Primer is a synth equipped with the most essential controls and nothing more. Created by Audible Genius, it is an exact replica of the synth used in their award-winning synthesizer training app, Syntorial. As such, Primer contains the most common controls found on most subtractive/analogue synths, allowing for a wide variety of patches and sounds, while presenting a simple and easy-to-understand interface and layout.

Included with the Primer app is the AUV3 App Extension, allowing you to open multiple instances of Primer inside popular DAW apps like Garageband, Cubasis, and AudioBus.

Deceptively powerful

Under the guise of being a “beginners’” digital synthesis application, it is far more than that. It’s a good ol’ fashioned 2-oscillator synthesizer with effects, but also has a nice unison expander with 2 or 4 voices. Flexible and powerful, it nicely compliments my temporary my-last-computer-basically-exploded-so-I’m-trying-to-produce-an-album-on-my-ipad-while-I-wait-to-buy-a-new-computer GarageBand workflow. It fills the gap the GarageBand has of not having an actual honest-to-goodness synthesizer.

Purchased my Minimoog in 1973

I have been writing, composing, playing, recording and have 4 albums out globally. One more album to be released in May and another in June. I am only saying this because I have been playing synthesizers for 47 years. This synth isn’t just for beginners, although it’s a great one to use for that purpose. I love it. I am writing my own presets, but the factory presets are great. Nice gift to have and nothing negative to say about it. Thank you!
