Free Online Synthesizer – Fluoresynth

How does Fluoresynth work?
The Fluoresynth synthesizer uses the harmonic series to create pitched musical tones. This series also determines the sounds of string, brass, and woodwind instruments.
Unlike traditional instruments, you can customize Fluoresynth’s harmonics as you play it.
Fluoresynth’s harmonic series consists of a fundamental tone and 12 overtones. The relationship between the fundamental and its overtones determines the sound’s brightness and warmth.
Mellow or Bright Timbre
Fluoresynth sounds mellower when the overtones are much quieter than the fundamental frequency.
