voltage-controlled pseudorandom pulse and pitched noise generator.
the design of this module was inspired by the logically economical and timbrally memorable sound generation method of atari's 8-bit computers, also found on their 2600 and 5200 series video game systems. the
four parallel audio outputs operate with similar spectral behavior and a much-improved frequency resolution. this section of the module offers several different flavors of pitched audio noise with varying
degrees of periodicity. toggle switches are available for changing the behavior of each output, from more noisy behavior to a pure square wave. manual and voltage control of the audio frequency is
the upper section of the zorlon cannon operates upon the same principles, at a much lower rate. each of the outputs here generates a 12 volt gate signal at a pseudorandom interval, with each output offering a
different sequence length. in addition to voltage control of the update period, you may adjust the seed value for a different repeating sequence of gates.
nine outputs: clock output, 4x random pulse outputs , 4x pitched noise outputs (4, 5, 17, and 9 bit sequences).
manual and voltage controlled master clock frequency (for each section) and seed value.
toggle switches for different combinations of pitched noise.
+/-12v doepfer-style power connector
5v power supply encouraged. onboard regulator available otherwise, 5v power source selectable by jumper.
panel size: 11hp
pitched noise section:
+5: use the toggle switches to modify each output! each switch adds an additional stage of logical and with the 5-bit output for less periodicity, with the switch for the 5-bit output allowing passage of a pure
square wave instead. for the two longer outputs, the switches enable divided-down bass sounds similar to your favorite single-bit sound generators.
digital noise: use the 17-bit output for classic "grey noise" effects, carrying a very particular spectral distribution in contrast to its analog counterparts.
random gates section:
random sequence: patch each of the four gate outputs into a module such as a doepfer a-138c polarizing mixer, and set the levels as desired. patch the output of the mixer into the cv input of your favorite
oscillator. the effect is similar to that of blacet's "binary zone", only with random availability of each voltage level with a very long period for the combined "sequence".

here are some demonstration sounds from the manufacturer:
1. audio clip one
the four gate outputs are set to trigger four external egs controlling four external vcas governing the level of each of the four audio outputs. some fm is added here and there.
2. audio clip two
similar patch as above, but the envelopes (doepfer a-143-1) are set to self-trigger instead. the audio mode switches are played with.
