I had a duo years back with just this setup as outlined by montuno..
Bass player and me. No arrangers back then of course, and the drums were supplied by a Boss DR110. I played a Yamaha PF-10. Even then my back was telling me to give up the Rhodes
The only tip I will make is that what we did, was to jam together over all the songs (no drums) until we were comfy with that, then add the drums a song at a time adjusting them as we went. Easy, as both of us now knew where the other was going on songs..
I have to say that duo was one of the most enjoyable gigging music experiences in my career...totally free to go wherever we wanted with a song, or just do it bog-standard!!
