How Do Bernoulli Gate Networks Create Structured Randomness?

Using Bernoulli Gate Networks in Generative Music

Bernoulli gates are among the most useful probability tools in modular synthesis.

A network of Bernoulli gates can generate surprisingly structured randomness.

Series Connections

When Bernoulli gates are connected in series, each later gate receives fewer opportunities to activate.

As a result:

• Early branches occur frequently.

• Later branches occur less often.

This naturally creates weighted probabilities.

Parallel Connections

When Bernoulli gates operate in parallel, each branch receives approximately equal opportunities.

The resulting activity is distributed more evenly.

Musical Applications

Bernoulli gate networks can control:

• Voice selection

• Melody variation

• Rhythm generation

• Structural changes

Shared Pitch Sources

A particularly effective strategy is allowing multiple voices to share the same pitch source while their activation remains probabilistic.

This preserves harmonic coherence while introducing variation.

Structured Randomness

Bernoulli networks demonstrate an important principle of generative composition:

Randomness becomes more useful when organised.

Conclusion

Bernoulli gate networks provide a practical way to create probability-based structures that remain musically coherent.
