I received an early copy of Audiobus for iOS yesterday to try it out while playing live MIDI through it. I was pleasantly surprised that it barely adds any latency and reacts really well. The shortcut bar is extremely useful and app-specific icons makes it very easy to interact with backgrounded applications while having another app in the foreground.
In this short demo I’m using my Eigenharp Alpha with a pre-release of PPG WaveGenerator. It’s fed into JamUp for additional effects and amp simulation. Loopy HD sits at the output side to build up the loops. I’m also using FunkBox, MIDI-synced to Loopy, for the drums.
The Eigenharp is connected with iConnectMIDI through a USB hub, into the camera connection kit to send the MIDI with virtually no latency and at a very high bandwidth. I use a Matrix USB/SPDIF interface that’s also plugged into the USB hub and recorded the iPad audio digitally without any post-processing.
This is all extremely promising imho!
