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!

My view

This app was a game changer for me as an evolving musician!!! Even Considering that I am basically computer illiterate, I would say this app is very user friendly. This app has helped me grow as I experience the recording process from the perspective of each instrument in a band.. Easy to start recording and learn tons of tricks as you go. Very useful tool for writing and recording original music. Only complaint I have had in the years I have enjoyed this app is that the latest update (5?) messed up the sound on All previous recordings. Everything sounds like it’s in a tin can now. I have not yet tried to record new material since update.. so no opinion as of now.

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.
