Dub-berrific!!! Presets Yes!


thanks so much for making this app
it is a clever goto fx staple i use in creative times of needing something ....just a bit different but exploring like scientist

this app allows that creation without being too complicated that you cannot figure out how to man the controls

great job

Coming from a straight hater this app is awesome. For FREE, then s should be criminal

Literally Amazing


This is a great effects app with a great interface. And unlike most free apps, free does actually mean free. The filters are great and when you combine those basic functions with the two x/y pads, smooth sample manipulation via the play head and the ability to apply LFOs to parameters this is better than many paid fx apps.
