SD card storage system ensures that patterns survive power cycles and can be easily backed up, shared, and organized. In an ecosystem where losing a perfect pattern can feel devastating, reliable storage becomes a creative enabler rather than just a technical necessity.
The ability to organize patterns externally also supports the kind of preparation that live performance demands, allowing sets to be planned and arranged with confidence.
Investment in Excellence: $749 for Sequencing Supremacy
At $749, the Metron represents a significant investment, but one that reflects the sophistication and expandability of the complete system. This isn’t an impulse purchase—it’s a long-term commitment to a sequencing approach that can anchor modular systems for years.
The pre-order availability suggests WMD is serious about meeting demand while maintaining production quality. Given the Metron’s previous reputation and the improvements in firmware v1.6, early adoption seems less risky than usual.
The Return of the King
The Metron’s resurrection represents more than product availability—it’s validation that some tools are too essential to remain discontinued. In an era of simplified sequencers and software solutions, the Metron’s complexity and hands-on approach feel increasingly valuable.
Whether you’re building a performance-focused modular system, need sophisticated trigger control for complex drum setups, or want to explore the boundaries of rhythmic possibility, the Metron offers capabilities that simply don’t exist elsewhere in the Eurorack ecosystem.
