Chorus

Introduction to Multiply

Multiply is a versatile chorus effect with a unique twist. Each simulated voice is processed with a phase randomizing filter so that unpleasant comb filter effects are omitted. The effect can be used to simulate the effect of several performers playing the same tones simultaneously, to widen the spatial image or to create special effects for sound design. Multiply can simulate up to 6 additional voices and both the pitch and the loudness of the voices can be modulated. There is also an integrated equalizer consisting of a low cut, low shelf, mid bell, high shelf and high cut filters that can be applied to the effect signal. An integrated pre-delay section makes it possible to create modulated and diffuse echo effects.

The graphical user interface of Multiply is designed to give quick and intuitive access to all the parameter settings defining the sonic quality of the effect.

User Interface

Parameter Settings

• Dry level (dB)

The amount of dry (unprocessed) signal to send to the output specified in decibel. You can use the toggle button to exclude the dry signal completely. You can lock the relation between the dry and effect levels by clicking the lock button between the dry and effect level sliders.

• Effect level (dB)

The amount of processed signal to send to the output specified in decibel. You can use the toggle button to exclude the effect signal completely.

• Frequency modulation rate (Hz)

The frequency modulation rate controls how rapid the tone fluctuations in the simulated voices should be. It is specified in Hertz.

• Frequency modulation depth (%)

The frequency modulation depth controls the amount of tone fluctuations in the simulated voices. It is specified in percent, ranging from no modulation (0%) to full modulation (100%).

• Amplitude modulation rate (Hz)

The amplitude modulation rate controls how rapid the loudness variations in the simulated voices should be. It is specified in Hertz.

• Amplitude modulation depth (%)

The amplitude modulation depth controls the amount of loudness variations in the simulated voices. It is specified in percent, ranging from no modulation (0%) to full modulation (100%).

• Voice count (#)

The amount of simulated voices.

• Stereo spread (%)

You can use the stereo spread parameter to control the stereo width of the effect signal. If the stereo spread is set to 0%, the effect signal will be mono when the input signal is mono and at 100% the full stereo width is achieved.

• Pre-delay (ms)

The pre-delay slider allows you to adjust the time is milliseconds before the effect signal arrives.

• Equalizer

You can use the output equalizer to apply filtering to the effect signal. The equalizer consists of high and low pass filters, a mid band bell, as well as high and low shelving filters. You can use handles to change the filter settings and the frequency in Hertz as well as the gain in dB are displayed as cursor information while making adjustments.

The filters in the equalizer have variable filter slopes. You can modify the filter slope by clicking the filter section you want to edit. A small arrow appears in the same color as the filter section. You can move this arrow using the mouse to modify the slope. In the below image, the green low shelf is selected, and it's slope handle is just to its right:

Use the ON button in the bottom left of the Equalizer to quickly enable or disable all filter bands. To the right of the ON button, you can toggle the different filters on or off.
