EQD Afterneath

7
Keep in mind that the Afterneath is not intended to be a precision oscillator. When self-oscillating,
it’s pitch is mostly based upon the note that is played into it. While feeding back, the original
note will transform through various harmonic and enharmonic frequencies, depending on the
levels of the Length, Reect and Dampen controls. Careful adjustment of the Length and
Reect controls can allow you to sustain sounds in the buffer for longer periods of time without
it becoming unstable.
<<< For Volt/Octave Tracking During Self-Oscillation >>>
1. Turn the inverting attenuator for the Drag CV input fully clockwise, and the Drag knob to
12 o’clock.
2. Select one of Modes 3-9.
3. Turn the Length and Reect knobs past 12 o’clock until self-oscillation is heard.
4. Find the range of your CV source (Volt/Octave keyboard, for example) that is having an
effect on the drag control. Pick the highest note that you wish to play in that range and play
it repeatedly while turning the Drag knob back and forth until you nd the upper limit of the
control (This is the point where turning it any further will not have an effect). Place the Drag
knob at the point at which it just passes the point where it no longer has an effect on the scale.
5. Lower the Length and Reect knobs until the self-oscillation is no longer present.
Now, you have scaled the range of the Afterneath module to your CV source. Notes played into
the Afterneath will now be scaled according to the CV present at the Drag CV input. For example,
if you press the “C” key on your Volt/Octave keyboard, and then play a C note from an external
source into the input of the Afterneath module, subsequent key presses on your keyboard will
result in the correct scaling of the sound that is in the buffer of the Afterneath. Turning the Length
and Reect knobs clockwise will result in the sound being sustained in the buffer for longer
periods of time. Higher settings of the Length and Reect parameters will result in self-oscillation
wherein the original sound will transform through various harmonic and enharmonic frequencies
of the original sound that was in the buffer.
Modes 5-9 are an excellent choice for non-keyboard CV tracking to impart cyclical or random
scaled control of the Drag parameter. For example, connecting a source of random voltages to the
Drag CV input will result in the generation of random melodies based upon the scale associated
with the mode that you have selected.
We recommend lots of experimentation!
