Roland A880 Patchbay.

Hello! I recently bought a S/H Roland A-880 midi-patch bay which I believe is a fantastic piece of equipment. Unfortuantly. I'm a human being of average intelligence and NOT a maths genius! The manual which came with it assumes the latter and I'm stuck! Can someone currently using the Roland A-880 please contact me at my e-mail address (dj_parris@hotmail.com), and explain to me how to use the system. All I can get from it at present is a 'thru', signal so that the midi signal sent from my Korg,Roland or Yamaha synth appears on the Cubase screen. When I try to get Cubase to return the signal (i.e. attempt to play-back the piece I've recorded there is absolutely no response on any of the keyboards despite selecting the appropriate midi channel.

I'm a new-comer to all of this (just a DJ trying to remix some tracks), and I'd like a clear, concise and understandable explination of EXACTLY what needs to be plugged into where....

If someone would PLEASE be kind enough to help me out I'd be much obliged,

Thank you,

Parris.
