1. QMidi worked like a dream. I purchased the USB UNO Midi Interface (USB to MidiIn/Out) which goes from my Mac to the back of the E3. I am then able to play all my midi files. SUCCESS!
2. I then went to Guitar center looking for the Cubase LE Bundle but they didn't have what I was looking for. I had the urge to experiment this weekend so I purchased an alternative called Studio One 3 (http://studioone.presonus.com) by PreSonus. It was bundled with the Audio Box Studio (http://www.presonus.com/products/AudioBox-Studio).
I am ABLE to play the Piano where the midi notes are captured within the STUDIO One 3 software BUT I still am not able to send the MIDI back to the piano where it will play the keys.
In using Qmidi which I think confirms that My cabling is sending Midiback to the E3. Fair assessment?
The "receive" and "send" Midi setting within the Studio One 3 software has the USB UNO selected for both but no luck.
Thanks in advance for your responses.
