Fixed an issue with frame layout when cold starting into splitscreen on iPad.
Fixed an issue with piano keyboard having '3 note sticky behavior' after opening the iOS keyboard for typing.
Fixed an issue that may have caused Stem normalization to have low volume level under specific conditions.
Fixed an issue when dropping a stack of audio files onto MultiTrack from the Files app, where downloading from iCloud would cause the files to be out of order.

Previous Features:
FLAC (Free Lossless Audio Codec) and ALAC (Apple Lossless Audio Codec) implemented.
Added an 'Import' tab with Files and Music Import capabilities.
Increased the vertical size of the Tab Control on horizontally constrained devices (iPhone in portrait mode or iPad in 1/3 or 1/4 splitscreen view).

It's simple :)

Took me 15 minutes to finally realize this app can't record midi notes. It only records actual audio. Sad. I was looking for a daw like garageband, that could record midi data, but with the ability to freeze tracks... Since garageband lacks that very important feature. This isn't it. That said, this app does look freakishly simple to use and honestly it seems much easier to work with. For some reason, garageband always feels like it doesn't really fit in an iPhone screen. I wish this app had midi recording with track locking, but I bet that would be a very complicated feature for the devs, so I don't blame them for not having it. Maybe some day, who knows? But in the mean time I guess I'll reluctantly have to look elsewhere.

Top Shelf! Again I Say! TOP SHELF!

Harmonic Dog does it again!
New update is really awesome! 32 tracks on an iPhone or iPad is SOOOO COOOL!
Look folks how long this app has been around and it’s STILL ALIVE AND WELL! Not a fly by night outfit!
If you’re looking for a user FRIENDLY DAW for your iOS device look no further, this is dope!
I STILL use this app with great results!

I STILL reach for this app! It’s uncomplicated, EZ to use quickly gets me to the task at hand. I’ve NEVER had issues with this app and am stunned at the continued support/maintenance of this app! While updates are few and far between... when the update rolls in it’s MAJOR and well done!! AND amazingly FREE updates! That’s a huge win cuz I HATE SUBSCRIPTION services! Thank you Harmonic Dog YOU ARE AWESOME!!!!
Another great update! Now with looping until you "got it right" option! New device support too!
This is one my favorite apps! Even tho I have more "complicated" more expensive DAWs for iPad, this is the one I always goto! There's just enough bells and whistles to get a very good multitrack recording (depending on your device) and if you include it in the audio chain of AudioBus you're pretty much good to go until "mastering" The devs keep supporting this app which I'm very grateful!! This is app is Top Shelf!
Thanks Harmonic Dog for your continued support of such a great user friendly app!

Strizbiz ,

Great simple audio only Daw, I don’t get the auv3 part ?

As far as recording audio, if that’s what you’re after and not midi sequencing, this is an extent. If you want to mix in it and not export it to a more professional Daw or desktop Daw should I say for mixing , it’s fine. Personally I think the developers should have added an option to export stems to the files app. That would have taken things to the next level for me personally.
What I don’t get is how auv3 support was all.
I get using audio units effects for mixing....but I don’t get using audio unit instruments with it. You can’t play the majority of audio unit synth or instruments, at least not with a midi controller, and many don’t have onscreen keyboards inside of multitrack Daw. Adding support for audio unit instruments feels like a waste of time the way it’s been implemented, I’d rather just use a Daw where I can actually use them and not just be able to look at them.
Exporting stems would have been a lot more useful imo.
