I have a serious aversion to subscriptions on iOS/iPadOS due to Apple’s App Store policies. I am making a rare exception for Audulus 4. The amount of work and love Taylor has sowed in is extraordinary. So intuitive and easy to use, seriously thank you Taylor. Being left handed I find the interface to be acceptable except when switching from Performance Mode to Edit and back. A dedicated button in the top right interface panel instead of the slide out would be quite helpful. Try navigating with your left hand and you’ll notice your hand blocks the view. Thanks again, I have purchased each iteration, 1,2,3 and now 4. ❤️

Well.. I’m nowhere near getting my head round this but I can see what an incredible app it is ! The gui is superb and I have managed to make something that resembles the start of a musical track . It’s fun and has huge potential. Add to that the multitude of other apps and effects I have to play with in AUM, along with other musical instruments I can play in via my Irig and I don’t think it will be too long before I have a good track .

It’s difficult to imagine why the developer thinks MIDI functionality should be behind a paywall. Have you looked at any other iOS music apps lately? Ever? Also, the persistent banner in the upper right corner urging users to upgrade to Pro is annoying. Make this smaller, minimizable, or make it disappear after the app is open for a few minutes. In-product help is totally absent, except for a fairly uninstructive tutorial. Figure out some kind of documentation- a tooltip or two would go a long ways. What happened to the long-hold menu with options like ‘Help’? Hard to see that this is much of an improvement for the typical user, beyond the slightly nicer looking UI.

Subscription model is for services. Not for featers that runs on user device. So, 1 star.

When I at music school learning electronic music production , this app taught me a lot. I still need to learn the maths better and would Love if there was one stop resource to learn what’s needed to make the most out of this most interesting app . It’s must have app.

When I create a patch I press the “+” button, but I cannot select patches to delete them. Clicking the “Select” or “Import” buttons does not do anything.

Opens to the file browser, no modules, nothing. Tried deleting and reinstalling, nothing. It worked in the past and I liked it, hope I can figure this out.

Avoid. Mi rack does everything that this does better, number one mi rack works. This doesn’t. Do not even consider Audulus. It’s a waste. Has had months to pick up and improve. Hasn’t happened. It makes no sense. Envelopes don’t seem to work at all. There is no obvious logic to how to get things started. Why is this app still around? It’s as unusable as ever.

Audulus is my favorite software to spend time in. It suits different moods whether doing disciplined work or scratching a creative itch. I even find myself working on little patch-puzzles instead of playing video games. The aesthetics are refined. One can approach the canvas like both a painting and a logical structure. There are standard signal types, but no rules! Just start dropping modules on the canvas and freely connect any output to any input. A casual/fun approach to learning is encouraged. There‘s no ‚wrong‘ way to make a patch. A non-technical approach finds its own results. And over time there‘s also a rewarding amount of depth.
