Currently, I've been using a Roland Gaia sitting atop my Yamaha CP-70, but the 3 octave keyboard is quite annoying. There's room atop the piano for a 4 octave keyboard and was thinking of getting one of these keyboards and use iPad apps as sound engine.
Does anyone have experience with either? Do they work well with most music apps? I'd mainly be using Sunrizer, DM-1, PPG WaveGenerator and AniMoog.
