CHAOS Controls
FEEDBACK SECTION
FEEDBACK – use this control to set the probability level of the voltage and
(26)
trigger sampling between totally random at extreme CCW and CW and
entirely locked at 12 o'clock.
FEEDBACK CV – use this input to adjust the feedback settings with an
(27)
external control voltage in the range -5 V to +5 V.
t FEEDBACK – use this button to apply the feedback settings from controls
(28)
26 and 30 and CV 27 to the trigger generator.
X FEEDBACK – use this button to apply the feedback settings from controls
(29)
26 and 30 and CV 27 to the voltage generator.
LENGTH – use this control to set the loop length, from 1 step to 16 steps.
(30)
SAMPLING SECTION
SAMPLE – use this button to either sample a voltage on the Spread CV
(31)
input (17) for use by the voltage generator, or to input custom scales (see
Scales below)
SCALES
The CHAOS comes loaded with six preset scales to be used by the voltage generators.
Each has C as a root note, so in order to use different keys the Steps control (19) should
be turned fully CW with no external CV applied in order to obtain a root note output.
Your audio source can then be retuned to the desired key.
The six scales are accessed by pressing and holding the Range button (18) for two
seconds, then using the same button to step through the scales. The color and
flash rate of the button surround indicates which scale is selected:
• Major (Orange, slow flash): C, D, E, F, G, A, B, C
• Minor (Red, slow flash): C, D, Eb, F, G, Ab, Bb, C
• Pentatonic (Green, slow flash): C, D, E, G, A, C
• Pelog Gamelan (Orange, fast flash): C, Db, Eb, G, Ab, C
• Raag Bahar (Red, fast flash): C, D, Eb, F, G, A, Bb, B, C
• Raag Shri (Green, fast flash): C, Db, E, G, Ab, B, C
Not pressing the button for more than two seconds will exit scale selection. Please
note that the scale is not stored and will revert to last used when the CHAOS
is next powered up. To reset scales back to factory settings press and hold the
Sample button (31) for two seconds, release, and press again until the Range
button LED (18) stops flashing.
Custom scales can also be programmed into the CHAOS. Apply a CV from a suitable
keyboard, such as the Behringer Swing, to the Spread CV input (17) and a gate
from the same source to the X Clock input (21). When you are ready press and hold
the Sample button for two seconds. The button surround will flash when ready to
sample. Play the scale that you wish to use. It is recommended that at least fifty notes
are played, and that notes you wish to sound more often are played more often. For
example, if C3 is wanted twice as often as C4 then play sixteen C3s and eight C4s. This
means that C3 has twice the likelihood of being played than C4. Press the Sample
button again to end recording. Please note that your custom scale is not stored when
the CHAOS is powered down.

HINTS AND TIPS

• Keep the Feedback control (26) just before or after 12 o'clock for slow variation
of the loop.
• The Y output can be used as a modulation source for any of the CV inputs.
• When clocked internally the three voltage outputs are rhythmically
independent, so can produce polyrhythms.
• The feedback loop can be reset at any time in operation by pressing buttons
28 or 29 twice in quick succession.
