Hmmm, am I missing something? I didn't think that any version of the Marantz remotes supported custom beeps and tones. That's supposed to be a Pronto only feature.

Now it may be that a beep shows up in your action list, if you imported it from a Pronto, but I don't think it works, nor can you add one. This would also explain why Tonto isn't letting you do this either.
