Hi Peter - I purchased both the iGrand and the iLectric a few days ago from Google Store, each with their Expansion Packs 1 & 2. I am running these on a brand new Samsung Galaxy Tab S2 9.7 (32 Gb) with Android 6.0.1, Yamaha MOXF8 keyboard & ICON Cube Mi3 MIDI interface - the expansion libraries seem to work only intermittently, sometimes all the iGrand pianos are available, sometimes only the first few. Other times all the iLectric pianos are available, sometimes only the first few. Sometimes none of the expansions are available?
Has anyone else got this problem I wonder?? When available, the pianos all sound very good with no latency!
Grateful for any help! Carl in the UK
