INFO
Information about the library and version number.
Choosing articulations and sounds

Use these switches to choose which sound you want to play.
On some instruments there are 2 or 3 pages of sounds. Use the arrows and numbers to access these additional pages.
Hold down SHIFT on your keyboard to select or deselect more than one to play them 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.
Episodes

What are Episodes?
Episodes is our new features where the vocalists each sing a specific vocal harmony which works in both key and tempo.
The Sopranos, Altos and Tenors all their own specific Episode in each of their individual NKIs if you want to break out the parts. The Basses do not have an Episode.
However we’d suggest the Ensemble NKI is your best place to start with the Episodes and the one where you’ll have most fun.
The Episodes are very long performances, but do not loop. If you want to hear more of the same Episode, simply the play the note again.
- Choose the key your are currently working in from the KEY selector e.g. D Minor
- The green keys represent the Episodes and on these keys you will here a specifically recorded harmony that will work across the whole key you have selected. It will also work with the other section’s Episodes.
- The Blue keys are normal improvised notes which are a sustained notes.
TEMPO SYNCING
The Episodes were performed at 105bpm, and you can either maintain that tempo regardless of what your DAW is set to, or you can tempo-sync it to your DAW’s tempo. Bare in mind the further you get away from 105bpm, the more stretched the samples will become.
Under the EDIT panel of the Episodes articulation switch you can choose between:
Tempo Sync OFF – The Episodes will play back at their recorded 105BPM
Tempo Sync ON – The Episodes will play in time with your DAW’s tempo.
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 are set by default to be controlled via velocity so this fader will have zero effect.
LEG – LEGATO (Legato articulations only)
Changes the speed of the legato transitions between notes. At the minimum position you will hear the most transition but there will be a slight delay (200ms) before the next note is heard. Maximum position has almost zero delay but the transitions will be quite blurry and not very realistic. We’d suggest using this setting for playing/recording live.
VOW – VOWEL (Certain articulations only)
Controls the vowel sounds specific articulations.
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. There is no microphone section in the Textures.
MIX
A production-ready mix, created from the main microphone signals. Whilst you can add other signals to this mix, you may introduce some phasing as you’re using two versions of the same signal.
CLOSE
This mic is the driest and you will hear lots of details from the singers. These micc are pre-panned, so you will hear the vocalists further to each side of the stereo field depending on where they were placed in the studio..
ROOM
A balanced and open position.
GALLERY
A high up and diffuse position to capture the natural reverb tail of the studio.
—
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

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.
Please note the available settings will be different or not available depending on on what articulation or sound you are editing.
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 PRESETS
3 distinct EQ presets;
FLAT – An uncoloured neutral setting.
AIR – A cut to the lower mid range to help reduce any muddy build-up, with a subtle ultra-high boost to create a sheen.
GRIT – Warm tape saturation with a gentle lift in bass response.
–
SPEAKER CAB Not pictured (TEXTURES only)
A 2×12 speaker cab emulation. Use to add a bigger sense of space.
SIZE
Changes the size of the cabinet. A larger cabinet will have an increase in bass response.
AIR
Changes the early reflections and will add a sense of space and depth.
BASS/TREB
Cut or boost the Bass & Treble.
–
LOFI Not pictured (TEXTURES only)
A classic bit crusher with controls for BITS to control bit-depth and S-RATE which controls sample rate.
–
CRUNCH Not pictured (TEXTURES only)
A gritty tube distortion with controls for DRIVE to control the level of distortion and DAMP which reduces the higher frequencies added to the effect.
–
CHORUS Not pictured (TEXTURES only)
RATE
Adjusts the speed of modulation, from slow pitch changes to fast vibratos. This becomes more pronounced as AMOUNT is increased.
AMOUNT
Adjust the overall amount of the modulation applied to the effect.
FEEDBACK
Adjusts the level of the feedback signals creating a more sustained and spacious sound.
MIX
Blends between the dry and wet signal.
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.
–
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.
Textures

A specific synth version of our EVERGREEN framework, here you’ll learn about the controls for the Textures Instrument.
EXP
Overall volume for the instrument. Controlled via CC11.
–
GLIDE
A portamento effect which smoothly glissandos between different notes.
SPEED
Adjust how quickly it takes to glide between notes.
R – RELATIVE
OFF – Takes the same time to glide between notes regardless of their interval.
ON – The speed is relative between notes. Bigger intervals will take longer. Smaller intervals will be quicker.
MODE
MONO – You can only play one note at a time.
POLY – You can play multiple notes. The glide will occur between the last note played and the new note.
–
VOLUME & PITCH LFO
Two LFOs used to inject motion into the sound.
SPEED
Change the speed of the LFO.
SYNC (Note switch)
ON – Synchronises to the tempo in your DAW. The speed knob will set the note value.
OFF – Sets the speed on milliseconds.
DEPTH
Sets the depth of the LFO.
–
FILTER
A low-pass filter with a medium cut-off slope.
FREQUENCY
Change the cutoff frequency of the low-pass filter.
V (VELOCITY)
When turned ON, note velocity will set the filter cutoff. Higher velocities will open the filter up more. The Frequency knob sets the where the cutoff starts at the lowest velocity.
RESONANCE
Sets the resonance of the filter.
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
