Define better. Do you mean more dynamic, more variety, more 'locked on' to your music? As many have suggested, a more powerful DMX controller is needed. Computer based controllers such as MyDMX will give you the most bang-to-buck, but you would need to have a computer you don't mind bringing to jobs. Since you say you also play in the band, you'll want a controller that doesn't need a designated light tech to run. Possibly consider a controller that can be triggered with your feet.
