  • Two-channel modulation source for random control voltages
  • Each channel consists of a random generator that generates smoothed random voltages and interpolates between the random values
  • Parameters per channel: Frequency, Level (VCA), Offset (+/-5V), Curve (form of interpolation) and Limit/Fold/Thru toggle switch
  • LED displays and CV inputs with attenuators for frequency and level per channel
  • Wave output, inverted wave output and gate output per channel as well as two averaged outputs (AB Average and Inverted Average)

RANDOM BEZIER WAVES

This module started with an idea from Rijnder Kamerbeek aka Monotrail, a straightforward random generator with interpolation between random points making it something like a complex, ever evolving, LFO

The concept is simple. It contains two identical smooth random voltage generators. Each has a frequency, level, offset and curve control. The frequency control sets a steady pace with which bipolar random voltages are generated. The level control works like an attenuator/VCA on the output, reaching from max output to closed. The offset allows shifting the whole wave up and down on the voltage range. Curve determines the shape of the interpolation.The bipolar activity on the main outputs as well as gate outputs are visualised with LEDs.

Both Frequency and Level controls have a CV input with attenuator. When there is nothing patched into the CV inputs, these are internally connected to the main output of the other channel. This normalization makes it very easy to add randomization to the frequency or level for more depth, or of course, add cross-modulation for chaotic voltages.

The output VCAs are usefull to dial in subtle and time-based modulation without the need for external VCAs. For example, to modulate the amount over time with an envelope, or use the other generator with slower speeds to add random changes to the level of a random voltage.

Both generators also have two other outputs. One is an exact inversion of the main output, so it responds to the level and CV input. This is great for stereo or inversed effect patches. The other is a simple pulse output, here there are two different behaviours, channel A outputs a pulse at every random generation, channel B acts like a comparator. Whenever the main is positive this comparator output is a high gate. And whenever the main output is negative or close to 0, there is no gate output. Great for random triggers or firing other events like envelopes.

A couple other outputs are also available and are obtained by averaging both channel main outputs. The first output is the average while the second is an inverted average.
