ALM / Busy Circuits is a UK-based modular synth manufacturer known for clean design, clever engineering, and modules that quietly become essentials in a Eurorack system. Founded by musician and engineer Matthew Allum, the brand has a reputation for solving real musical problems rather than chasing gimmicks, which is why their modules show up in so many serious, long-term racks.
The range covers everything from rock-solid clocking and sequencing to sampling, modulation, mixing, and performance utilities. ALM modules are typically compact, logically laid out, and designed to work beautifully with other brands as well as with each other. Whether you’re building a tight live performance system or a deep studio rack, ALM Busy Circuits gear is trusted for its reliability, musicality, and thoughtful approach to modular synthesis.
Digital is sound generation and processing based on digital signal processing rather than analogue circuitry. It is used for precise control, stable tuning, patch memory, and complex sound design that would be difficult to achieve with purely analogue systems. For example, a digital instrument might be used to create detailed evolving textures or realistic emulations while storing and recalling complete sound setups instantly.
Dual indicates that an instrument or module contains two identical or complementary sections. This can apply to oscillators, filters, envelopes, or channels, allowing parallel processing, stereo operation, or more complex sound design within a single unit.
A module is a self-contained unit designed to perform a specific function within a larger system. Modules are commonly used in modular and Eurorack setups, where each unit handles tasks such as sound generation, modulation, filtering, or control, allowing systems to be built and expanded piece by piece.
New Gear is unused and in original condition, supplied as it leaves the manufacturer. It is chosen for guaranteed reliability, full functionality, and the assurance of manufacturer support. For example, buying new ensures access to the latest design revisions, included accessories, and official warranty coverage.
