Imagine, Create, Play.

“Audulus is a modular music processing app.”

I have tried all the other modular synthesizers on iOS. None ever really impressed me very much until now. Even though its not the first modular synth to hit iOS, it does perform well, and I like its U.I. in favor of the others. Audulus arrives and changes my whole perception of this kind of music application. I’ve known about the enthusiastic following of the Mac version, so like many of you I was pretty psyched about it porting over to iPad. I had been looking forward to finally give it a try. I wasnt sure what to expect? I am happy to report Audulus is a very clean, and extremely capable modular synth. Everything you need (and more on its way) to create your own synth is before you.

The U.I. is brilliantly designed with really just two primary buttons viewable on the screen at all times. Located at the top left of the screen are the two buttons. One is an info of sorts, button that identifies things on-screen, and the other is the main menu. The modules, nodes, tools, and all are neatly tucked away out of sight. All those functions are easily accessed by touching the main menu, function button with a second touch elsewhere on the screen. Making connections is as easy as drawing a line that connects the parts. A main circular menu made up of 8 smaller circles contains all the mods and nodes, each with its own sub menu to drill down to further, finer functions. It’s really quite elegant in appearance. Simply select the function you want, and it appears on-screen. It wont take long before you clutter up the screen with virtual wires and modules. Everything responds very well to touch and gesture input, so moving individual parts around is a simple task. Just touch and drag.

Creating your own synth from the many available tools is a lot of fun, and very satisfying. You can make pretty much anything you can imagine. Simple sounds to highly complex ones that move, breathe, and evolve can be achieved with a little effort and understanding of how everything interacts, or responds to others. It may be advisable to check out some of the Audulus video tutorials to learn the basics or expand on your existing knowledge. Only a few patches are shipped with Audulus, so checking their forum and looking at the downloadable patches other users are sharing will help get you on your way.

Audulus just feels right. Its like painting with sound. With Audulus you are set forth on a huge world of sound options. Choose one or several oscillators each with its own waveform. Set the routes however you like to obtain the sound you’re going for. Add effects like, delay, reverb, distortion, low pass filter and more. It’s just amazing when you think about how much can be done. It all flows logically.

I have been quite impressed with the audio quality. Audulus really sounds amazing! The onscreen keyboard is very responsive, and I havent detected any latency at all.

Currently Audulus does not record, and you cannot share or move sounds without an internet or computer connection. Record, and AudioCopy/Paste are noticeably missing. That is a bit off-putting. From what I have read (I emailed to confirm but did not get a response) these are features that are a priority to be added. I sincerely hope sooner rather than later. For now we must get along with emailing our patches to each other or ourselves. Not great for those scenarios away from an internet connection, or computer.

Just two buttons?MIDI users will be pleased to hear that Audulus is fully controllable, and will detect a MIDI connection right away.

“Control everything with MIDI

Control Audulus with your MIDI controller keyboard or control surface.”

I’ve had some moments where a touch did not produce the response I was intending, or when trying to draw a connection the module moved instead. It got a little frustrating, but after some time it seemed that a lot depended on how far in or out I was zoomed. I got used to it. Really a minor gripe. Audulus looks and sounds professional. I think most people familiar with modular synthesis will appreciate this most, but really anyone who wants to have A powerful tool to make their own synths from scratch will also find Audulus to be a blessing. This is a sparkling addition to any iOS music app library.

I recommend Audulus, but until Record, and AudioCopy/Paste are added, I offer 4 Stars!
