Brand
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.

VCA is a voltage-controlled amplifier used to control the level and dynamics of a sound using control signals. It is used to shape volume over time, apply envelopes, and manage modulation depth within a system. For example, a VCA can be used to control how a note fades in and out or to regulate the strength of a modulation signal across a patch.
