I think Rim's having a much needed rest after what I can only assume was a very testing launch for Auria Pro. Hopefully 2017 will see a vigorous return to the iOS quest for a robust and modern DAW. With any luck Apple will introduce MIDI latency 4096 samples, phase out IAA and make AU a format that can provide a stable platform for the future.
Most DAW's took a long time to fine tune their MIDI implementation so it's early days as far as I can see for iOS and Auria Pro.
