The Mod Page
Grains
You can specify the number of grains, from 1 to 8. For example, with a setting of 4,
you get 4 grains per period of the grain duration.
To hear the effect of this setting, you have to play a new note.
The Mod Page
The Mod page contains the LFO settings in the upper section and the mod wheel, or
vibrato, settings in the lower section.
LFO Settings
LFO Waveform and Shape
Here, you can select the waveform for the LFO:
Freq
Controls the frequency of the modulation, that is, the speed of the LFO.
Sync
When Sync is activated, the frequency is set in fractions of beats.
Position
Controls the modulation depth of the grain position modulation.
Formant
Controls the modulation depth of the grain formant modulation.
Option Description
Sine This produces smooth modulation, suitable for vibrato or tremolo.
Shape adds additional harmonics to the waveform.
Triangle This is similar to Sine. Shape continuously changes the triangle
waveform to a trapezoid.
Saw This produces a ramp cycle. Shape continuously changes the
waveform from ramp down to triangle to ramp up.
Pulse This produces stepped modulation, where the modulation switches
abruptly between two values. Shape continuously changes the ratio
between the high and low state of the waveform. With Shape set to
50
%, a square wave is produced.
Ramp This is similar to the Saw waveform. Shape increasingly puts silence
before the sawtooth ramp up begins.
Log Shape continuously changes the logarithmic curvature from
negative to positive.
S & H 1 This produces randomly stepped modulation, where each step is
different. Shape puts ramps between the steps and changes the
S
& H into a smooth random signal when fully turned right.
S & H 2 This is similar to S & H 1. The steps alternate between random high
and low values. Shape puts ramps between the steps and changes
the S & H into a smooth random signal when fully turned right.
