Hello again, "Thanks for your quick reply. I'll try to make it a little clearer by giving you a concrete example: What I did was storing one sound patch together with the midi information (e.g. switching amp modes on my JVM) on the U01-1 and stored another sound patch with different settings and different midi information (e.g. switching to another amp mode on my JVM) to U01-2. Switching between those two patches is no problem and all data including the midi "amp-switching" were transferred. So far so good. But if I now only want to copy the U01-1 patch to another userpreset on the GT-10, (e.g U01-3 ) all sounddata is transfered to the new patch (U01-3) except the midi information!!! I have to do the midi switching within the copied preset U01-3 for the JVM again from scratch! This can`t be the truth especially while using a lot of user presets and amp mode switches for our shows - often with changing set-lists and the wish to reorganize these setlists thru the library software! Hope you got me now? Would be great if you could comment on that! Thanks and bye for now." bookwood
