We extend the algorithm for matching fixed-order tree-level matrix elementgenerators with the Dipole Cascade Model in Ariadne to apply to processes withincoming hadrons. We test the algoritm on for the process W+n jets at theTevatron, and find that the results are fairly insensitive to the cutoff usedto regularize the soft and collinear divergencies in the tree-level matrixelements. We also investigate a few observables to check the sensitivity to thematrix element correction
