A cross-feedback FM synthesizer that creates sounds no other synth can make. Two oscillators, mutual feedback, chaos noise injection, and a full effects chain all designed for sound exploration.

Hear what Forma can do, from deep basses and expressive keys to soaring leads and lush pads.
Every detail designed for sound designers and producers who want something different.
Two oscillators feed back into each other simultaneously, not the one-way routing of traditional FM. Choose from sine, triangle, saw, or square waveforms for each oscillator and blend them with the Osc Mix control. Shape the interaction with Ratio, Feedback, Chaos, Tame, and Detune. The result is a huge range of timbres, from glassy bells to screaming leads, all from a single architecture.

An LFO with 5 shapes (sine, triangle, saw, square, sample & hold) can modulate nearly every parameter, each with its own independent speed multiplier. A full ADSR modulation envelope adds per-note movement to Ratio, Feedback, Chaos, Tone, Tame, and Detune.

Five distortion types (Tube, Tape, Fuzz, Bit Crush, Wavefold), a chorus with Hermite interpolation, a tempo-syncable delay, and an 8-line feedback delay network reverb. Each effect has its own mix and bypass. Shape your sound from raw oscillator to finished mix without leaving the plugin.

A built-in bank of over 120 presets across pads, basses, leads, keys, plucks, textures, and FX, all designed to showcase Forma's unique engine. Load a preset and start tweaking, or use them as a jumping-off point for your own sounds.
