I agree with the first post, the patch storage and loading system should be re-designed, sometimes it happens that an undesired patch is loaded with any control possible when selecting it from the menu.
another useful thing would be, for the CS-80V , to make possible the loading/save of a patch for each single " synthesis line", that would mean a closer come to the original way of storing patches and, most of all would make more flexible to run presets, you could then select patches in every way you want it to be. I happened to show this to Xavier some time ago and he seemed to agree to this way. Could my idea be an affordable improvement?
