I played keys before bass. its actually why I turned to playing bass. smallest book ive read? cool keyboardists in rock bands. Seriously though, I was usually laying my bass tracks myself. I did a lot of syncopated rhythms akin to god lives underwater, just not sequenced. The way I got around frequency cancellation, particuarily in the low end was to build the voices in the keys (Roland D-50 and D -70) in a frequency specific area(s) so as to not step on the low end of the drums and the bass. Also, most keyboard amps and pa's suck for keys. I played mine live through a Roland JC120. Great amp, true stereo and dosnt throw out too much bass. Throw on a little distortion and verb on it, makes for a cool sound.
Ah, the Roland JC120 - those were great amps! I did a 1982 tour with a "Name Band," during which those amps showed up in all sorts of ways and functions at rehearsals and on stage…including keyboard use. A genuine classic.
