This is going to be a really big deal. AudioKit Synth One is coming soon from the people who brought you FM Player: Classic DX Synths. If you don’t know who I’m talking about, AudioKit Pro, is an open source framework for building iOS synth and audio applications. It’s actually pretty amazing and totally powered by passionate and talented individuals who want to make incredible apps. AudioKit doesn’t just power iOS apps though, it can be used for macOS and watchOS apps too, so it’s a pretty versatile framework.

It’s worth taking a look at the many apps that are powered by AudioKit. You’ll be surprised by the number and range of apps that make use of the framework, and of course they’ve made their own creations too.

Their latest app has been some two years in the making and is the first free and completely open source synth on iOS. That in itself is a very impressive statement. However, when you look at the app and the functionality that’s packed into it, you’re going to be even more impressed.

Here’s what you can expect:

  • Hybrid Analog/FM Poly Synthesizer
  • Over 200+ Presets crafted by famous sound designers
  • Audiobus 3 & Inter-app Audio (IAA)
  • Five Oscillators (2 DCO, FM, Sub, Noise)
  • 2 Assignable LFOs with dozens of routing possibilities
  • 100+ Alternative Scales & Tunings
  • Vintage-Style 16-Step Sequencer
  • Classic poly arpeggiator
  • MIDI in (Control with a MIDI Keyboard or DAW)
  • Touchable ADSR Envelopes for Amp & Filter
  • FM Oscillator w/ Mod
  • Dedicated Sine/Square -12/24 Sub Osc
  • 4-Pole Vintage Low-Pass Filter
  • High-Pass/Band Pass Filters
  • Mono portamento & legato
  • Beautiful Sean Costello Reverb
  • Multi-tap (ping-pong) delay
  • TouchPads
  • Preset Import/Export & Moreā€¦
  • MIDI Learn on all knobs, MIDI Bank/Patch & Sustain Pedal support
  • Full Source code included

It’s an impressive list, and it’s going to be an impressive synth. What’s more even after they’ve delivered version 1 they’ve got a bunch of updates already in the pipeline to make it better still.

Today you can read about AudioKit Synth One here, and sign up at AudioKit. Tomorrow there’ll be more news, and you can expect the app to land at an app store new you in around 2-3 weeks. Personally, I can’t wait. It’s a big step forward for mobile music, for the community, and for AudioKit Pro.

If you really can’t wait that long, you can always grab their current app FM Player to give you a feel for what’s coming, and of course, you can sign up to get email news about the app when it lands. Expect to find it here too when it arrives.

For now, check the video, and enjoy.
