F2FM is a frequency modulation synthesizer crafted to deliver rich and dynamic bass sounds. Its unique architecture places a filter before the modulator, allowing for distinctive tonal shaping that sets it apart from traditional FM synths. This design enhances the modulation process, resulting in innovative sound textures that work well in various musical genres.

The synth offers 23 waveform options to choose from, giving users a broad palette for sound creation. It features two operator oscillators, each equipped with individual filters, which can be blended before reaching the modulator oscillator. This setup provides extensive control over the harmonic content and tonal complexity of the generated sounds.

Additional features include individual detuning capabilities for all three oscillators, supporting both frequency modulation (FM) and phase modulation (PM) modes. A comb filter is integrated to add distortion effects, further expanding the sonic possibilities. These elements combine to make F2FM a powerful tool for crafting unique bass timbres and exploring creative modulation techniques.
