                                Gern Blasnton, 23.06.2018Want to Like it - No Audiobus or AUMDoes not load in either Audiobus or AUM. Also, the vowel pad has no graphic effect as pictured.

                                Mozfits, 26.03.2018I like it but...Can’t figure out why when the app is open it disables sound output to my Bluetooth headphones. Makes it useless when I’m traveling or on the train.

                                Eriptron, 05.11.2016Could be goodSome of the controls are stupid sensitive for small adjustments. Interesting but not much more than a novelty.

                                Robozombie, 26.09.2016Fun, but quietI like this a lot but it's almost inaudibly quiet by default on the iPhone 6s.

                                Hydra vein, 23.09.2016Quite good!Now, this has Audiobus. So that's it. Freaking awesome stuff! Only thing this NEEDS is Audiobus and IAA. Fun lil app. Great sounds.
