The Pitch Shifter also allows you to select the source of the pitch data that the shifter will use when
making pitch calculations. The global detector is unaffected by routings and is usually the best
choice for single note usage. The integrated detector uses the signal input to the pitch block
including any feedback within the block. This can enhance pitch stability when using feedback,
whether internally, using the
FEEDBACK parameters, or using the feedback blocks. When using
the global detector and pitch feedback the pitched notes may sound a bit off if you stop playing since
there will be no signal to determine pitch from. By using the internal detector the pitch block is
always obtaining pitch information even when you stop playing.
The integrated detector may not work as well, however, if the data input to the block is distorted in
amplitude or time (i.e. reverb, chorus, etc.).
The
PITCH SOURCE
parameter has three settings:
GLOBAL
- In this mode the pitch information comes from the global pitch detector connected
directly to the main inputs. This detector is optimized for speed and accuracy when playing single
notes.
LOCAL MONO
- In this mode the pitch information comes from the integrated pitch detector
connected to the input of the pitch block. In this mode the detector is optimized for speed and
accuracy when playing single notes. By using the input of the block as the data source this detector
can continue to track pitch if you are using feedback or a delayed signal into the block and stop
playing.
LOCAL POLY (Ultra Only)
- In this mode the pitch information comes from the integrated pitch
detector connected to the input of the pitch block. In this mode the detector is optimized for
polyphonic sources, i.e. chords. The pitch tracking is necessarily slower with more latency but is
more stable when playing multiple notes. Due to the inexact definition of pitch for chords, the pitch
detector may have difficulty finding pitch on complex chord types. Simple chords, diads and triads,
work best.
Common Parameters
The first menu page has several common parameters for the pitch block.
TYPE - Sets the sub-algorithm to use.
INGAIN - Sets the input level to the block. You can use this to control the amount of signal input to
the pitch shifters. Often times this is attached to a modifier to allow swell-type effects.
PITCH SOURCE - Selects the source of the pitch information. See description above.
Detune
The Detune mode creates two voices that are slightly detuned from the input. The amount of
detuning is adjustable between -50 and +50 cents. This mode is useful for creating double-tracked
sounds or chorus-like effects.
VOICEn DETUNE - Sets the detune amount for each voice. Attaching an LFO to these can be used
to create chorus effects.
