FM synthesis is powerful but often intimidating — traditionally packed with complex algorithms, obscure parameters, and a steep learning curve. Halogen FM was designed to change that. It removes the usual technical barriers, giving you immediate access to the rich, expressive world of FM without requiring deep synth programming knowledge.
Instead of overwhelming you with menus and math, Halogen invites you to explore sound through play. It’s a generative instrument that responds to instinct, not instruction — creating evolving textures, organic tones, and unexpected surprises. Whether you're a seasoned producer or just curious, Halogen FM makes the creative process feel natural, engaging, and fun.
At the heart of Halogen FM is the Spark Core — a powerful engine designed to generate musical, character-rich patches with a single click. Tap the global Spark button to instantly create a new sound. Then, refine it using high-level macro controls like Timbre, Envelope Generators (EGs) for OSC 1 and 2, Modulation, and FX. These macros let you explore subtle tonal shifts and entirely new directions — all without diving into deep parameter tweaking.
Halogen is built for immediacy and simplicity. But when you do want to dive deeper, each operator’s full set of parameters is fully accessible, giving you complete control without ever getting in the way of your flow.
Halogen FM makes sound creation feel immediate and rewarding, while offering surprising depth for those who want to go further. Start by clicking the global Spark button to instantly generate a brand-new patch.
Alternatively, you can click the Operator Spark button to randomise just one operator, or use the Spark buttons next to the macro knobs (Timbre, EGs, Mod, FX) to refresh specific aspects of the sound — giving you controlled variation without losing the core of what you like.
Then shape the sound further with intuitive macro controls:
This hands-on workflow gives you the best of both worlds: fast inspiration and nuanced expression — allowing you to sculpt unique, expressive FM sounds with ease and creativity.
Halogen FM’s architecture is inspired by a lesser-known Japanese FM synth, reimagined for modern sound design and creative spontaneity. At its core are two sonically distinct operators with identical control sets — each featuring Level, Pan, Pitch, Ratio, Frequency, Brightness, Distortion, and Timbre, along with extensive modulation options. These tools give you a sound engine that’s both highly expressive and deeply musical.
The design embraces imperfection and unpredictability, making it easy to discover new textures and timbres that feel alive and dynamic — whether you're shaping precise tones or chasing happy accidents.
