Anyone using their iPP for playing and/or recording music? I've been using my basic 16Gb iPad Air 1 for playing guitar while using amp/pedal modelers (BIAS,S-Gear,Mercuriall) and recording into a DAW (Aura,Multitrack DAW,Garageband). The Air 1 has worked 'ok', so far. I definitely would prefer a larger screen (especially for manipulating DAW knobs and sliders) and I like the availability of more (ok, much more in comparison) power for multitrack recording and mastering. I don't currently use an audio interface but want get either a Dock or stand alone interface. This is where I would think the iPP's USB 3.0 data speed capability could shine in handling multi port data flow on the interface. Are any of you guys also using an audio interface?
