Hello folks I'm seeking advice on getting a new board. Last time I settled for a DGX-305 which has suited me just fine, however I now have a new steady gig. I'm going to be a backing musician in my brothers band. I'll be playing keyboard, handling bass, drums and organs and pads, while he will play piano and we have a guitarist playing guitar. So what type of board will handle this kind of job? I tried using my current setup with the DGX and my trusty old Boss DR-3 drum machine, but it all sounded awful and I didn't have enough time to switch the beats... We like to switch songs rapidly somtimes before the one we are playing is over creating sort of impromptu medleys. What sort of feature could ease my job when my brother shouts out "country rock 130bpm G major) in the middle of a bossa nova?
Would be great to get like some sort of 1 touch button setup where I could switch from 10-20 different setups in a split second...

So far I've checked out either getting a new drum machine, the DR-880 has user banks, don't know if they will work for one touch settings, but at least it's cheaper than a new board but I don't know how well it will work.

Secondly I've considered getting the S700 or S900, but maybe I need some kind of workstation synth instead? like the MO6 or Korg TR?

My budget is max the price of the S900, preferably the price of the S700

Any suggestions?
