I'm having a really bad latency issue. I'm running Loopy HD and Audiobus on iPad Air 2, running vocals and guitar through a Tascam US-800 audio interface using Apple's camera usb adaptor. I've tried all the solutions I've read so far but no luck. Seems to be working fine when I record using Apple headphones. Setting up Audiobus or changing latency setting in either app doesnt fix the problem. Running other apps through Audiobus is all good as well. I'm mildly obsessed with Loopy right now so I really need a fix here. I would like to start using loopy in my live shows if I can get it to reliably work. Michael, if you have any advice I would greatly appreciate it. This app has become an integral part of my song writing. Thanks and great work!
