I am one of those 'good' keyboard players. However, whenever I play in my melodies into the MIDI editor I am finding that most of the notes' velocities have to be (sometimes drastically) recalibrated. It's a fact of life, so lately I am playing things in more sparingly. True, dynamics and other automation can apparently be more realistic in this manner. However, personally, based on experience, I record automation after editing velocities and positioning of notes on tracks.
Guy, thanks for the input. I'll try to do more of what you're proposing. If it works for you, it should for me too.
Cheers, John.
