Arctic Keys is a virtual analog synthesizer. With a classic dual-oscillator subtractive synthesis design that gives you the sound creation flexibility we all know and love. With an easy to use user interface that just wants to be tweaked. The result is a truly professional instrument with an audio quality that rivals that of hardware synthesizers.


With all the synthesizer parameters immediately available on one page, you get instant feedback as you tweak. The two LFOs each have three modulation destinations. Each LFO may also be free running or sync'ed to tempo and the timing rate adjusted. The modulation matrix allows for deep routing between the Mod Wheel, aftertouch and 16 x 4 analog-style gated step-sequencer. Quickly change pages to edit effects and sequences.


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 4 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 aftertouch.


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's 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, e-mail the patches you make, then open them directly and save into your patch library. Or share them with Wi-Fi and iTunes File Sharing.

A new appraisal - I've come out of the cold


Just reloaded this again onto my iPhone and what a pleasant surprise. I originally wrote this quite a while ago:'The library of voices are terrible, not only do none of the voices imitating instruments are nothing like the original instruments but the bass, sound fx and pads are also quite feeble.'
There seems to have been some serious work on this synth app, so well done for that. I actually rather like Arctic Keys now. One thing that blew me away was the astonishing nine and a half octave range (beyond the limits of audibility both at the bottom and the top). Going to have some fun now playing with this. If only I could use it with my Akai Synthstation 25; that would really open it up for me. So, overall a great improvement. 4 stars!



Works well, the controls all make sense and the range of sounds you can create is limitless..
If you have any experience of old analogue synths you will really love the familiar controls.
If you are new to synths I'm sure you will enjoy making all sorts of noises and before long this app's clear controls will help you get to grips with it and turn you into a true artist in the field of sound sculpture... Well done.

There are other big brand synth apps out there but they have a steep learning curve to get through..this app is just so easy to get in, get on and get making sounds with...

I'm sure there are more features I've yet to try (and learn) but so good

Keeps crashing


I want to like this synth but it keeps crashing on my ipad1. I've rebooted my iPad to clear the memory and it still keeps doing it. Other apps are rock solid.
Edit: The dev knows about the issue and a fix is on it's way. Thanks for the fast response.
I'll update to 5 stars when the fix is in place.
