Good quality effects.. its nice to see a company properly address this gap in ios effects apps for vocals. PLEASE give us more than 5 custom presets... thats just not enough to recall. You could consider having the horizontal list (a b c d... etc) of presets scroll like other apps to allow for more slots without significantly affecting the overall interface design. Also, please give us the abilty to stack effects and give us more sophisticated options for creating harmony like in your hardware products... even if it meant an additional in-app purchase or pro version. Id gladly pay extra for those features.
