Hey Ryan,
I use the same setup for live and studio because my studio gear is on stage with me at the venue. I am on staff full-time for Destiny Ministries and the Gateway Prayer House. I play live every week for a living when we have Sunday services at 11:00. We also travel a bit. Our church usually has 30-50 people in attendance but on the road we could have between 50 and 2000-3000 people depending on the size of the conference, etc.
I use a Yamaha DGX-500 as my controller and piano sounds and I MIDI to a Korg PA1x-Pro for everything else so I can do the one man band thing. If you go to my webpage
http://360.yahoo.com/korg4god you can see pics of my setup - the first two albums are actually my old set up before the PA1X when I used the DGX-500 and a Korg N264 on top. I just used the DGX's drums and split/ layered sounds on the N264 to cover other sounds. The last album is with the PA1X but now I have fixed my Apex stand to allow the PA1X to sit at an angle so I can access the controls and touch screen easier and see the screen on the DGX easier as well.
