pitch shift
For the category
Pitch Shift
the following parameters are available.
Pitch Shift :
This parameter determines the amount of positive or negative pitch shift for
the shift. Expressed in semitones. Range [-12.0 .. 12.0] smt.
Pitch Trim :
This parameter detunes the pitch shift established by the Shift Semi or Pitch
Shift parameters. Range [-50.0 .. 50.0] cnt
XFade Time :
This is used to control the crossfade time of the splice. In general a short
crossfade is desirable, but more complex material may need longer crossfade
times. Range [2.0 .. 15.0] ms
Lowest Shift Frequency :
This tells the shifter the lowest frequency that it may be required to shift. As
a general rule of thumb, this should be set in the higher part of the range in
order to preserve detail in the shifted material. It should be lowered if artifacts
appear in the low frequencies. Range [20.0 .. 250] Hz
Smart Shift :
This tells the shifter to use smart (content-based) pitch shift or blind shift. In
most cases, ‘smart’ is the better choice. Range [ On .. Off]

pitch effects
For the category
Pitch Effects
the following parameters are available.
Delay Time :
Controls all delays in the algorithm. Each voice has its nominal delay time
adjusted by this percentage. Range [0 .. 100] %
Pitch Shift : :
This parameter determines the amount of positive or negative pitch shift for
the shift. Expressed as a percentage. Range [0 .. 100] %
Delay Feedback :
Controls all delays in the algorithm. Each voice has its nominal feedback gain
adjusted by this percentage. Range [0 .. 100] %.
Mst Diffusion :
Input diffusion is the first part of processing for any signal entering a delay.
It can be described as a smearing or softening of the signal and is typically
used to lessen the impact of strong transients. Range [0 .. 100] %.
On stereo
and surround engines only.
Delay Level :
Controls all delays in the algorithm. Each voice has its nominal gain value
adjusted by this percentage. [0 .. 100] %.
On stereo engines only.
Voice Frequency :
The delay voice output signal is filtered by a one pole low-pass. This is the
filters cutoff frequency Range [50 .. 20’000] Hz.
On stereo and surround
engines only.
FB Diffusion :
Feedback Diffusion is similar to Input Diffusion, except that it is applied to
a delayed signal that is being added back into the input. Range [0 .. 100] %.
On surround engines only.
