Factors to Consider When Choosing a Modular Synth

When I’m helping musicians choose their first modular synth, or expand an existing setup, I’ve found that five key factors consistently determine whether they’ll love their investment or regret it six months later. Power requirements often get overlooked until you’re staring at a beautiful module that your case simply can’t support, while rack space planning becomes essential as your collection inevitably grows beyond what you initially imagined. Your sound design goals, budget constraints, and how well the system integrates with your existing gear will ultimately shape every purchasing decision you make.

Power Requirements and Consumption

Although I’ve assembled countless modular setups over the years, I’ll admit that power considerations still catch me off guard sometimes—nothing quite compares to the frustration of connecting that perfect module only to discover your power supply can’t handle the additional load. Most modules require 12V power, though you’ll encounter some needing 5V or 15V, so compatibility with your case becomes essential. Power consumption varies dramatically, from efficient modules drawing 20mA to power-hungry processors exceeding 200mA. I always calculate my total power budget before expanding, accounting for those LED-packed sequencers and touchscreen modules that consume considerably more juice. Don’t forget additional effects units either—they’ll impact your overall consumption and could push you beyond your supply’s maximum ratings.

Rack Space Planning

The puzzle of rack space planning resembles arranging furniture in a studio apartment—every square inch matters, and poor decisions become glaringly obvious once you’re living with them daily. I calculate HP (horizontal pitch) requirements meticulously, ensuring my case accommodates current modules while leaving breathing room for expansion. Power consumption becomes critical here, as cramming modules into insufficient cases leads to unstable voltages and disappointing performance. I group modules by functionality—oscillators near filters, sequencers adjacent to utilities—creating logical signal paths that minimize cable spaghetti. Patch cable accessibility matters more than I initially realized; tightly packed modules create frustrating bottlenecks during creative sessions. I’ve learned to allocate 20-30% extra space for future acquisitions, because module acquisition syndrome strikes everyone eventually.

Sound Design Goals

Before diving into specific modules, I establish clear sound design objectives that’ll shape every subsequent purchasing decision, because wandering into modular synthesis without sonic goals practically guarantees expensive confusion and buyer’s remorse.

I determine whether I’m pursuing rich ambient pads, punchy basslines, or experimental textures, since each direction requires fundamentally different module combinations and synthesis approaches. Polyphony requirements greatly influence my choices—complex harmonic layers demand polyphonic modules, while aggressive lead sounds work perfectly with monophonic setups.

I prioritize modules offering diverse synthesis methods like granular, subtractive, or FM capabilities, expanding my sonic palette beyond basic oscillator-filter combinations. Essential modulation sources, including LFOs and envelopes, become non-negotiable for creating dynamic movement and evolving textures.

Finally, I evaluate patch points and connectivity options, ensuring seamless integration with existing gear while maintaining routing flexibility for future expansions.

Budget and Expansion

Every modular synthesizer purchase demands careful financial planning upfront, since what appears affordable initially can quickly escalate into thousands of dollars once you factor in essential accessories, expansion modules, and the inevitable case upgrades that accompany a growing system. I recommend starting with semi-modular synthesizers, which offer immediate functionality while providing expansion pathways that won’t require rebuilding your entire setup from scratch. Individual modules typically cost between $100 and $500 each, and you’ll need patch cables, power supplies, and cases that greatly impact your total investment. I’ve learned to budget for ongoing maintenance and upgrades, as the modular ecosystem constantly evolves with new technologies that’ll tempt you toward continuous expansion.

Connectivity and Integration

Since modular synthesizers thrive on interconnectivity, I’ve found that choosing modules with robust connectivity options determines whether your system becomes a cohesive instrument or a collection of isolated sound generators. I always prioritize CV/GATE/SYNC I/O capabilities because they’re essential for seamless integration with other modular gear and CV-compatible devices, creating dynamic modulation networks that breathe life into static sounds. MIDI connectivity through USB-C or TRS connections has become increasingly important in my studio workflow, allowing effortless communication with DAWs and other MIDI instruments for synchronized performances and recordings. Audio input/output features greatly expand sound design possibilities by routing external signals for processing, while ensuring Eurorack compatibility regarding dimensions and power requirements prevents costly integration headaches that I’ve learned to avoid through experience.

Learning Curve Complexity

When I first dove into modular synthesis, I quickly realized that the creative freedom comes with a learning curve that can feel overwhelming, especially if you’re shifting from traditional keyboards or software synthesizers. The manual patching process demands understanding signal flow between oscillators, filters, and envelope generators, terminology that varies greatly across different manufacturers. I’ll admit, those first sessions involved more confused cable-swapping than actual music-making, as the limitless customization options can paralyze decision-making rather than inspire creativity. However, I’ve found that online communities, tutorial videos, and dedicated forums become invaluable resources for maneuvering through these initial hurdles, transforming what initially feels intimidating into an engaging exploration of synthesis fundamentals and modular relationships.

On a final note

I’ve tested dozens of modular synths over the years, and these eight units represent the sweet spot between functionality, affordability, and creative potential. Whether you’re drawn to the Behringer 2600’s vintage warmth, the MicroFreak’s hybrid engine, or the Nanobox’s granular capabilities, each offers distinct sonic territories worth exploring. Start with your budget, consider your space constraints, then let your ears guide the final decision.
