> There's no canned solution that I'm aware of - You pick your poison. Quite. Someone did try a system back in the 80s in which a synthesiser/ electric piano could tell what key it was being played in and alter its notes to that scale. Doesn't always work in an ensemble piece because you need to know what other instruments are doing, as it's those you should mostly be harmonising with.
