A must have

These apps have taken my iPad production to the next level. Buy the bundle, it is a must have as it will augment all of your current music apps.

Figuring out how to use them can be a little daunting, I recommend just playing with one at a time against a sound you already know well so you get an idea of what each one does

Nothing else comes anywhere close

To how well put together all these apps are

Clive Luis ,

Auv3 version will make this unbeatable!

Im rating this four stars only because its 2017 and Auv3 is gaining prominence.
I hope an update is forthcoming . .. at least for Push and Peakq ..the best of the AUFX lot
As far as EQ , IOS and simplicity goes , peakq is as good as it gets. ZMors eq is the only other one I can think of.. but it does not have a spectrum analyzer .. ...for that feature alone you need to lap up this app!!!

Developer Response ,

AUv3 versions for all AUFX apps are planned!
