2.6. All-Pass Interpolator Chorus Tab
In addition to the SplitMod function which modulates the IRs, a standard chorus is provided for
additional thickness. Three chorus modules are provided and are arranged as follows:
• Post: Connected in series after mix of IR1 and IR2.
• IR1: Connected to the outputs of IR1 (after the mix of IR1-A and IR1-B, if applicable).
• IR2: Connected to the outputs of IR2 (after the mix of IR2-A and IR2-B, if applicable).
Many chorus effects use linear interpolators; these can sometimes introduce aliasing or other types
of distortion into the signal path so here an all-pass interpolator is used. These are more
computationally expensive but tend to sound better than using standard linear interpolation.
The traditional chorus controls are provided where a delay line of a certain length is modulated by a
given amount at a given rate. Additional controls are provided to control feedback (from a static
point half-way through the delay line) and a width control to control the stereo spread of the effect.
The Copy/Reset button provides a facility to reset individual elements of the chorus and to copy
setting to an internal clipboard. Once a setting has been copied to the internal clipboard from the
Post, IR1 or IR2 chorus modules it can be pasted to any of the Post, IR1 or IR2 chorus modules in
order to facilitate simple duplication of settings.
