FM Voice Editor

You don't have to be a wizard to program FM sounds. You just need good controls. Patch Base makes FM easy to work with by showing you the layout of the currently selected algorithm and the envelopes and settings of each operator. You can finally visualize what's going on inside of the DX7ii, and once you do, it's not that complicated.
