number generators is commonly used in synthesizers, in fact many analog synthesizers from the past used
digital random number generators to produce audio noise. This type of generators is sometimes named
pseudorandom, as the sequence will eventually repeat itself. In practice, if the rate of a random signal
generator is set to 1000 Hz a sequence on the G2 will last over four and a half hours. In this case a
thousand random values a second would be produced, making the amount of data simply too much for
the human brain to ever notice any repetition, meaning that for musical purposes the signal is random
enough. Still, within such a sequence there might be tendencies to cluster short and almost similar
patterns or motifs. This is caused by how a number of consecutive values appear as a group. The Rnd 1
setting is virtually free of such motifs, but the Rnd 2 setting does exhibit clusters of values that show some
similarities. When in Rnd 2 it might appear that there are little upwards arpeggios now and then, all of
slightly different lengths and different shapes and at irregular intervals, but still appearing as the sort of
motifs a musician would name arpeggios.
The Rnd 1 and Rnd 2 settings use different methods to generate the values. The Rnd 1 setting uses what
is named a linear congruential method, while the Rnd 2 setting uses a shift register method.

INPUT
At the explanation of the Character parameter it was said that the string of random numbers
forms a very long sequence. When a trigger signal is applied to the Rst input the sequence will
restart at the point where it starts on patch load or after a recalculation of the patch. When a control signal
is connected to the Seed input, the trigger on the Rst input would cause the module to start at a different
position in the sequence. This start position is defined by the momentary value on the Seed input. The
value at the Seed input is commonly named the seed. Note that the Seed input must be used together
with the Rst input to do the job. The actual seed can be any possible fractional value between the positive
and the negative clipping level of the G2 system, meaning that there are many million start positions
possible, depending on the value on the Seed input. The sequence will always develop in the same way
from the start position defined by the seed.

The RndClkA module is fitted with a Dice button. The Dice button can be used to manually
advance the pattern by one extra step in between the steps generated by the module itself. When
this button is assigned to a button on the G2 panel and pressed, mouse-clicked in the editor program, or
assigned to a

Out module, the module will step to the next position in the sequence.

This random wave shape module produces a random
waveform that is stepped when Edge is at 100%, slewed
between steps for the settings 25%, 50%, and 75%, and
a smoothly gliding random wave when Edge is at 0%. When Step is at 100% the difference between the
current and the next random values can be quite big, while a Step setting of 25% generates much smaller
steps. The rate of the module can be patched to track the keyboard by connecting the Pitch output on a
Keyboard module to the Pitch input on this module.

The modulatable random wave shape module is quite
similar to the LfoA module in Random Steps or Random
waveform mode, but with the added Step and Edge
