Orinj Chorus

Not Rated Yet

Orinj version 3.0.0

The Orinj Chorus is meant to imitate and actual chorus – the same sound coming from multiple sources. The purpose of a chorus is to make the sound fuller. It does so, by repeating the signal multiple times (voices), with the same amplitude as the original signal (with no decay). To ensure that the sound is perceived as coming from multiple sources, each repetition is slightly offset in time from the original signal – it is delayed by a very small amount. To ensure that the effect imitates the natural occurrences of the chorus – a choir – the delay between the original signal and each repetition is not fixed, but varies slowly over time and by small amounts (the delay sweep).

Using the Orinj Chorus

The Orinj Chorus can be added to tracks in the multitrack session view, tracks in the loop building view and to waves in the single wave view. In the multitrack session view and in the loop building view, first select the track to which you want to add the effect. In all these views, click on Effect, Delay, and then on Orinj Chorus in the Orinj menu. You will see the following dialog.

The Orinj Chorus dialog

When this dialog becomes visible, the Orinj Chorus effect has been added. Adjust the parameters of the chorus – described below – in the dialog above and click Close.

Orinj Chorus parameters

See Orinj Effects for an explanation of the Title, Track, Presets, Bypass, and Lock channels controls. The remaining Orinj Chorus controls are described below:

  • Left channel voices: Use this control to set the number of voices in the left channel. The number of voices is the number of repetitions plus the original signal. The chorus can have between 2 and 100 voices (1 and 99 repetitions).
  • Left channel maximum delay: Use this control to set the maximum delay between the original signal and any of the repetitions in the left channel. The delay is specified in milliseconds (ms) and can be between 10 ms and 200 ms.
  • Left channel minimum delay: Use this control to set the minimum delay between the original signal and any of the repetitions in the left channel. This delay is specified in milliseconds (ms) and can be between 5 ms and 100 ms.
  • Left channel rate: Use this control to specify the rate at which the delay between the original signal and any of the repetitions in the left channel changes. The delay between the original signal and any of the repetitions is not constant, but changes (there is delay sweep). This parameter defines how quickly this happens. The rate is measured in milliseconds per second (ms/s) and can be between 0 ms / s and 50 ms / s. For example, a value of 5 ms/s means that the delay will change by at most 5 ms for every second.
  • Left channel invert: Click on this checkbox to invert the phase of the chorused signal in the left channel (to turn the signal upside down). Some chorus effects may be more interesting with this setting, depending on the settings for the remaining parameters.
  • Right channel voices: Use this control to set the number of voices in the right channel. This control works in the same way as the left channel voice control, but in the right channel.
  • Right channel maximum delay: Use this control to set the maximum delay between the original signal and any of the repetitions in the right channel. This control works the same way as the left channel maximum delay, but in the right channel.
  • Right channel minimum delay: Use this control to set the minimum delay between the original single and any of the repetitions in the right channel. This control works the same way as the left channel minimum delay, but in the right channel.
  • Right channel rate: Use this control to specify the rate at which the delay between the original signal and any of the repetitions in the right channel changes. This control works the same way as the left channel rate, but in the right channel.
  • Right channel invert: Click on this checkbox to invert the phase of the chorused signal in the right channel.
  • Left channel gain: Use these controls – the box and the slider – to set the gain that will be added to the left channel repetitions of the signal. These controls are typically not necessary for choruses that use a small number of repetitions. When there are many repetitions, however, these repetitions may overwhelm the chorused signal. In these cases, the gain can be adjusted down.
  • Right channel gain: Use these controls – the box and the slider – to set the gain that will be added to the right channel repetitions of the signal.

As you change the maximum delay in any of the channels, the minimum delay might change automatically. This is to ensure that the minimum delay is always smaller than the maximum delay. Similarly, as you change the minimum delay in any of the channels, the maximum delay might change automatically, so that it is always higher than the minimum delay.

When the chorus is initially set, the initial delay for any of the repetitions is a random value between the minimum and maximum delay. In this way, the initial delay, at the beginning of playback, for each of the repetitions is different. If playback is stopped and started, then the same random values are used to ensure that the effect has a consistent sound. During playback, the delay amount for each of the repetitions changes at a random rate up to the (maximum) rate of change specified in the dialog, up and down between the maximum and minimum delays.

See Orinj Effects for additional notes on: where Orinj effects can be used, applying effects to mono and stereo waves, and using effects during playback. See Orinj Working with effects for additional information on creating, modifying, moving, removing, and processing effects. See Delay effect for additional information on the different types of delay effects, including the chorus, in audio processing.

Dry and wet mix

The Orinj Chorus supports dry and wet mix changes. That is, you can adjust the mix between the original signal and the chorus signal. See Orinj Effects for more information.

In version 2 of Orinj, there are no controls for the gain of the repetitions.
