Abstract
We study two simple ways of adding an infinite number of direct-channel two-particle thresholds to the Veneziano picture, which usually contains only resonances in the direct channel. We investigate the high-energy behavior, positivity, and $l$-plane structure of the resulting amplitudes, which turn out to have Regge cuts in addition to Regge poles in the crossed channel.
