I’m looking for software that will have designs and such move with the bass line of music. One that can be controlled with the keyboard to give you different designs and things and you can change the different tones they will react to.
The majority of the posts above me recommended PhotoShop but what if someone does not have $699-$999 to spend?
Also, I'm assuming they just wouldn't go download an illegal copy like most freelancers/webmasters out there...
GIMP is also another alternative which can do almost everything in PhotoShop (not talking about the extended version, of course).
One pro to GIMP is that it's FREE.
