<<< Pro Tip >>>
You can patch both the main Audio Output and Reflect Send to your audio output module for a
pseudo-stereo effect. You can add even more complexity and variation by patching the Reflect
Send to a multiple, patching one copy of the signal to one of your audio outputs along with the
main out (for example, Main out to your left output and a mult of the Reflect Send signal to your
right output). Then, patch another copy of the Reflect Send signal to some external processing
such as a filter or VCA and then back into the Reflect Return. (((( Ambient Stereo Ritual ))))
<<< Modes >>>
1. Unquantized: Smooth, unquantized response
over the operating range
2. Unquantized with Slew: Smooth,
unquantized response over the entire
operating range, but with a musical slew
that is reminiscent of turning the varispeed
knob on a vintage British tape delay. The
"Drag" will lag behind the knob or CV
changes, but then quickly catch up.
3. Unquantized Volt/Octave: Smooth and
unquantized, yet scaled to align with
the 1v/octave curve to allow melodic
modulation of audio in the buffer, or control
the frequency of self-oscillation like a
voltage controlled oscillator
<<< Voltage Control >>>
When using control voltage, the knob associated with that parameter will act as an offset.
Therefore, you will want to adjust the knob and the dedicated inverting attenuator to bring the
control voltage to the desired operating range for the parameter. It is helpful to start with the knob
in the 12 o'clock position and the inverting attenuator fully clockwise, and adjust as necessary.
<<< Self-Oscillation >>>
It is normal for the Afterneath Module to self-oscillate when using higher settings of the Length
and Reflect controls – especially when both controls are set above the 12 o'clock position. When
you combine the self-oscillation with CV control over the Drag parameter you have an interesting
voltage controlled oscillator. Modes 3-9 will allow the self-oscillation to track volt/octave scaling.
When using an external control voltage, the Drag knob acts as an offset control for the incoming
voltage. Due to the nature of the effect, the Drag parameter responds to only positive voltages
between 1.6 and 4.1 volts. When using a voltage between 0 and 1.6 volts, you can turn the Drag
knob clockwise to offset the incoming voltage to the response range. Please note that bipolar
signals may need additional offset voltage from an external source to bring the entire control
signal within the response range.

4. Chromatic Scale: Quantized 1v/octave to
the chromatic scale
5. Major Scale: Quantized 1v/octave to the
major scale
6. Minor Scale: Quantized 1v/octave to the
minor scale
Pentatonic Scale: Quantized 1v/octave to

the pentatonic scale
8. Octaves & Fifths: Quantized 1v/octave to
omit all but octaves and fifths
9. Octaves: Quantized 1v/octave to omit all
but octaves
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, Reflect and Dampen controls. Careful adjustment of the Length and
Reflect 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 Reflect 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 find 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 Reflect 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 Reflect knobs clockwise will result in the sound being sustained in the buffer for longer
periods of time. Higher settings of the Length and Reflect 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!
