Random * Source APNC is a very useful composite module of 5 Serge modules, including 2 new 3th generation modules.
The left section, Serge ACPR, is a precision linear crossfader for CV / audio signals. The new version, designed by Serge in 2017, has significantly improved accuracy. With smooth changes to the two CVs, wave blending in the audio range, and wave shaping with CV and audio inputs, this module plays an important role in complex patches.
The middle section, Serge NOI, produces white noise and pink noise waveforms. The S / H SRC output produces an equal probability random voltage with a distribution function close to 1 / F required as an input source for the sample and hold function, and is particularly effective in combination with the Smoothed & Stepped Generator (SSG).
The section on the right, Serge CV-PRO, is also a newly developed module that goes beyond CV addition / inversion. The 1V / OCT (Precision) input stage provides a 1V / Oct control voltage mixing function that accurately transposes the sequence in cents while maintaining tuning. You can also accurately transpose the signal up or down an octave by operating the OCTAVE switch. Three attenuverted stages provide complete processing control over input voltage levels and polarities with Serge's unique diode-based wave compression.
