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.

Have had arctic keys for a while. I initially played with it and then stopped because I didn't want to put very much effort into learning how to use it and the presets were kinda boring. However, I learned how to use the sequencer and then the update with iPhone support, scales, and x-y control came out and it blew my mind. Try putting the synth in scale mode, put the setting for the keyboard on pitch, and slide up and down vertically to control parameters of the synth, such as cutoff, while tweaking the x-y pads and you will start to really fall in love with it like I did.

Review revision

Okay my initial review was a bit harsh so I am rewriting it as I do believe in this developer, and I have spent more time with the app. So that said this is a pretty darn nice synth, the main OSC can easily be overdriven so if you are not liking the sound you are getting dial back a bit and work from there. Honestly when you open a synth app the same rule applies as if you were walking into a music store. First impressions of the sound quality and presets are huge. They should instantly spark the imagination and with the initial release I felt they were a bit lack luster, but after tweaking them a bit and dialing in the oscillator a bit I a really getting some nice sounds. I am really quite impressed and I am looking forward to further development and new apps!

Another Next-Gen Gem!

Could not disagree more with the "looks good, sounds bad" assessment of an earlier reviewer; it not only sounds good, it has incredible features like it's programmable mod wheel ( multiple, scalable assignments please? So the cutoff & resonance could be contrasted in one go? Just a thought), & an OUTSTANDING arpeggiator/sequencer as well as Audio Copy/Paste implementation. Made an awesome bass line sequence in my first exploratory session with Arctic Synth with no tutorial despite a fairly advanced feature set. Definitely a worthy addition to any iPad synth Toolbox Arsenal.
One critical note; please work on the Ring Mod, it's unworthy of the high quality of the rest of Arctic Synth, and is pitiable. Kept this from being a 5-Star review.
