Exciting news: After over 3 years of development, AudioKit Synth One is now available as a universal app for the iPhone and iPad. The iPhone version has turned out fantastic: Synth One has been painstakingly handcrafted for the iPhone interface.

HUGE NEWS FOR SYNTHESIZER MUSIC
This is huge news for mobile music-making. Now, anyone with an iPhone can have a full-featured, pro, and portable Synthesizer. The controls and features are all there.

It’s completely free. There are no ads. There’s nothing to buy. The iPhone version doesn’t even require an email address. If you have an iPhone, you can have a synth.
