Here's the newly-released preview video of what's been describe by its developers as the largest free and open-source iOS music project in history - AudioKit Synth One. This is what they have to say about it...
AudioKit Synth One is the first completely free & open-source full-featured professional iOS synthesizer app in history.
Created by volunteers, the app will include MIDI support (play it with a MIDI keyboard or controller), sequencer, vintage-inspired analog filters, expressive arpeggiators, warm analog delays, and, over 200+ presets to get you started!
Plus, it’s completely open-source. Use the code to learn how to build your own synth app or modify the app yourself. Anyone can contribute code & features!
This synthesizer will be completely free, fully functional, and ad-free. It’s the ultimate free iPad music instrument app.
