TLDR:

"Random modules generate unpredictable signals - from stepped voltages to smooth fluctuations - great for creating evolving, generative, or chaotic patches."

What Is Random Voltage?

Random sources generate unpredictable control voltages. They’re great for modulation that feels organic, generative, or just straight-up chaotic. Some random is stepped (changes suddenly), some is smooth (drifting), and some is clocked (S&H-style).

Types of Random

• Stepped Random: Sudden voltage changes - often clocked or sampled.
• Smooth Random: Like a drunk LFO. Gradually drifting signal.
• Quantized Random: Random CV snapped to a musical scale or volt-per-octave step.
• Boolean / Gates: Random triggers or gates - like coin flips, bursts, or probabilistic clocks.

Uses in a Patch

• Random pitch (quantized or not)
• Wiggly modulation for filters or wavefolders
• Creating generative melodies or textures
• Trigger random drum patterns or ratchets

Random isn't just for weirdness - it's for variety. Add a little unpredictability and your patch starts breathing.
