There's now no need for me to take any of my keyboards away with me when touring abroad. I now just connect my iPad Mini to ANY supplied keyboard via a standard midi connection. The apps I have installed onto the iPad are:
Hammond B-3X (Gives me all the Hammond sounds I need)
NEO Soul Keys (Gives me loads of Electric Pianos)
Galileo (Gives me the VOX Continental sound I need)
Ravenscroft 275 Piano (Excellent acoustic piano sound)
iSymphonic Orchestra (For big Orchestral sounds)
Bismark bs-16i (General Midi sound collection)
