The Dual Digital Shift Register (DDSR) is a shift register based pseudo-random cv and gate generator.
It uses gate signals to create chance operations, generating aleatoric sequences.
It has 2 channels, each with 2 inputs and 5 outputs. The inputs are clock and data.
The outputs are 4 gate outputs, labeled QØ, Q1, Q2, & Q3 and a cv output.
It can be predictable if given closely related signals, which can repeat or sublely morph between different rhythmic expressions. The DDSR settles into patterns and then moves away from them, there are periods when it will grab sequences and loop them. The sequences it creates are based around loops instead of random uncorrelated voltages and because of that the results are musical and familiar.
A sample and hold’s output exactly mirrors the voltage level present at the input. The DDSR creates patterns based on the relationship between the clock and data.
