Spherator FM is a frequency modulation synthesizer designed to deliver a wide array of sounds ranging from harmonic to inharmonic textures. It operates by using sine wave modulators to influence the frequency of sine wave carrier oscillators, generating rich and complex tones. This approach allows the creation of unique soundscapes, including spacey pads, dynamic synth leads, basses, keys, ambient textures, and atmospheric layers that suit various musical styles.

The synthesizer features four FM operators, each equipped with sine wave oscillators and dedicated ADSR envelope generators for precise control over the attack, decay, sustain, and release phases of the sound. Users can adjust pitch, octave, and note parameters to shape the tonal character, while the modulation matrix offers flexible routing between operators to craft intricate modulation patterns. This flexibility enables both subtle and dramatic sonic evolutions, making it suitable for a broad spectrum of creative applications.

Spherator FM also includes built-in effects such as stereo flanger, delay, and reverb, enhancing the spatial dimension and depth of the sounds. The flanger produces characteristic sweeping effects through phase shifting, while the delay adds echo and stereo width. The reverb contributes to creating atmospheric ambience with adjustable drive and limiting controls to manage tone and dynamics. Complemented by a preset manager with 40 diverse pre-programmed sounds, this synthesizer offers immediate inspiration alongside extensive customization options.
