Mutable Instruments Beads, Manual

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
