This is it. The first full-fledged synthesizer available for the iPhone.
Noise.io Pro features everything you would expect from a synth including a large and expandable preset bank, a powerful sequencer, a rich ESFM synthesizer processor, (an enhanced version of the traditional Frequency Modulation) along with all the bells and whistles you can expect from any professional synths. Also included are two different input methods, a standard 2-octave keyboard and a cell-based system similar to the legendary Kaoss Pads from Korg.
Most hasty iPhone users would've probably downloaded the app without finishing the article, and for the most part, they will be disappointed. Not by any flaws in the application, which in itself is a perfect balance of stability and performance, but because Noise.io Pro requires quite a bit of experience and know-how in the field of electronic music production to be put to good use.
One of the few quirks I did have with this app was the broken/missing recording feature. Not to worry, the creators have stated that they plan to integrate the option in the near future through updates.
Download Noise.io Pro today from the App Store and remember, it's strictly for professionals.
