yo that is why i posted this, to hopefully inspire everyone to want this in increasing measures and to show others that you are not "stuck" on your instrument it is not a worship jail, you don't have to get up/off to experience the most of God's prescence there is freedom right there. worship is spiritual, your spirit can be doing the lifting of hands and dancing, and you can be expressing your heart through your instrument
ask God to show you this, and how powerful it is. just because of how different it is it will blow your mind- if you let it happen/ let him teach you and lead you to this place.
it may take a few times sitting/playing through the times when you just want to get up... at those times if you stay he will begin to show you and reveal to you. it will cause you to focus on expressing you worship through your instrument. make your instrument serve you/ be YOUR vessell of p&w and before you know it, you'll prefer to stay on rather than get up.
(this is barring God clearly telling you he wants you to stop and get up)
seek him on this, you won't be disappointed.
