I would sure think so. This is meant for one person to play a full orchestra themselves. Synchron Prime is a traditional orchestral library, so if you want five different instruments/sections, you would need five people on five keyboards.
Of course you aren't really explaining how many people you have playing. It could be that you actually want one person to play just flutes on one keyboard, and another person to just play oboes on a second keyboard, and another person to just play clarinets on a third keyboard, etc., and if so then Prime might make more sense.

Are there any clear benefits with Smart orchestra over Prime edition for live playing except the price?
