"Are you bored of the monotonous sound of every day life? Do you have a lack of bleepy weird sounds? Are you longing for the rhythmic trotting of robotic communications from beyond our solar system? Then this is the device for you!

Green Dungeon Alchemist Laboratories 8159R RHYTHM-O-TRON

Built from the finest found junk and stuff, this device utilizes the earliest in logic technologies to create rhythmic sequences of bleeps and wails unlike anything heard before! (unless you had an old 300 baud modem) It generates a constantly changing rhythm controlled by four binary inputs, each connected to one of 12 tempo division outputs via bolts. The connection leads are constructed from modified spent bullet casings and the finest quality bits of wire found in the lab. The sound being rhythmized is generated by 3 oscillators with frequency control (marked A, B and C). Combined via a method of ring modulation they provide us with interstellar cosmic sounds and roboitc cybercommunication noises equating to a funky beat to do the robot to! This device also has the capacity to raise the tempo frequency beyond sub-audible normal operation to provide truly unusual electronic buzzing.

An instructional image is provided below along with photographs and sound samples.

Sequence 1 (9:14)

Perhaps this will be of any help anyway."

DARK ENERGY II Initial Specs Released

follow-up to this post.

via Doepfer:

"preliminary without obligation

The Dark Energy (I) has to be discontinued because an important electronic part (CEM3394) is no longer available. We are working on the redesign of the Dark Energy at full speed. The new Dark Energy II will look like the Dark Energy I at first sight. Only the function of some controls and switches will differ from the Dark Energy I. These are the most important differences between Dark Energy I and II:

12dB multimode filter with lowpass, notch, highpass and bandpass (instead of 24dB lowpass of Dark Energy I)
the previous LM control of the filter becomes the filter type control (continuous crossfade lowpass - notch highpass - bandpass)
the LM function of the filter is no longer available
the waveform switch is used to select between saw and clipped/distorted saw (in the center position the saw is off)
the basic waveform of the VCO is saw (not triangle like the Dark Energy I).
because of the pure analog circuit and the temperature control it takes about 30 minutes until the VCO is in tune.
the VCA has a exponential scale (not the combined linear/exponential scale of Dark Energy I)

All other functions will remain unchanged. Even the price will be the same (currently Euro 428). The Dark Energy II will be probably available summer 2012."
