considering the amount of gear you have especially the sampler , I would try and use it to it's full potential at this point , and I know that can be tedious but production wise you can do a lot with just the sampler by mixing down loops of stuff in your track and just use the EFX and EQ in your sampler and remaster each thing and send it out individual outputs and re-compress if need be and keep rebuilding the track until you acheive the sound your looking for :)
