Turing Machine Expanders Explained: Pulses Expander and Volts Expander

The Turing Machine becomes significantly more powerful when used together with its expanders.

The Pulses Expander converts the internal states of the Turing Machine into trigger and gate signals.

Each output corresponds to a specific logical state inside the sequence. Some outputs react to individual states, while others combine multiple states using logical conditions.

This makes the Pulses Expander useful for:

  • Triggering percussion

  • Activating envelopes

  • Switching voices

  • Creating rhythm variations

  • Driving probability-based structures

The Volts Expander focuses on voltage generation rather than triggers.

Five adjustable controls allow selected voltages from the sequence to be scaled and shaped. Instead of accepting completely unrestricted random values, the musician can influence the range and behaviour of the generated control voltages.

This makes it easier to create:

  • Controlled melodies

  • Limited pitch ranges

  • Musical modulation sources

  • Predictable harmonic movement

Together, the two expanders transform the Turing Machine from a random CV generator into a complete ecosystem for generative sequencing, rhythm generation and musical modulation.
