INTRODUCTION
INTRODUCTION
Thank you for purchasing Arctic Keys for iPad. Arctic Keys is a virtual analogue
synthesizer for iPad that delivers audio quality equivalent to that of high cost hardware
synthesizers. Featuring a classic dual-oscillator subtractive synthesis design that gives
you sound creation flexibility, with an easy to use user interface that just wants to be
tweaked.
Tweak. With all the synthesizer parameters immediately available on one page, you get
instant feedback as you tweak. The two low frequency oscillators (LFOs) each have
three modulation destinations. Each LFO may be free running or synched to tempo and
the timing rate adjusted. The modulation matrix allows for deep routing between the
Mod Wheel, after-touch and 16 x 4 analogue-style gated step-sequencer. Quickly
change pages to edit effects and sequences.
Perform. The classic arpeggiator is complimented by the 16 x 4 gated step-sequencer.
Play a note to trigger the sequencer. Step through a sequence to play short melodic
lines or let it modulate the synthesizer. The different key gating options may be used to
change how the sequence is triggered. Each of the four tracks has an assignable
modulation destination and loop point. Along with traditional Pitch and Mod Wheels,
adjust the velocity by tapping along the length of the key from top to bottom. Change the
key mode to mono for retro lead lines. Adjust the size of the keyboard to suite your style
or use a gesture to scroll through the octaves. Place the keyboard into Pitch mode and
use multi-touch gestures to bend individual notes, while sliding up and down the keys to
add after-touch.
Share. The live phrase recorder lets you save your performances as 44.1KHz 16-bit
WAV files and as a Standard MIDI File. The MIDI File includes all the knob control
change information along with the notes you play. Use Sonoma AudioCopy or Intua
Audio Sharing to paste recorded audio directly into other apps. From within Arctic Keys,
email the patches you make, then open them directly and save into your patch library or
share them with Wi-Fi and iTunes File Sharing.

Keyboard
KEYBOARD
The keyboard is split into three areas: the piano keys, a strip of control buttons and the
pitch and modulation wheels.
KEYBOARD CONTROL
[-] octave down
[+] octave up
[PLAY MODE] adjust the play mode: poly, mono, legato, unison, arp, seq
[UNISON] enable the unison mode which stacks all voices on to the one key
[HOLD] keep the pressed key held down
[SIZE] adjust the size of the keys: small, medium, large
[KEY MODE] adjust the key mode: glissando, scroll, pitch
[SCALE] enable the keyboard’s scales mode
[PANIC] send an all notes off message to turn all sound off
PLAY MODES
POLY
This mode allows you to play chords.
MONO
This makes the instrument monophonic. If you press a key without releasing the
previous one the envelopes are still retriggered.
9
Keyboard
LEGATO
This mode also makes the instrument monophonic but if you press a key without
releasing the previous one, the pitch change and the envelopes are not retriggered.
UNISON
When this mode is active all four voices will be played when you press a key. The
instrument is monophonic.
ARP
This mode enables the arpeggiator. When active pressing a key will initiate the selected
ARP pattern to being (ARP pattern is set fro the FX screen, see page 24). Releasing the
key will end the pattern, unless the HOLD keyboard mode is active.
SEQ
This mode enables the sequencer. When active pressing a key will initiate the pattern
set in the step sequencer. Sequences are created in the SEQ screen, page 26.
KEY MODES
GLISSANDO
In this mode tapping the piano keys will cause them to trigger. Sliding your finger around
the keyboard will cause each individual note to play. Tapping at the top of the key
(nearer the strip of control buttons), will strike the key softly. Tapping at the bottom of
the key, will strike the key harder.
SCROLL
Same as glissando except sliding your finger left and right will also adjust the current
octave.
10
Keyboard
PITCH
Same as glissando except sliding your finger left or right after the note has been
pressed will adjust that notes pitch. Sliding your finder up and down on a pressed note
will adjust that notes aftertouch.
SCALES MODE
When enabled the regular black and white piano keys are replaced with a set of white
only keys. Only the notes in the scale are playable. The root note of the scale is shown
in a darker colour and the note name is printed on the key as a reminder. The scale can
be set from the musical note button in the keyboard control bar.
Within the [PREF.] menu, there is a sub-menu setting called “Key” that allows the root
note of the scale to be set. Major and minor scales may also be selected from this
menu.
The piano keyboard will send only MIDI notes from the selected scale. The current scale
does not restrict incoming MIDI note messages.
11
Keyboard
PITCH AND MODULATION WHEELS
PITCH WHEEL
The pitch wheel is used to bend the notes just as with a pitch bend wheel on traditional
synthesizers. Hold your finger on the wheel and slide up and down. Lifting your finger off
the wheel will spring it back to the centre position.
The pitch wheel is used to raise or lower the frequency (pitch) of a note and is modelled
to behave like the pitch bend wheel on traditional synthesizers. Hold your finger on the
wheel and slide up or down to alter pitch. Lifting your finger causes the wheel to spring
back into centre position.
MODULATION WHEEL
Tap and hold the modulation wheel, then slide you finger up and down to adjust the
value. The effect of moving the modulation wheel can be different for each patch. To
adjust what parameter the wheel modulates, tap the blue [MOD] button above the
wheel. From the menu, select an appropriate parameter. The default modulation routing
is set to Filter Cutoff.
12
Keyboard
XY PADS
The XY Pads comprise of two regions from which it is possible to adjust the
synthesizer’s parameters. They resemble a mouse touch pad commonly found on
laptop computers. Sliding your finger left and right changes the value assigned to the xaxis, while sliding up and down changes the value assigned to the y-axis.
The left hand XY Pad in light blue has the x-axis fixed to pitch while the y-axis may be
assigned to any modulation source. Tapping the name of the modulation source will
present a menu from which to select the sourc. The x-axis pitch control is sprung and
will always return to the central position when you lift your finger.
The right hand XY Pad in yellow permits both the x and y-axes to be assigned to any
modulation source.
Double tapping either pad will return the control to the central position.
13
SYNTHESIZER
SYNTHESIZER
Arctic Keys is a subtractive synthesizer, one of the oldest and most widely used forms
of synthesizing sounds. It is the same method employed by classic synthesizers such
as the Moog MiniMoog, Korg PolySix, Dave Smith Prophet’08 and Evolver, and the
Clavia Nord Lead.
The block diagram on the next page shows the building blocks of the synthesizer,
consisting of the oscillator (VCO), filter (VCF) and amplifier (VCA).
Sound has three basic elements: pitch, timbre (or tonal character) and volume. Like the
aforementioned classic synthesizers, Arctic Keys provides a digital emulation or virtual
collection of these analogue components. In a subtractive synthesizer the oscillator or
VCO is the only section that actually produces any sound. Edit the VCO to modify the
pitch, the VCF to modify the timbre, and the VCA to modify the volume.
In addition to these three core components, Arctic Keys includes several modulation
sources: devices that can continuously vary volume, timbre and other qualities of the
sound over time when you play a key. These modulators add movement to the sound to
make it more interesting.
The three modulators are Envelope Generators (EG), LFO and Sequencer.
The envelope generators are used to shape the sound. When applied to the amplifier
(which controls the volume) we are able to make the sound slowly fade in and then fade
out as you press and hold a key.
The LFOs, or Low Frequency Oscillators, are used for repeating variations in the sound,
such as adding tremolo or vibrato.
The Sequencer is a step sequencer that can be used for short melodic lines and to
modulate the sound.

SYNTHESIZER
OSCILLATORS / VCO
The synthesizer uses two oscillators to generate sound. These are often referred to as
the VCO. In a true analogue synthesizer a voltage is used to control the pitch of the
oscillator. This pitch signal typically comes from playing the keyboard. In a virtual
analogue synthesizer this effect is digitally modelled.
OSCILLATOR 1
[WAVE] select the oscillator waveform: sawtooth, square or triangle
PULSE WIDTH controls the width of the waveform
SEMITONE controls the tuning of the oscillator
ENV MOD controls the amount by which the envelope modulates the oscillator
16
SYNTHESIZER
OSCILLATOR 2
[WAVE] select the oscillator waveform: sawtooth, square or triangle
PULSE WIDTH controls the width of the waveform
SEMITONE controls the tuning of the oscillator
ENV MOD controls the amount by which the envelope modulates the oscillator
DETUNE finer control oscillator pitch
[SYNC] slaving OSC2 to OSC1 forces the wave-cycle of OSC2 to restart when the
wave-cycle of OSC1 starts
17
SYNTHESIZER
MIXER
The mixer is used to combine the output from both oscillators.
OSC MIX controls the balance of each oscillator output
OSC VOLUME controls the overall level of the oscillator output, including a clip light
RING MOD controls the amount by which each oscillator is multiplied
NOISE controls the level of the noise generator
18
SYNTHESIZER
FILTER / VCF
[MODE] select the filter mode: low-pass, high-pass, band-pass, notch
[SLOPE] select the roll-off -12dB (2-pole), -24dB (4-pole)
[ENV MOD] adjust the amount by which the envelope modulates the filter cutoff
frequency
CUTOFF adjust the frequency at which the filter starts cutting. If the cutoff frequency in
a low-pass filter is set to a very low value, only the lowest harmonics (bass) will pass
through
RESONANCE adjust the Q or emphasis of the frequencies around the cutoff point
KEY FOLLOW adjust the amount by which the filter tracks the keyboard
ENVELOPE the four sliders set the attack, decay, sustain and release curve of the
envelope generator
[CURVE] adjust the slope of interpolation between each stage in the envelope. A linear
curve is a straight line between each point, whereas adding more curvature produces a
rounder line or scoop

pitch starting during the current note, finishing on the moment the next note begins
SLIDE CURVE adjust the curvature of the slide from linear to exponential
22
EFFECTS
EFFECTS
Arctic Keys includes four final stage effects that are connected in series. This is akin to
having a row of four guitar effect pedals connected one after the other. The input signal
is taken as the output from the synthesizer amplifier (VCA). The effects are: EQ,
Distortion, Chorus and Stereo Delay. The order cannot be modified.
3-BAND EQ
[ACTIVE] enable or disable the effect
HIGH controls level of high range band
MID controls the level of the mid-range band
LOW controls the level of the low range band

[OCT] adjust the octave range of the notes
[MODE] adjust the order in which the held notes are played
UP plays from lowest to highest note
DOWN plays from highest to lowest note
UP/DOWN plays from lowest to highest and back to lowest
ASSIGN plays notes in the order the keys were pressed
RANDOM plays notes randomly
SHUFFLE adjusts the timing shuffle or swing between each note
[CLOCK DIVIDE] set the timing division
27
The sequencer and the arpeggiator share the same BPM settings. The tempo is set
from the [PREF.] menu.
To activate and play the arpeggiator the KEY MODE must be set to ARP.
The arpeggiator does not schedule and transmit MIDI note data.
Note: If the arpeggiator does not seem to be working, check the MIDI settings to
ensure that External Sync is OFF. If External Sync is set to ON the arpeggiator
uses an external clock source and Arctic Keys must be receiving MIDI clock
messages in order for the arpeggiator to run.
28
Sequencer
SEQUENCER
The Arctic Key’s sequencer is more like an original analogue sequencer than the
familiar computer based MIDI sequencers. The sequencer comprises four 16-step
sequences or tracks that play in parallel. Each track can be routed to a different
destination and each step in the sequence can be set to a different value. These values
are then used to modulate the chosen destination. Like the arpeggiator, there is one
sequencer that applies to all voices.
Note that the sequencer does not actually schedule MIDI data, nor does it transmit MIDI
data. A sequence is a series of events at timed intervals that changes the value of one
of the synth’s parameters in fixed steps. As the four tracks play in parallel, up to four
parameters may be changed by each step. This also means that chord based melodies
can be sequenced. The sequencer does not have to include note or pitch events. With
no note events present, the sequencer can modulate only the synth’s parameters.
The Arctic Key’s sequencer is a gated sequence; it requires a note on message to be
gated and start running. This may come from the piano keyboard or from an external
MIDI source. The pitch of this note is used to transpose the pitch of any sequenced
notes. A note value at middle-C (MIDI note 60) will pitch the sequencer at zero and
ensure any melodic lines play as programmed. A note value higher than middle-C will
transpose up, while one lower will transpose down.
The sequence duration is set by the BPM tempo and clock divide settings, or MIDI clock
if synced to an external clock source.
The user interface is split into the following areas:
STEP these comprise the 16-step buttons running across the top of the display
VALUE the 16 value sliders for each step
29
Sequencer
SEQ setup menu to adjust each track’s destination
FWD skip forward a step when in record mode
SHUFFLE adjust the amount of shuffle or swing in the sequence timing
TRACK these are the buttons numbered 1 to 4 and are used to select each track
The step buttons have a number of different modes of operation that can be cycled
through by tapping the button several times.
OFF button is black and step value is skipped
RED record mode, when you press a piano key the step value is entered based on the
note value
BLUE step is on
GREEN repeat, track is set to the first value
Ensure that there is no RED step button when playing back the sequencer.
To change the value at each step, slider your finger up and down the value bar.
The sequencer and the arpeggiator share the same BPM settings.
To activate and play the sequencer the KEY MODE must be set to SEQ.
The sequencer does not schedule and transmit MIDI note data.
Note: If the sequencer does not seem to be working, check the MIDI settings to
ensure that External Sync is OFF. If External Sync is set to ON the sequencer
uses an external clock source and Arctic Keys must be receiving MIDI clock
messages in order for the sequencer to run.
30
PATCH BROWSER
PATCH BROWSER
The Patch Browser is used to load individual sound settings and access the file sharing
options.
The Patch Browser is split into to two sections: Patch Categories and Exports. The
larger table shows the available patches and files. The toolbar at the bottom of this table
is used to edit, delete and share the patch or file.
31
PATCH BROWSER
PATCH CATEGORY
The content of each category is set by the value of the Tags field.
Using the toolbar individual patches may be edited and deleted. When editing the name,
author and tag information may be changed.
Patches can be sent through email or saved into the Documents folder and accessed
via iTunes File Share. They will also then appear in the Exports Presets area.
To load a patch, simply select it in the table. The OK and Close buttons are used to exit
the Patch Browser and return to the main synthesizer interface. The patch is then ready
to use. The Cancel button will exit the Patch Browser and re-load the patch that was in
use when the Patch Browser was opened. The Keys button shows the piano keyboard
and allows for easy previewing of patches while the Patch Browser is active.
MIDI BANKS
The MIDI Banks section is used to organise the patches by bank and program. These
can then be selected with MIDI Bank Select and Program Change messages. There are
8 banks each with 128 patches.
A patch may appear in multiple banks and may be duplicated in any slot, allowing for
patches to be arranged for live performance and so on.
The patch banks store a reference to the patch, so any edits to the patch will be
reflected in all MIDI Bank locations.
EXPORTS
The Exports section shows files that are stored in the application’s Documents folder.
Items in this folder are also available when using iTunes File Sharing.
Presets may be imported into your local patch database.
Audio files may be shared in several different ways: via Sonoma AudioCopy, exported
to and opened by another application on the iPad, or sent via email. They may also be
uploaded to a SoundCloud account.
The Wi-Fi Transfer allows you to access the files in the Documents folder from a web
browser on another computer, such as Safari on a Mac. When activated, the required
web address is displayed and this should be entered into Safari’s (or IE, Firefox etc)
address bar. Note that Wi-Fi Transfer uses port 8080. Ensure that this port is open in
the firewall on the computer running the web browser.
32
MIDI IMPLEMENTATION
Note. If your iPad is connected to a Wi-Fi access point in infrastructure mode, it
may be necessary to disable Wireless Isolation. If enabled, Wireless Isolation will
hide devices on the same Wi-Fi network from each other, and they will not be
able to communicate with each other. Refer to your Wi-Fi router’s user manual for
more information regarding Wireless Isolation and firewall settings.
MIDI IMPLEMENTATION
Arctic Keys supports CoreMIDI networking over Wi-Fi and a USB MIDI interface
connected to the iPad with the Camera Connection Kit.
To see the list of currently available MIDI devices that Arctic Keys will use:
1. On the toolbar at the top of the screen, tap [MIDI].
2. A list of available MIDI devices will be shown.
Arctic Keys will send and receive MIDI messages on any of the hardware devices listed.
If you are using a supported USB MIDI interface, it will be shown in this menu.
MIDI LEARN
Using MIDI Learn, Arctic Keys can map incoming MIDI CC messages to specific
synthesizer parameters. However, note that Arctic Keys does not transmit MIDI CC
messages. Instead higher resolution 14-bit MIDI NRPN messages are transmitted.
These messages may also be used to externally control the synthesizer and are saved
into the MIDI File produced by the live phrase recorder.
LOCAL CONTROL
This option is used for turning local control on or off. The default setting is ON. When
local control is OFF, Arctic Keys will not trigger internal sounds when using the piano
keyboard. Arctic Keys will only make sounds when triggered by incoming MIDI data.
However, MIDI data is still sent out.
EXTERNAL SYNC
This option is used to enable or disable external synchronisation. When set to ON,
Arctic Keys will respond to MIDI Clock messages and synchronise the arpeggiator and
sequencer to this clock and tempo. The recorder and transport controls are disabled
33
MIDI IMPLEMENTATION
when external sync is ON. The default setting is OFF.
KORG WIRELESS SYNC-START
Arctic Keys supports Korg Wireless Sync-Start (WIST) when used in combination with
two iPad’s running compatible apps (refer to the Korg About WIST website for a list of
available apps http://www.korguser.net/wist/).
•
•
•
The iPad that controls play/stop is called MASTER. The other iPad that is
controlled by the MASTER is called the SLAVE
Tempo value in MASTER is automatically set in SLAVE at play start
Bluetooth is required. No Wi-Fi is required.
How to use:
•
•
34
When Arctic Keys is the SLAVE, only the tempo setting in the [PREF.] menu is
changed
When Arctic Keys is the MASTER, play/start is sent only when a key is pressed
in Sequencer mode
