11. Processing external audiosignals
You may use the input socket „external audio“ to process audiosignals of other soundsources within Dark
Energy.
Connect e.g. a drumcomputer or an output of your soundcard to Dark Energy‘s external audio input. Start
e.g. a drumloop. The signal runs through Dark Energy‘s filter and is, depending on the Freq.-knob setting,
changed in timbre. Since the VCA knob is cranked up, the VCA is open without getting a control voltage
from the envelope resp. you do not have to play a note on your keyboard. Use linear frequency modulation
of the filter cutoff (LM) to change timbre and add noise to the drumloop.
If you play a note on your keyboard, the envelope opens the VCF and VCA and the loop gets a contour.
Loudness can be controlled with the VCA knob. Program notes in your MIDI sequencer „in parallel“ to the
drumloop or play precise enough on your keyboard to achieve rhythmic effects in sync with the loop.
Instead of the envelope, you can also use Dark Energy‘s LFOs as modulation sources. The squarewaves
provide interesting gate-effects, however perfect syncing the effect to the tempo of the external source is
not possible. So this works well for non-rhythmical sounds.
Of course you may use an external soundsource together with Dark Energy‘s internal VCO. A second ex-
ternal VCO (e.g. Doepfer A-117 or A-118 controlled by CV1 of Dark Energy‘s USB/MIDI-CV interface) or a
noise generator (e.g. Doepfer A-183-1) can also be used. These additional modules can easily mounted in
e.g. a Doepfer A-100 mini-case.
