When grain density reaches audio rates, the DENSITY CV
input (5) applies exponential FM on this rate, with a scale
of 1V/octave.
In this mode, the grains are generated continuously, at a
rate set by the DENSITY knob [D] and modulated by the
DENSITY CV input (5).
At 12 o’clock, no grains are generated. Turn DENSITY CW
and grains will be generated at a randomly modulated rate,
or CCW for a constant generation rate. The further you turn,
the shorter the interval between grains, reaching at the
extreme the period of a C3 note.
Clocked
When latched grain generation is enabled, and when a
signal, such as a clock or sequence, is patched into the
SEED input (4), the DENSITY knob [D] is repurposed as a
divider or probability control. At 12 o’clock, no grains are
generated. Turn CW to increase the probability (from 0% to
100%) that a grain is triggered by the external signal. Turn
CCW to increase the division ratio, from 1/16 to 1.
Gated and triggered
Disable latched grain generation with a short press on the
SEED button [C].
Grains will then be generated only when the SEED button is
held, or when a gate signal patched in the SEED input (4) is
high. The DENSITY knob [D] controls the repetition rate of
grains. When DENSITY is at 12 o’clock, only a single grain
will be played at each press of the SEED button, or at each
trigger sent in the SEED input (4).
