Inharmonic

A shiny synthesizer like a piano.

The Inharmonic simulates the overtone characteristics of acoustic pianos. It's possible to synthesize more natural (physics-oriented) inharmonic sounds that FM synthesis could not.

• 2 Additive Synthesis Oscillators (polyphonic)
• 1 State Variable Filter (LPF12, HPF12, BPF12, LPF24, HPF24, BPF24)
• 1 Chorus
• 1 Bitcrusher
• 1 Reverb

Notes (for Geeks)

The Inharmonic uses sinusoidal additive synthesis to generate overtones. According to H. Fletcher (1964), the $n$-th overtone frequencies $f_n ~(n=1, 2, \dots)$ can be modeled as

$$ f_n = n f_0 \sqrt{1 + Bn^2} \approx n f_0 (1 + B n^2 / 2) $$

, where $B$ is inharmonicity.
