I sounds like the effects loop on the GR-33 is sending the normal 
guitar tone out to the Talk Box and EDP and that the effects return 
is being mixed with the GR-33's synthesizer sounds and then routed to 
the outputs. That would mean you'd be hearing looped guitar (with 
Talk Box) and unlooped synthesizer sounds.

Does the GR-33 allow you to select which signal or combination of 
signals is being routed out the effects send?

If by "tone information" you mean the sounds of the GR-33's built-in 
synthesizer, the answer is NO. MIDI cables do not carry real-time 
audio signals. They are meant to transmit control data only.

If by "tone information" you mean a data dump related to the GR-33's 
built-in synthesizer, the answer is still NO. The EDP wouldn't know 
what to do with the Roland's  system exclusive data.

I'm not directly familiar with either the EDP or the GR-33, but it 
sounds to me like you could use a basic tutorial in audio signal 
routing and the nature of MIDI. I'll be happy to help you with that 
off-list if you like.
