FX Tab - HALion - 7.1

Allows you to adjust the spectral purity of the sound. A setting of 0% corresponds to the original sound.

• Positive values increase the level differences between partials, which results in a pure sound.

• Negative values decrease the level differences between partials, which results in a noisy, impure sound.

This parameter scales the frequency offsets of all partials. The effect of this parameter largely depends on whether frequency offsets exist in the signal. If a sound is strictly harmonic, that is, if there are no frequency offsets, the Inharmonicity control does not have an effect.

The frequencies of the partials are compared to the harmonic series, starting two octaves below the played pitch. If a sound is not strictly harmonic, the frequencies of some of the partials are offset to match the frequencies of the assumed harmonic series.

At 0%, only harmonic frequencies are allowed. A setting of +100% corresponds to the original sound. At +200%, the frequencies are assigned twice the frequency offset. Negative values invert the frequency offsets accordingly.

The Blur effect smears the incoming signal with regard to its time and frequency, which creates effects similar to chorus or reverb, but with a very unique sound character. For example, in conjunction with Speed settings below 10% on the Osc page, this effect can be used to create an atmospheric “wall of sound”.

• Blur On/Off activates/deactivates the effect.

  Changing this setting only takes effect with the next note-on that is received.

• Blur Time determines the amount of time smearing. In the course of the specified time, the incoming spectrum decays by 60 dB. This creates a characteristic smearing effect over time.

• Blur Depth determines the amount of frequency smearing. Each frequency in the spectrum is randomized. The effect ranges from subtle chorusing (<10%) to random pitch modulation (>10%).

• Blur Mix determines the mix between the original spectrum (dry) and the blurred spectrum (wet). It works like a dry/wet mix parameter of a chorus or reverb effect, for example. The blue curve in the frequency spectrum indicates the dry signal, the purple curve indicates the effect signal.

• If Direct Blur is deactivated, the attack time increases with the Blur Time, which means that, the longer you set the Blur Time, the more slowly the sound fades in. If you want the sound to start directly, activate Direct Blur.
