Discusses the DUAL FADER modes of crossfading, panning, ring-modulation. VCAs: linear and exponential. The DUAL FADER consists of two inputs and two outputs. Switching is achieved through the normalisation of connectors. Using two main knobs on the DUAL FADER you can create a crossfader, panner and a ducker. The second of the two knobs increases input sensitivity (20 dB) of the secondary input in order to connect a line level instrument (laptop, MP3 player) and also increase the 1 volt per octave ratio.
Three main functions :
1. CROSSFADER (4’22)
An example of a control voltage crossfader on the DUAL FADER is demonstrated by mixing two signals together across the audio outputs of two oscillators modulated by the TRIPLE LF-VCO.
2. PANNER (6’12)
Voltage controlled distribute of a single signal to different processes. For example, 24dB filter, or a pitch shifter etc. An example of panning is demonstrated by using a LFO to modulate the A1 and B1 stereo outputs of the DUAL FADER.
Dynamic level changes can be used to alter pitch (7’05). Starting with slow panner with a sine wave is gradually speeds up the resulting in amplitude modulation. A multiplication of two waveforms reveals upper and lower side-band frequencies. Similar to
ring modulation and FM modulation made-up of enharmonic partials.
3. DUCKER (9’24)
Two signals are ducked in stereo.
Adding gain to external signals, external signal as an FM source.
Using one oscillator modulated using VC produces super complex sounds.
Experiment with the DUAL FADER on Hordijk system to produce drones and soundscapes.
Q: What are the three additional settings on the side of the DUAL FADER? A: Along with the two main knobs to create cross fader, panning and ducker.
Extra functions to alter the sensitivity to a balanced line level and signal levels. Basically, changes the audible and non-audible range of signals.
