  3. Hi, your ap is very good, runs so smoothly. I have one problem. I sing karaoke with Smule Sing. After recording a song, there is an edit stage where you can add audio effects like reverb etc, but just before it gets to that stage, the ap stops working. Such a pity because it is by far the best app for audio quality. All other emulators seem to stutter with the audio recording which causes malor timing and sync problems. Hope there is something can be done.
