I drive Sounddiver (3.05) on Windows XP and Iam able to control the microwave XT (OS 3.33). But when I try to change any of the sound defining parameter in the edit-window of SD, these changes can not be immediately heared from the microwave, these can only heared, if I use the send function. This is boaring, when I have to use the send function after every little small parameter change. Is there any help?
