BTW, Montana.... If ALL your UPGs are skewed one way or another (and you can hardly blame the G70 for THAT, sounds like a monitoring issue) between Keyboard and Style Parts, there is a simple Balance knob, that can skew things back the way you want without having to adjust the UPG's...
And, you probably already know this, but just in case.... It REALLY helps to tape yourself under gig conditions (same PA, volume levels etc.) to get an objective idea of the balance you need between 'live' Parts and backing. Most of us make the mistake of making our 'played' Parts too loud, so we can hear ourselves well, but when played back, often shows us 'swamping' the backing.
Oh, and don't forget to include your voice, if you sing at the gig. That can often change the perception of a mix...
