Hi. I want to select a device parameter and then set its values (using M4L.api.DeviceParameter). It appears that I should be using the abstractions M4L.api.SelectDevice and M4L.api.SelectParameter. However, these should be put in a bpatcher and I'm having trouble seeing how to make this work. Can someone show me how to create a menu of devices and parameters so I can use the menu output to set device parameter values please? Thanks, David.
