SAMPLES

C# DRONE
turning up the oscillators one by one, followed by noise & filtering

PLINEDA
prelimenary mixdown for the upcoming "Oengis Larc" record
the synth-line is the ShuttleDrone played by a sequencer (doepfer dark time)

BLOCK DIAGRAM:

A simple concept...

A MORE DETAILED DESCRIPTION:

 

OSCILLATOR I

Square wave
tuned to C# when the freq is fully down, range switch up & the fine-tuner somewhere in the middle...

sample: aliens?

 

OSCILLATOR II

Textured square wave with adjustable duty cycle

sample: sweeping the controls

 

OSCILLATOR III

A filtered, more mellow square wave

sample: echo strings
sample
: random sequence & space echo

 

LFO

2 ranges
2 waveforms > square & morphed square
The destination-switch allows for internal routing to oscillator I or the filter.
However, the top-panel enables the other 2 oscillators to be modulated by the LFO aswell...

FILTER

LOW PASS FILTER

I more or less copied this filter-circuit
from Music from Outerspace (WSG)
Just added the color-switch - wich cuts some of the low end, revealing more of the subtleties in the resonance - & a bypass switch (because I usually prefer my moogerfooger to filter this device...)

sample
sequence on oscI

sample
utopia Synth through the filter


 

MIXER

Obviously this mixes the oscillators

The noise control adds hiss
(a filtered white noise generator)

The external input is intended for other raw oscillator-type devices

 

STABILITY

This control adds resistance to the powersource, making the modules unstable

sample

euhm, yes...

TOP PANEL

CV inputs for the 3 oscillators & the cutoff frequency

LFO output - this is wired after the amount-knob, but before the destination-switch. So it can be patched to anywhere regardless of the internal routing

As stated before, the external input is intended for oscillators, it does not take a guitar or synth-signal. (actually voiced it specifically for my Utopia Synth)

 

MAKING OF FEATURETTE:

It started with countless hours of experimentation
 on the breadboard...

...untill I had a final circuit...

...soldered the modules point to point
onto perforated boards...

...marked the holes on the aluminium faceplate
with a drill-punch...

...drilled the holes...

...glued on the legend with tec7
& freed the holes...

...added the controls...

...added some wires...

..added some more wires...
this step took 7 hours of continuous soldering,
only interupted by the occasional sigaret & coffee-refill

...made the wooden case...

...mounted the boards & faceplate...

...hooked everything up...
Several things do not work, shit...

...after a 3-day troubleshoot nightmare
I screwed everything together & added the knobs...
