Plug and play !
Recording both Audio and Midi (Novation Impulse 61) works like a charm !
Love having more inputs and having my MIDI keyboard connected alongside the interface !
And no need for any control software !
The Apogee One is an excellent interface BUT it won't work unless connected directly to the iPad.
So if I want to add some keyboard to something I recorded I have to disconnect the One, connect the keyboard, record and rewind and repeat ...
Not beeing able to turn the phantom power on/off or switch between extrnal/internal Mic without opening the Maestro app is also a bit annoying ! And the breakout cables Apogee uses ...
So far, so good !
