Set Next
This control sets whether the random value replaces the step value that the LFO just
stepped to, or the following step value. This makes more sense when the Interpolation
mode is Linear.
Mode
There are two modes, Rotate Right and Rotate Left, which are fairly self-explanatory - they
simply control in which direction the bits rotate. Because the right-most bit is always the
least significant bit of the DAC, different rotation directions tend to produce different
sounding patterns.
Length
The ‘Length’ knob sets the number of bits in the shift register, from 1 to 48.
DAC Bits
The ‘DAC Bits’ knobs sets the number of bits that are the input to the DAC. This sets the
number of possible different values that the random output can take e.g. an 8 bit DAC can
output 256 different values; a 1 bit DAC can output 2 values (just on or off).
Randomness
This is the setting that is often CV-controlled in a hardware implementation, as it controls
the tendency of the random pattern to evolve.
At a setting of ‘0.0’ the chance of a bit being inverted is exactly 50%. This is maximum ran-
domness.
At settings higher than 0.0, the chance of a bit being inverted gets gradually less, meaning
the pattern tends to change less often. At a value of 1.0, the chance of a bit being inverted
is zero, and the pattern is fixed.
At settings lower than 0.0, then chance of a bit being inverted gets gradually more, which
again means that the pattern tends to change less often. At a value of -1.0, the bit is always
inverted, which means that the pattern is fixed, and twice as long as the register length -
the pattern plays alternately inverted and non-inverted.
Editing the bits with the mouse
You can directly edit the bits in the shift register by clicking with the mouse. (Clicking and
dragging the mouse in the shift register has the same effect as clicking in each bit position
that you drag over.)
A simple click will invert the bit under the mouse. Shift+click sets the bit (i.e. turns it on).
Option (OS X)/Control (Windows)+click resets the bit (i.e. turns it off.)
