This live verses recordings has been going on since the first rhythm unit was added to an organ, in I think the sixties possibly seventies, (Yes in those days even a rhythm unit was considered cheating) so I doubt if we will ever get everybody in full agreement.
The way I look at it however is that, most keyboard musicians (OMB) what to create a sound that is similar to a live band, group or orchestra etc, unfortunately we do not have enough limbs to play all the individual parts, so I see no problem using Midi, Wav, Styles etc, to get this effect, providing as much as possible is played live.
These are my thoughts yours may be different.
