Ratings and Reviews
Just Keeps Getting Better!
If you have every been interested in modular synthesis or electronic music creation, Audulus is the app for you. Far more than a “soft” synth, Audulus offers a rich visual programming environment for sound creation and manipulation. With a large selection of fundamental building blocks and a wide variety of prebuilt modules including example patches and full synths, Audulus allows you to create almost anything you can imagine. With multichannel IO support, MIDI, IAA and Audiobus compatibility, it can interoperate with other iOS music apps and with a suitable interface can also connect to more traditional hardware synthesizers. It’s available for iOS, macOS and Windows and patches can be shared between platforms. The 3.5 release features a new patch browser integrated with the iOS 11 Files app for simple patch management and sharing. The app has an active user forum where users can share ideas, patches, and assistance and there are several very good tutorials available on the forum to help get you started.
Developer Response ,
Thanks so much HammerDulcimer! Glad to see you're really getting the most out of Audulus - especially the forum :) We have so many great new updates coming along with 3.5, including lots of new patches that were developed first on the forum. Thanks again!
Fantastic learning tool and well-supported
I've had Audulus since early 2013 and it should be considered "Legendary" in the iOS synth world. Without a doubt, the best tool to learn and build synthesis engines. It certainly isn't your run-of-the-mill canned synthesizer (you must do a little work to make it go "beep"), but once you've learned some of the basics, the capability depth is unlimited. Audulus is well supported (check out the forum discussions, tutorials, and recorded live streams) and the developers and user-community are more than happy to answer any questions. You won't be disappointed.
Update (24 Jan 2018) - This latest update (V3.5) significantly improves the usability of the patch library taking advantage of the new iOS 11 Files browser.
Update (3 Apr 2018) - Another sweet update (v3.5.1) and the module library keeps getting better! Love the embedded documentation in the modules. Looking forward to seeing the Midi overhaul in another (hopefully soon) update as well as an updated Windows version supporting the SVG icons!
Developer Response ,
Aw thank you so much BDB-1958! Glad you think so highly of us, and thank you for updating your review for 3.5 - pleased you're enjoying that as well. We're going to have some new patches coming your way soon - over 500! - in the next little iOS update. Stay tuned!
The best guitar FX app on IOS
I know this is geared toward modular synthesis, but you can build anything with this app. I have an old Maestro Echoplex tape delay that I'm always trying to replace with a more convenient pedal. All pedals out there are lacking in one degree or another but none of them replicate the distortion when you overload the input by leaning heavy on a volume pedal. Well, I was finally able to create that effect with Audulus. You can mix any sound to any other sound have it all controlled with a volume envelope. Distortions in Audulus sound as good as Bias FX and are far more flexible. All the basics are there to build any type of modulation, delay, reverb, way pedal, etc.
The only thing it's lacking for guitar is built-in guitar amp/cab modeling. I'm confident you CAN pull it off with Audulus if you know enough about how to get that sound. I use AUM to route Audulus to Bias amps and control it all with MidiDesigner. It's the best multi-FX unit I've had, completely customizable to my liking.
With Family Sharing set up, up to six family members can use this app.
