FM KOSMOS

Imagine packing the punch of six FM operators per voice into a tidy 22 HP Eurorack module that handles everything from synthesis to effects—no cable spaghetti required. Released in 2024, this 4-voice polyphonic beast draws inspiration from classic FM ratios like those in the DX100, but streamlines it all for modern modular rigs.

At its heart, you'll find 32 selectable algorithms, loopable ADSR envelopes on each of the six operators, plus ratio and level tweaks for precise sound sculpting. Eight dedicated knobs smartly remap to the active page—whether editing an operator, morphing between A and B sound variants, or dialing in the built-in multi-effects like stereo chorus, MIDI-syncable delay, and reverb. A graphical display keeps things clear, with CV inputs for 1V/oct, gate, velocity, morph, and two user-assignables, alongside TRS MIDI in/out and stereo audio out at modular levels. It fits snug at 30mm deep, sipping just 120mA on +12V.

Early adopters love how the morph function breathes life into static FM patches, turning bells into evolving pads effortlessly, though some note the menu diving for deeper edits could feel more immediate. With 128 factory presets and 128 user slots, it's a creative shortcut that slots perfectly into Flame's lineup of compact powerhouses.
