Hallo Urs, this Problem occurs only with the microwave XT, with other synthies in my SD setup Ive no problems. I already have put my settings as You mentioned: Auto audition: on, Midi thru: on, hold transmission: off As I read, if I change Parameters in the SD Editor, SD should immidiately send short "parameter change sys excl. messages" to the synth. Ive the impression, that this feature does not work properly. I see, that the MicrowaveXT gets Midi information, but there is no hearable sound change. But: For Microwave XT emagic offers a so called "modul" instead od "adaptions" that are used for my other synthies in the setup. Is it possible, that the modules pricipially dont show this feature at all? --- In sounddiver-users@yahoogroups.com, "Urs Grossenbacher" <ursgrossenbacher@b...> wrote: > Hallo Werner! > > Does this problem only occur with the WaveXT or also with other synths? > When yes: please give more information on your setup. > When no: check your settings under Options...
