FM synthesis is notoriously difficult to program — complex, technical, and often unintuitive. Halogen FM changes that. We built it to remove the barriers that have kept so many from exploring the raw, expressive power of FM.

Instead of diving into confusing algorithms or endless parameters, Halogen invites you to discover sound through play. It’s a generative instrument that responds to instinct, not instruction — giving you evolving textures, organic tones, and sonic surprises without requiring deep synth knowledge.

Halogen FM lets everyone tap into the beauty and unpredictability of FM synthesis — whether you’re a seasoned producer or just curious. Your ears lead the way, and happy accidents are part of the design.

The Halogen Spark Core
At the heart of Halogen FM is the Halogen Spark core — a powerful engine that generates unique, musical sounds full of character and spontaneity. Just hit the global Spark button and a brand-new patch comes to life instantly. Refining your discovery is easy,  simply tweak the Timbre, Envelope Generators for OSC 1 and 2, Modulation, and FX macro knobs to explore subtle shifts and surprising variations.

Halogen is designed to be intuitive — no programming required. But we also know that sometimes, you want to go deeper. That’s why each operator’s parameters are fully accessible, giving you detailed control when you need it — without ever standing in your way when you don’t.

Instant Inspiration, Infinite Depth
With Halogen FM, crafting unique sounds is lightning-fast, yet the depth of character might surprise you. Start by hitting the global Spark button to explore new patches instantly. Then, shape the sound further: turn the Timbre knob left for a softer tone or right for a bolder, more aggressive feel. Likewise, the Modulation knob dials in dynamic unpredictability to the right or a more refined tone to the left. For a smooth pad, turn the EG controls to the right; for a more percussive, plucking sound, turn them to the left.
This intuitive approach makes Halogen FM an instrument of both discovery and control, allowing you to sculpt sounds effortlessly and creatively.
