Recorded 48 tracks from my Midas M32r!

Great DAW app removed one star because it’s a CPU hog when running instrument synths. AUM can handle 8 plus synth apps on my iPad Pro, AE gets cpu overloads with 4 synths. I hope this can be fixed in an update. Great for backup recordings to my iPad off my M32r so its worth the price just for that, and able to get files off to my Mac Pro easily unlike N-track where you have to jump through hoops to get them off. That being said N track has easily selectable channel outputs when connected to my board, with AE you have to setup mix buses to output each track to separate channels. N track creates them for you when you select an output. N track also can handle a lot more AU synths. I really like AE so hoping they keep improving on it and for the price it can’t be beat.

I have all of the iOS DAWs and this one is #1

Like the title says, I have all the iOS DAWs including Auria Pro, Cubasis 2, GarageBand, Nano Studio 2......etc, etc. I have used Auria Pro and Cubasis 2 as my main workhorses. Auria Pro for its bussing, Cubasis 2 because of its much better work flow. By sheer accident or by divine fate I stumbled upon this DAW and at first I almost passed it by. With the puny $9 price point what could it possibly offer that I already had? Well, for whatever reason I decided to download it. My two biggest gripes about Cubasis are the lack of busses and lack of markers, which is something I use quite a bit of. Auria Pro has the busses but I just cannot get into the workflow of that software. Audio Evolution has it all and more! The workflow is seamless AND it covers busses and markers. I think the developers have lost their mind on the price point! If you are looking for an iOS DAW or are just tired of all the work arounds required by the others then I seriously suggest giving Audio Evolution a try. THIS is what I’ve been looking for all along! I’ve been an iOS musician since 2014 and a recording musician for over 35 years, so I’ve had some experience with these things. I finally feel like my search for an iOS DAW is over.

Intuitive and transparent

I am mostly using this daw to mix sound files to make ambient fixed media pieces. I have used most other ios daws and find this app to be quick, transparent, fast and doesn’t get in the way. If a bit quirky at first, I adapted to it quickly and it is now my primary ios daw. There is something organic about using my fingers to manipulate the file instead of a mouse but then transfer to the desktop for a more robust computer environment or quickly store files in AudioShare. I am not playing midi instruments and recording voices ( maybe a bit) as many others; so, maybe I can’t entirely speak to this. But this seems like it would be quick and great for this and the tone boosters mastering purchases addons are reasonable and excellent. The purchase price of the app is much cheaper than others and I prefer it regardless of price.
