** This app does not sample any PCM-based synths, including Roland or Korg digital keyboards. Additionally, this app does not have any business relationship with Roland, Korg, or any other 80s/90s Digital Synth manufacturers.

*** All app sounds were created by pure analog and fm synthesis. We took these new sounds. Stacked them. Flipped them. And, processed the heck out of ’em. Resulting in a beautiful new sonic palette for you to enjoy.

Great Synth by a Great Company

Not only is the synth itself really amazing, but it does a great job combining an old technology in a new way. Makes really great pads naturally but also can be used for some faster funky stuff too. The AudioKit team is very responsive to bug reports and is committed to fixing everything they can.

This is a great synth but also realize all the proceeds go to supporting the open source effort of AudioKit. They make free synths for everyone and they provide a free platform to help people make their own audio applications to their apps. I’d get the synth just to support that effort, but it also happens that this is a very nice one of a kind synth for iOS.

Sweet incredible retrotastic glory!

This synthesizer is perfect. The controls are laid out intuitively, the occasionally self deprecating commentary is… Well, we are all right there with you, little synthesizer. And the sounds! It’s like a guided tour of what the ‘90s were trying to be. An encapsulated anachronism tuned for the modern ear. Incredible. Useful. Perfect.

This app is dramatically underpriced. I don’t know what the regular price will be after launch, but for five bucks I feel like I stole this. It would be a deal at $50. If they make this as a plug-in for Logic, hopefully they’ll charge a more reasonable, and much higher, price. (Note to devs: PLEASE DO THIS.)

Simple, Smart, and Sophisticated Synthesis

The Audio Kit team has taken the best from their other development projects and created a refreshing take on the classic D-50 synth.

While I’ve been doing sound design for more than 30 years, and feel comfortable tackling a steep learning curve, this system allows for quick and easy exploration of the system, and the creation of both classic and surprisingly fresh sounds with shocking rapidity.

The expansive modulation matrix, brilliant filter models, and a vast array of sampled sounds, allows for a seemingly endless range of tonal possibilities, and that’s before you discover the standard waveforms.

I had the good fortune, and good sense, to purchase this app on launch day, and at a fantastic discount, but it is well worth the full price. I’ll be using this system for a long time to come.
