I prefer to play and the pastor most definitely wants me to play.
I know that one or two members might give me a weird eye, but I tell them after the service the importance of playing during prayer. Like others have mentioned, the playing must enhance rather than compete with the prayer.
Regarding the sound controller issue- back at home I was mainly doing sound- I learnt that the sound control team needs to always be observing signals from the stage and from the musicians, and also understand BASIC CHURCH RULES/ PREFERENCES [eg, during prayer, reduce music volume or mute music volume, depending on church directive etc]
