Random from Mosaic is based on Buchla's Source or Uncertainty and offers drei verschiedene Zufallsspannungen . The 1U module has its own clock generator, ranging from about 30 seconds to audio, which can be replaced by an external clock signal. Gate, stepped and smoothed random are output in parallel. Smooth and stepped are adjustable in their intensity. If you need a certain unpredictability in your patches, Random is a good choice.
