Just bought a jv1080, excellent piece of engineering. Just wondering with the user section, are the patches in that at all different to the ones in the preset banks? Or if they are, are they worth keeping? I'm a little hesitant to overwrite and a few editing software programs keep stuffing up. There's all these little changes I've got to make. (Stereo delay on uilleann pipes? What were they thinking???) Thanks.
