Almost always use at least two keyboards. don't do many 1 hour jobs and have three standing jobs where I leave equipment, so that makes it a little easier.
One house job: B-3. Rhodes and Sh-201. Another: MS-60 and a midi controller with Yamaha Tone generator. Another: Another MS060 and GW-7 on my right hand. Sometimes Iuse three: Nord Electro or Hammond/Suzuki on the bottom, SH-201 on the top and GW-7 or similar on my right hand.
I just like to do things that way, and I have a sound person to set-up everything.
