No copy and paste into bars it's not going to be. 

Headphones. One ear listens to what was recorded; and analysed, while the other ear listens to the live being recorded. 

That way each individual note for each voice or instrument, constantly changes, instead of the copy and paste. Copy and paste is one reason why Computers and Piano's don't mix. But hey, Korg offers customized sound creation abilities. A Mini Grand would be ideal, but it only has one voice. :+) 

Sample patches banked as 'accents' and 'high lights' for here and there throughout each album, so as to break apart the similar structures, as well, splitting octave pathways for threaded -+ branching's.  

Start: Computer + Midi + Keyboard...

The reason I like KEXP so much regardless of Genre. Live! Though there are fingers pushing presets. 

Some places, the keyboardist plays the keyboard more than the keypad. 

Like Bam!!!
