Hello! I have been using VoiceJam Studio for some time now, and it has been okay but after the most recent IOS update the FX stopped working completely. Whenever I change my FX from Dry to anything else, I don't hear anything! I purchased the Voice Rack FX app but the VoiceJam app does not recognize that it has been purchased! TC Helicon needs to do something about this! I have a 3rd Generation ipad mini, and I use the irig pre XLR mirophone interface to connect a condenser mic (Behringer C-1). PLEASE HELP! I AM DESPERATE!
