Coriolis Force

The Coriolis effect is a force that causes objects in motion to deflect in relation to a rotating reference frame.

Turn2on “Coriolis Force” changes the equation of motion for your incoming signal using a number of parameters. Changing the filter frequency and pitch shift parameters downwards / upwards moves your signal to a different location. The hold button stops time, whilst at the same time allowing the main signal to take its own trajectory.

CORIOLIS FORCE is based on a Pitch-Shifter with parallel mode, sustain holder, multimode filter, wah fx and harmonizer.
The Pitch-Shifter’s Coarse and Fine parameters allow individual adjustment of the pitch value of the wet signal for the Left & Right channels. When Parallel mode is engaged, pitch shifting the Left Channel also affects the Right Channel and vice versa. Left and Right pitch-shifter channels have a range of +/-1 octave and have +/-12 semitones fine tuning control. The Pitch-shifter has 4 different Mark modes each with its own frequency characteristics.

When the HOLD button is enabled the wet Pitch-Shifted signal is frozen to a micro loop. A clean dry signal can then be played in parallel to the frozen processed pitch-shifted signal.

In SPECIAL mode, the filter is controlled by the Left or Right Pitch-Shifter parameter. From here it is possible to vary filter modes and routings. This allows emulation of Tape-Stop or Tape-Play effects. If the filter Frequency parameter is controlled using the LEFT PITCH SHIFTER, it works as SUM (Filter+Left Pitch Shifter). The RIGHT channel continues to operate as a simple Right channel Pitch Shifter. And vice versa

Hold control mode is accessible on rear panel. This is used to select between toggle On/Off button and momentary button modes.
Routing mode selects between Off/Main/Post modes of the filter section. In Main mode the wet signal is routed to the Filter. The Filter does not affect the Dry signal. In Post mode both the wet and dry signal are routed to the Filter.
The Filter includes 4 different modes: LowPass (LPX), HighPass (HPX), BandPass (BPX) and XAU (X-Wau) filter.
Coriolis Force’s large number of filter and pitch-shifter modes allow for incredible manipulation of pitch and filter frequencies. The freeze function further enhances the effect increasing the creative possibilities

Coriolis Force is a pretty weird phenomenon however the nature of it is simple: Different parts of the Earth move at different speeds.
The Earth rotates once every 24 hours.

If you stand within a few steps of center at the North or South pole, the speed of your foot is around 8 km/h. If you stand on the equator line, the speed of your foot is around 1673 km/h. Nothing has changed. The Earth is still rotating at the same speed but your travel speed is different depending on where on Earth you are standing.

Anything traveling long distances, such as air currents, ocean currents, airplanes etc. will be pushed out of linear movement due to the Coriolis Effect.
The Coriolis Effect is a force that causes objects in motion to deflect in relation to a rotating reference frame.

HORIZON SHIFT

LEFT & RIGHT CHAN. SHIFT CONTROL: Adjusts the pitch value of the WET signal individually for Left & Right channels. Works in 2 measurement modes 

P.SHIFT VISUALISATION: Visualisation of the L/R channels pitch-shifting values

PARALLEL MODE: When Parallel mode is engaged, pitch shifting the Left Channel also affects the Right Channel and vice versa.

MARK MODEL: Selectable pitch-shifter frequency modes
HORIZON SHIFT: 3 pitch-shifter modes (2 Octaves, Octave Fall, Octave Rise)
MEASUREMENT MODE: Coarse / Fine mode. Coarse: +/-1 octave, Fine: +/-9 semitones. Decimals: +/- 12,0 semitones with steps in decimals (+/-0,1)


SUSTAIN HOLD

When the HOLD button is enabled the wet Pitch-Shifted signal is frozen to a micro loop. 

A clean dry signal can then be played in parallel to the frozen processed pitch-shifted signal.

Hold control mode is accessible on the rear panel. This is used to select between toggle On/Off button and momentary button modes.


HOLD SAVER ON: After Un-Bypassing FX, the Hold signal is resumed
HOLD SAVER OFF: After Un-Bypassing FX, the Hold signal is reset

FILTER SECTION

FREQUENCY: Cutoff frequency of the selected filter mode. Frequency range 60 Hz … 20 kHz

RESONANCE: Resonant peak at cutoff frequency

FILTER ROUTING: Routing scheme of the filter:

- OFF: Filter section is off. Filter does not affect the Dry or Wet signal.

- MAIN: Wet signal routed to the Filter. Filter does not affect the Dry signal.

- POST: Wet and Dry signal routed to the Filter.

FILTER MODE: Selectable filter modes:

- LPX: LowPass filter mode (24 dB/oct) 

- HPX: HighPass filter mode (12 dB/oct) 

- BPX: BandPass filter mode (6 dB/oct) 

- XAU: Wah-Wah filter mode


SPECIAL FILTER MODE

In Special mode, the filter is controlled by either the Left or Right Pitch-Shifter parameter. From here it is possible to vary filter modes and routings. This allows emulation of Tape-Stop or Tape-Play effects.
LEFT CHANNEL SYNC: The Filter Frequency parameter is controlled by LEFT PITCH
SHIFTER, which works as SUM (Filter+Left Pitch Shifter).
The RIGHT channel continues to work as a simple Right channel Pitch Shifter

RIGHT CHANNEL SYNC: Filter Frequency parameter is controlled by RIGHT PITCH
SHIFTER, which works as SUM (Filter+ Right Pitch Shifter).
The LEFT channel continues to work as a simple Left channel Pitch Shifter

CLOSE: The close button returns the filter section to normal operation, disabling Special filter mode

MAIN SECTION

PLACEMENT: Placement (Mix) between Dry / Wet signals

DRY: Gain of the Dry input level (unprocessed input signal)

WET: Gain of the Wet input level (unprocessed input signal)

SOFT BYPASS: Bypass with fade in and out to exclude loud peaks when the effect is enabled or disabled.

Bypassing the effect whilst the Hold function is engaged clears the buffer.
To have active Hold signal after Un-Bypass, Coriolis FX need at the Input any active sound.
If at the unbypassing moment you have the silence at the device input, you have Holded silence sound!
After Un-bypassing FX, Holded sound can be not the same as you hold the signal before, because every new unbypass work like a new Hold process.
