  • 32-bit floating-point signal processing

Built-in Modules:

  • Virtual Analog Oscillator (4 classic waveforms)
  • ADSR Envelope
  • Noise Generator
  • Mathematical Modules: Addition, Multiplication, Subtraction, Sine, Modulo
  • Random Number Generator
  • MIDI controlled Keyboard

  1. Just curious, but why is iOS6 required? That kills us first gen iPad owners. I get that it’s an older OS but there are supported apps that have a lot more going on, is there no work around for buffer issues? But on the other side of that I will be eagerly awaiting an iPhone version, as long as my 4s can handle it…

    • I used one feature from iOS 6 which cut my development time significantly (it helped me build the patch browser quickly). I might re-implement that feature myself for iOS 5 compatibility, but no guarantees. I’m also concerned about performance on iPad 1. In particular, Audulus uses the GPU a lot more than most synths.

      • Aw, crap. I wish I had read that before I bought it! Oh well, great to see the app on the platform, none the less.

          • If one tries to buy an unsupported app from their iPhone or iPad it won’t allow it. Buying from iTunes does not have the same restriction. It will let you buy any app regardless of what devices you may own. (And really, that’s how it should work)

  2. Bought. No clue when I’m going to have time to play with it, but I support this kind of thing!

  4. Totally awesome! This is a new level of power and control of a synth on the iPad. So many possibilities :-)

  5. This app has matured well on the Mac so it’s great to finally see it on the iPad it’s almost exactly the same on the iPad and you can share patches between the two. It works well, sounds great, and has a much more straight forward interface than Jasuto. Once Taylor gets Audiobus and copy/paste added this will be killer.
