I have a question. all I want to do is record my patterns into a song 
and use the track enable/mute buttons to bring in and out parts 
throught the song, and do all of this in real time. I know I can do 
this in step record, but when I bring up real time record mode I am  
not sure how to get my saved patterns to record into real time song 
mode. thank you for your help -
