I guess this is a rant because I'm not sure advice will help me, tho feel free to weigh in if you have some ideas.
I'm playing keyboards in our church band. (this is not to be confused with playing piano - piano is a paid position, keyboard is volunteer and is usually just playing some strings or organ parts).
There are actually 2 of us who play keyboards. the other guy is an older gentleman who only plays hymns. I play on the contemporary stuff. This makes for an odd arrangement because it means during any given Sunday, we might swap back and and forth on the keyboard 3 or 4 times since we play about 1/2 contemporary and 1/2 hymns, but in no particular order (well, there is a "theme" to the order, but it means we might have 1 cont, then 1 hymn, then 2 cont, then 1 hymn, then 1 cont then 2 hymns...).
The keyboard belongs to the church and that's what we play. it's a Casio 88key weighted. (personally I prefer to play synth keys for organ and strings, but this is what we have). we have a monitor for all of the band and the monitor that was being used for the keyboard itself was only the built in speakers.
I couldn't hear the keyboard that way because the band monitor has the keys turned way down and those speakers on the casio are crap.
so I brought in my keyboard amp and plugged it in. sweet! now I can hear myself!
however, the other guy refuses to touch it, and also refuses to touch the volume on the keyboard itself. so when he goes from playing strings (low output) to playing organ (high volume output), he gets blasted by the keyboard monitor and then proceeds to gripe about it.
so I end up having to change the keyboard amp settings after each time I play before he steps up to play a hymn. personally I prefer to leave the keyboard amp volume alone during a set and adjust the volume on the keyboard itself if necessary (and the FOH is good with that - they can adjust me if necessary in the house).
but this is a little frustrating for me - not just the adjustment of the keyboard amp, but the whole situation. going back and forth during a set has been more than a little frustrating, especially when the other guy complains about the extra equpiment, the volume, and he hasn't said anything yet, but I suspect he doesn't like his patch settings changed either (I really have no choice in that sometimes).
so... like I said, it's really just a rant...I will probably talk to the leader about it soon and see if he has a better solution. otherwise, I'm afraid the two of us will likely have "issues" soon.
