With a duration of 1 and a Key Follow setting of 100 %, for example, the difference in
pitch between two keys is one semitone, which corresponds to the standard keyboard
tuning. Longer durations lead to an audible volume modulation that is different for the
different keys. To apply the same volume modulation with each key on your keyboard,
set "Key Follow" to 0 %.
The center key for this function is C3, therefore, C3 is always played at the set
duration, regardless of the "Key Follow" setting.
Duration Random
The random grain duration is calculated separately for each channel, at the start of a
new grain. This can be used to widen the panorama of the sound. At a setting of
100 %, the grain duration varies between half and twice the grain period.
Duration Spread
This parameter is available when "Number of Grains" is set to a value higher than 1. It
modifies the grain durations by the factor you set. This way, each grain is played with
a different duration. A setting of +100 % corresponds to twice the original duration,
and a setting of -100 to half the original duration.
For short grains with a duration of 1, lower Spread values result in slightly different
pitches for the different grains. Higher Spread values are perceived as the sound
being detuned.
Pitch Settings
In granular synthesis, you have two different approaches to define the pitch of a
sound: It can either be the pitch of the original sample or be defined by the grain
oscillator.
• To use the pitch of the original sample, raise the Duration value until you can
clearly hear the sample's own pitch.
• To define the pitch using the grain oscillator, set Duration to very low values,
preferably 1 or 2.
Pitch Interval
Here, you can specify an interval between -12 and +12 semitones. The grains are
played randomly at their original pitch, or are transposed according to the pitch
interval. This interval is calculated separately for each channel of the sample, at the
start of a new grain.
Pitch Random
Sets the random pitch range in semitones and cents. At a setting of +12, the random
pitch values lie between -12 and +12 semitones. The random pitch is calculated
separately for each channel of the sample, at the start of a new grain. This can be
used to widen the panorama of the sound.
Pitch Spread
This parameter is available when "Number of Grains" is set to a value higher than 1. It
detunes the pitch of the grains in semitones and cents. The first grain keeps its pitch,
and the other grains are detuned evenly to values within the specified range. The last
grain is detuned to the maximum value.
For shorter grains, this is perceived as a change in the spectrum and for longer grains
as a detuning of the sample.
