Overall settings for the instrument.
INFO
Information about the library and version number.
Choosing RHYTHMS and sounds
Use these switches to choose which sound you want to play.
FILTERING RHYTHMS (Rhythms only)
On the 01 Rhythms.nki this filter menu will appear where you can choose which tempo, time signature and feel you would like to access.
Hold shift to selector multiple categories.
AUTO tempo will attempt to detect rhythms that are closest to your DAW’s current tempo.
Hold down SHIFT on your keyboard to select or deselect more than one rhythm or articulation at the same time.
The currently active sound(s) will be shown above the main menu.
Any active sounds will also have white frame around their switch.
Instrument Controls:
Changing expression and dynamics
EXP – EXPRESSION
Controls the overall instrument volume via MIDI CC11. Use this to fine-tune the volume of the performance on-the-fly and also create fades from and to silence.
DYN – DYNAMICS
Controls the natural recorded dynamics of the sound via MIDI CC1. Most commonly mapped to your keyboard’s modwheel.This fader will only work if the sound you have selected is being controlled via MOD in the DYNAMICS section. Short sounds, pianos and drums are set by default to be controlled via velocity so this fader will have zero effect.
DOUBLE – Double Track Mode
Plays two separate rhythms or sounds to give the same effect as a double tracked recording. Use the pan controls to change how extreme the effect is. Engaging the link button, will ensure there is always equal sound across both left and right speakers.
RANGE
Controls the range of the recorded notes.
STD (Standard) – the regular range of the cello that was recorded.
EXT (Extended) – an extended range where the samples have been stretched.
TUNE – TUNING (PERCUSSION only, not pictured)
Controls the tuning of each percussion sound independently of each other. Play the key you wish to change the tuning of and then move this fader up to tune up and down to tune down. To reset: MAC Command + Left click WINDOWS Windows + Left click
Microphone Mixing
Access all the microphone positions
Some instruments have more than the 4 microphones on display! Use the arrows or numbers to access all the microphone/signals.
MIX 1 – Close
An ultra close-up and detailed mix.
MIX 2 – Natural
A great all-round mix suitable for most purposes.
MIX 3 – Hyped
More grit, compression and bite. Not too over the top, but a great start if you need the cello to cut through a loud mix.
MIX 4 – Ambient
This mix sounds like you’re outside the studio and listening in.
—
MIC – Spot
A mono position that’s super dry and super detailed.
MIC – Close
This stereo pair is still very close but with bit more space to breathe.
MIC – Room
An XY stereo pair with plenty of natural acoustics. Can easily collapse to mono if needed.
MIC – Ambient
A mic placed in the hallway outside the studio, whilst the studio door was left open. A very distant perspective.
—
POWER SWITCHES
Turns the channel on or off. This also purges these samples from memory.
PAN
The centre position is how the microphone was recorded and intended to be used, but you can pan each channel independently for creative purposes.
FADERS
Changes the level of each channel. The default position is 0dB and the maximum is +6dB.
SOLO / MUTE
Solo or mute each channel. You can also use the SHIFT key to independently solo a channel and remove any other channels from solo.
SAVE & LOAD A MIX
Use the save and load icons to save a favourite mix and re-use it in a different session.
Editing articulations and sounds
Please note the available settings will be different or not available depending on on what articulation or sound you are editing.
Editing sounds and articulations
All sounds have several options that can be edited.
Each sound can all be edited independently of each other, so you can adjust them exactly to your preference without affecting the others.
How to open and close the edit panel
Any active sound will have an edit icon in the top right of its switch. Click this to open or close the edit panel.
Close the edit window using the ‘X’ button in the top left of the edit panel.
Once a sound is in edit mode, you will see an orange box around its switch to confirm which sound you are editing.
DYNAMICS
This setting changes how different dynamic layers are played. By default each sound/articulation is set to its most natural style.
MODWHEEL – Use your modwheel (MIDI CC1) to change the dynamic level. Use this setting for most continuous sounds like long string sounds.
VELOCITY – Access different dynamic levels by playing harder or softer on your keyboard. Use this setting for percussive and naturally decaying sounds like Pianos and short strings sounds.
MOD+VEL – Use your modwheel (MIDI CC1) to change the overall dynamic level. Velocity will have a small impact on the individual volume of each note. This is ideal for long string sounds where you’re playing chords and would like different notes to be softer or louder.
–
SOUND
Not all of these controls are available on every instrument and will be different on certain articulations.
ATTACK – Change the attack time of the sound.
DECAY – Change the decay time of the sound.
SUSTAIN – Change the level sustain.
RELEASE – Change the release time of the sound.
TIGHTNESS – Increasing this control will cut into the start time/transient of the sample. This improves playing responsiveness but reduces realism, as the initial natural sounds at the beginning of the samples are lost.
LEVEL – Changes the level/volume of the individual sound. Use this control to create the desired balance of sounds when you have selected more than one at a time.
PAN – Changes pan position of the sound.
TUNE – Changes the tuning of the sound, up or down 12 semitones. Hold SHIFT for finer increments.
–
ROUND ROBINS
In this section you can control how round robins are controlled. Round robins are different versions of the exactly same sample, recorded to recreate the natural variations in a performance.
When more than one round robin is available for the selected sound, you will see a range of numbers (e.g. 1 2 3 4 5 etc). Under each number is an indicator to show you which round robin is currently being played.
Turn on and off specific round robin samples by clicking the appropriate number. We would typically recommend choosing a number that does not match your time-signature. e.g. when playing in 4/4, choose an odd number of round robins – 3, 5 etc) You can also turn off specific round robins if you do not happen to like the specific sample for any reason.
RESET ON TRANSPORT
Set to ON to reset the playing position of the round robins every time you stop/start playing in your DAW.
CYCLING
Changes the order of round robins are triggered.
CYCLE – Each note will cycle through the order of round robins in sequence
RANDOM – Will randomly play a round robin
FX
TRANSPITCH
Our unique Transpitch control allows you with one click to pitch shift the samples down, whilst transposing them back up by the same amount. TRANSPITCH is not available on all instruments or articulations.
With the samples playing back at a slower speed, this creates a darker and moodier tone. This effect doesn’t respond to all sounds in the same way, so don’t expect everything to feel the same!
Available in 2 semitone intervals, up to a full octave. The higher range of available notes will reduce by the setting you use. e.g. A setting of 6 will remove the top 6 semitones. Using this effect will also add a delay to shorter notes because of the slower playback speed.
–
EQ
A simple wide 3-band EQ. Use the knobs to cut or boost the EQ.
DELAY
A powerful and transformative delay engine that’s capable of a huge range of sounds.
Please note this effect can be quite CPU intensive, so if you are working on an older computer with less power you may notice a dip in performance.
TYPE
Choose one of the 5 delay types: DIGITAL, ANALOGUE, TAPE, VINTAGE and HAZE. They all have their own unique character and sound. The controls will change depending on which delay type is chosen.
BUILT-IN PRESETS
We have created a set of custom presets for the delay engine which you can use to get some instant starting points. Some are more conventional, others are more experimental and unusual.
To access the presets, click the menu switch which will show a pop-up box containing all the presets. Simply click a preset to activate it.
BPM SYNC
Use the ‘Note’ switch to turn on and off synchronisation option. If this switch is turned on (orange), the delay engine will synchronise with the BPM of your composition.
TIME
Set the time of the delay. This control will change depending on how the BPM SYNC switch is set.
If the BPM SYNC switch is turned on, the time can be set in beat divisions including dotted and triplet rhythms and will perfectly synchronise with the tempo set in your DAW. If the BPM SYNC switch is turned off, the engine will default to setting the delay time in milliseconds and will no longer be synchronised.
FEEDBACK
Adjust the amount of signal sent back into the delay engine. Increasing this control will add more intensity to the signal and if pushed to the max will begin to self-oscillate and feedback without more signal being applied.
HIGH CUT
Turn this control down to remove the high frequency content from the delayed signal.
DEPTH (DIGITAL, ANALOGUE AND VINTAGE ONLY)
Adjusts the amount of modulation applied to the delayed signal.
RATE (DIGITAL, ANALOGUE AND VINTAGE ONLY)
Adjusts the speed of the delay time modulation
AGE (TAPE ONLY)
Enhances the characteristics of aging tape.
FLUTTER (TAPE ONLY)
Increases the effect of mechanical imperfections in an old cassette desk
AMOUNT (HAZE ONLY)
Adjusts the amount of Haze applied to the delayed signal creating a washy reverb effect. Higher settings may feel like the effect is out of sync.
SIZE (HAZE ONLY)
Adjusts the size of the delayed signal creating an impression of different sized spaces.
MIX
Controls the final amount of effect mixed into the main output.
Width & Swap Channels
WIDTH
Control the stereo width of the entire instrument. The default position or when this control is turned off, is how the instrument was recorded.
Increasing this control will create a more wrap-around and immersive stereo perspective. Be careful that with certain mixes, the final sound may not translate to mono with this control set too extreme, so ensure you check!
Decreasing this control will push the sound towards the centre and eventually at the minimum setting will create a purely mono signal.
This effect is placed before the DELAY and REVERB effects, so these may further change the stereo field.
A note on WANDERLUST – A few of the sounds for this instrument were recorded in mono (the Prophet 5 is a mono synth!), so the width control will not have any effect if all the other effects are turned off.
–
SWAP CHANNELS
This control can be used to swap the stereo image of the entire instrument. What’s coming out of the left speaker will come out of the right speaker and vice versa.
You can use this to switch how the instrument was recorded, for example from player position to audience perspective. Or for matching other instruments in you composition.
Reverb
Use this built in effect to add a convolution reverb to the master output of the instrument. All the controls to this effect are available on both the HOME page and the FX page.
The power switch turns the effect on and off, and the level knob changes the amount of reverb added to the master signal.
Use the menu to choose one of the 8 completely bespoke reverb impulses we have recorded and created. Designed to give you a spectrum of high quality and very useable spaces to immediately create an inspiring sound.
FIRESIDE – Small, warm and close. Like a cosy living room in the winter.
VINTAGE – An understated small recording hall that is full of character.
COILS – A custom spring reverb we created that’s ideal for that classic sound.
STEEL – A plate reverb that will add natural depth and shine.
STUDIO – Lively and upfront. Created to compliment and augment the natural acoustics of the studio we record in.
HALL – A large, warm hall that’s become one of our favourite reverbs to use on all scores that need a creamy, rich sound.
HORIZON – Dark and moody, this is a 10-second reverb that that feels mysterious and otherworldly.
ECLIPSE – Bright, shimmery and epic. A 20-second reverb that will transform simple sounds into an ambient wash.
Settings Page
On this page you can adjust some global settings of the entire instrument. Not all settings will be available for all instruments.
ALL KEYSWITCHES
You can turn on or off all of the keyswitches here. Do this if the keyswitches clash with any other MIDI information.
KEYSWITCH POSITION
Drag the keyboard icon left or right to change the default position of the keyswitches on the keyboard.
Alternatively use the left and right arrows to shift the selection one note at a time.
Click the keyboard icon to reset to the default position.

AUTO-PURGE MICROPHONES
With this control set to ON, when a microphone fader is moved to the minimum (bottom) position, it will automatically turn off and purge the samples from memory. As soon as the fader is moved, it will reload and turn the channel back on.
If you do not want this behaviour, set this control to OFF.
–
PURGE UNUSED ARTICULATIONS
When the instrument first loads up, it will load all the articulations and sounds into your computer’s memory. This makes it quick and simple to start exploring and playing with all of the sounds.
However if you’re running low on RAM and system resources, you can click the PURGE NOW button to remove any articulation/sound that is not currently selected. Kontakt will then purge these samples from memory and free up the space for other things.
On the HOME page you will see that these switches are now greyed-out. If you wish to reload them, click on any of the sound switches and it will load everything back up again for you to change your selection.
–
KEYBOARD SENSITIVITY
If you external MIDI keyboard has a particular sensitivity bias, you can adjust the response curve of the incoming velocity data here.
LOW will make it easier to play quieter velocities
LINEAR will be make velocities equally playable
HIGH will make it easier to play louder velocities
