The Polyphonic FM Synth is a digital instrument designed for creating rich, expressive tones using frequency modulation synthesis with full polyphonic capabilities.

It features two separate ADSR (Attack, Decay, Sustain, Release) envelope controls—one for the amplitude and another for the modulator—allowing for the intricate shaping of both volume and tone over time. The Ratio knob adjusts the frequency relationship between the carrier and modulator, a key parameter for crafting harmonically rich or metallic sounds.

The Brightness control modifies the timbral sharpness, influencing how intense or mellow the modulation sounds. A final Gain slider ensures your output level is clean and controlled, with visual feedback in decibels.

Compact and intuitive, this synth offers creative flexibility for sound designers and musicians looking to explore the powerful and digital world of FM synthesis with polyphony.
