If you search the RJM forum you wil find several threads for the Whammy DT including a few of mine. You might fond that you can do what you want with it as my issue was quite specific. Having reread one of my threads it was the way the Whammy and Drop worked individually. You might be able to get one or the other working properly. Also my issue revolved round trying to set up a page to be able to manually scroll through presets on the fly. If you are just sending simple PC numbers it might be OK.
Actually managed to figure it out. It was as simple as changing the channel on the Whammy. I knew it would be something I was overlooking. I must have gotten lucky with the FCB1010. Thanks for the help!
