Doepfer random voltage extender module.
Jonathan64 11.09.2013
This module cannot be used on it's own, but rather is intended to provide additional facilities for the A-149.1 which generates random voltages (which can be quantised). It provides eight digital outputs each of which switches at random but synchronised to the clock input of the A-149.1. I have found it useful for generating random "note on" and "note off" signals when creating random self-generating musical sequences (Stochastic music). Used in combination with a logic module A-166 a useful range of signals can be generated at different time intervals to make the music more interesting to the ear, rather than all the notes being the same length. There are numerous other uses for randomly generated logic signals in a modular system apart from triggering envelope generators.

Compagnon gates aléatoires du 149-1
AnalogGuy 06.11.2019
Sans le 149-1 ça ne marche pas. Donc soit vous avez le premier et c'est une super option pour en plus générer des gates aléatoires contrôlées par les réglages du 149-1, soit vous n'avez pas le 149-1... et ce module vous sera inutile... mais alors jetez un oeil sur le 149-1...

Add some randomness to your rig
Monkeproggs 18.11.2020
This module sends gate/trigger signals at random when connected to Doepfer A-149-1. You feed the A-149-1 with a clock and this module spits out random gates/triggers each clock advance.
" It makes available 8 digital random
voltages (i.e. only low/high states like a gate signal)."
This module doesn't send out any random voltages, it sent out 10V on random outputs.
But it is very useful for triggering gates/filters/notes at random. I use it often to trigger the gates in my Behringer Multiple/gate Switch, thereby allowing modulation through at random. I also use it with a Logic circuit to decrease the probability of a output going high. For instance I have one output from this connected to an AND gate and another from my clock divider 1/13 output to the same AND gate. This example would giva a probability of an event happening 1/13+1/X.
The randomness of the outputs are fairly even and sometimes if feels like it is running through a chain, but for the most part it does the job.
I'm very pleased with this module and would higly recomend it to anyone interested in Generative systems or daring explorers.

The only downside is that it seems that all outputs are more prone to turning high than low so if you just use this as a trigger it will be firing a lot. So perhaps buy a logic module as well.

auch gut

als Ergänzung zu A-149-1. Die Ausgänge sind Gates und werden durch den Clockinput des A-149-1 angetrieben.
Sehr brauchbar, um damit z.B. 8 Sequencer eines Z8000 anzutreiben.
Die Gates bleiben 'oben', solange sie an sind. Falls man damit zufällig Noten triggern möchte, könnte man das mit einem A-162 dahinter bewerkstelligen.
