CHAOS Controls
Controls
TRIGGER SECTION
- BIAS – use this control to bias the trigger outputs between t1 (output 10) to CCW and t3 (output 12) to CW; t2 (output 11) stays constant.
- BIAS CV – use this input to adjust the bias settings with an external control voltage in the range -5 V to +5 V.
- BIAS TYPE – the trigger bias can be set to one of three types, with the button surround color indicating which is in use:
- Flip (orange) – a coin is flipped at each trigger pulse, with control 1 and CV input 2 determining whether it is more likely to fall on Heads (t1) or Tails (t3)
- Ratio (red) – the settings of control 1 and CV input 2 determine the ratio of triggers generated for t1 at CCW or t3 at CW. The higher the bias, the greater the ratio.
- Alternating (green) – triggers will alternate between t1 and t3, with a greater number of repeats depending on the position of control 1 and CV input 2.
- RATE – use this control to set the internal clock rate of the Chaos, from 63 Hz to 255 Hz (3.78 bpm to 3780 bpm approximately) When using an external clock this control allows adjustment of division and multiplication.
- RATE CV – use this input to adjust the rate settings with an external control voltage in the range -5 V to +5 V.
- RATE RANGE – use this button to divide the internal clock rate by 4 (orange), multiply by 4 (green) or leave it as it is (red). The button surround color indicates which is selected.
- JITTER – use this control to introduce an element of randomness into the clock rate (internal or external). Turning the control CCW will cause clock steps to lag behind the beat, while CW will cause them to move ahead.
- JITTER CV – use this input to control jitter from an external CV source, in the range -5 V to +5 V.
- CLOCK – use this input to replace the internal clock with an external one.
- (12) – TRIGGER OUTPUTS – use these outputs to access triggers t1, t2 and t3. Press and hold button 3 (Bias Type) and use the Bias control (1) to adjust the trigger duty from 1% to 99%, with 50% at 12 o’clock. Press and hold button 3 and use the Jitter control (7) to randomize the trigger duty, with higher settings giving greater randomization. When the internal clock is used the three trigger outputs trigger the three voltage outputs.
VOLTAGE SECTION
(13) BIAS – use this control to bias the voltages output on outputs 22 to
24 between lower voltages to CCW and higher voltages to CW.
(14) BIAS CV – use this input to adjust the bias settings with an
external control voltage in the range -5 V to +5 V.
(15) CONTROL REACTION – the way in which the three voltage outputs 22 to
24 react to the settings of controls 13, 16 and 19 (and their associated CVs)
can be set in three ways, with the button surround color indicating which is
in use:
- As Controls (orange) – all settings exactly follow the controls.
- Equal and Opposite (red) – X2 output (23) follows the controls exactly, while X1 (output 22) and X3 (output 24) do the exact opposite.
- Sliding Scale (green) – X1 output (22) follows the controls exactly, while X3 (output 24) does the exact opposite and X2 (output 23) lies between the two other outputs.
(16) SPREAD – use this control to set the distribution of the control
voltages. Turning the control CCW will bias the voltages to the center of
their range, at 12 o’clock the full range is used but still with a bias
towards the center. Going further CW allows more extreme ranges to be used.
(17) SPREAD CV – use this input to adjust the spread settings with an
external control voltage in the range -5 V to +5 V. Spread CV can also be used
to apply a random value to the X outputs by pressing button 31 to sample the
CV input.
(18) RANGE – use this button to set the Chaos’ voltage range. Choose from
0 V – +2 V (orange), 0 V – +5 V (red) or -5 V – +5 V (green). The button
surround color indicates which is in use. This button is also used to select a
preset scale (see Scales below)
(19) STEPS – use this control to select how the Chaos steps between
voltages. At 12 o’clock the steps are instantaneous in time with the clock
used. Turning the control further CCW will add a portamento-like smoothness to
the transitions, with more extreme settings generating random smoothed
voltages. Turning CW quantizes the voltages to a selected scale (see Scales
below) with the highest setting producing a single, root note.
(20) STEPS CV – use this input to adjust the steps settings with an
external control voltage in the range -5 V to +5 V.
(21) CLOCK – use this input to clock the voltages X1, X2 and X3 from an
external clock rather than from t1, t2 and t3.
(22) (24) – VOLTAGE OUTPUTS – use these outputs to access voltages X1, X2
and X3.
Y SECTION
(25) Y OUTPUT – the Y output is a voltage output, separate to the X
outputs, but related to X2. It operates over the range -5 V to +5 V and can
have its parameters adjusted by pressing and holding the Control Reaction
button (15) and altering the following controls:
- Rate (4) – adjusts the division of X2 that will produce Y from 1/64th to Unity.
- Bias (13) – works as it does with the X voltages.
- Spread (16) – works as it does with the X voltages.
- Steps (19) – works as it does with the X voltages.
FEEDBACK SECTION
(26) FEEDBACK – use this control to set the probability level of the
voltage and trigger sampling between totally random at extreme CCW and CW and
entirely locked at 12 o’clock.
(27) FEEDBACK CV – use this input to adjust the feedback settings with an
external control voltage in the range -5 V to +5 V.
(28) t FEEDBACK – use this button to apply the feedback settings from
controls 26 and 30 and CV 27 to the trigger generator.
(29) X FEEDBACK – use this button to apply the feedback settings from
controls 26 and 30 and CV 27 to the voltage generator.
(30) LENGTH – use this control to set the loop length, from 1 step to 16
steps.
SAMPLING SECTION
(31) SAMPLE – use this button to either sample a voltage on the Spread
CV 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.
IMPORTANT NOTE
Powering up the Chaos while pressing the Control Reaction button (15) will cause the control LEDs to dim and change color. Should this occur power off the Chaos and power up again while pressing the button to return to normal operation.
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.
Power Connection
Connect end P1 to the module socket
Connect end P2 to the power supply
The module comes with the required power cable for connecting to a standard Eurorack power supply system. Follow these steps to connect power to the module. It is easier to make these connections before the module has been mounted into a rack case.
- Turn the power supply or rack case power off and disconnect the power cable.
- Insert the 16-pin connector on the power cable into the socket on the power supply or rack case. The connector has a tab that will align with the gap in the socket, so it cannot be inserted incorrectly. If the power supply does not have a keyed socket, be sure to orient pin 1 (-12 V) with the red stripe on the cable.
- Insert the 10-pin connector into the socket on the back of the module. The connector has a tab that will align with the socket for correct orientation.
- After both ends of the power cable have been securely attached, you may mount the module in a case and turn on the power supply.
Installation
The necessary screws are included with the module for mounting in a Eurorack case. Connect the power cable before mounting.
Depending on the rack case, there may be a series of fixed holes spaced 2 HP apart along the length of the case, or a track that allows individual threaded plates to slide along the length of the case. The free-moving threaded plates allow precise positioning of the module, but each plate should be positioned in the approximate relation to the mounting holes in your module before attaching the screws.
Hold the module against the Eurorack rails so that each of the mounting holes are aligned with a threaded rail or threaded plate. Attach the screws part way to start, which will allow small adjustments to the positioning while you get them all aligned. After the final position has been established, tighten the screws down.
