If this is your only concern, forget it, I'd say. When the 'Precision' electric bass was introduced, many acoustic double-bass players of the world refused the concept, on the grounds that it was 'cheating' to have 'precision' frets, and that 'real' musicians had no need of such artifices. The World has moved on; 'clicks', backing tracks, samples and more have all been embraced by the music scene and the public in general. There will always be dinosaurs, but the real issue will be 'Are you (as a band...) capable of playing to a track..?'. If 'yes', get on with it with no qualms or reticence; if 'no', find a keys player or re-arrange/drop songs that don't work with your line-up.
