Ted I am experimented with similar ideas using the G70 and EA7.
I run both keyboards independent of each other so I can use them normally.

The difference I use one as the midi clock..

This allows me to play a sequence on the G70 (primary) and send the midi clock control to the EA7 in style mode.. This allows me to do some of the things that I always liked on Yamaha.. like playing a different drum pattern with the sequence..

Also because the G70 reads the chords on any SMF.. I can play the chords live on the EA7..in style play..
This way I can have a mix of both with mutes and edits..

All other info is not transmitted or received.


This combination is like having 256 polyphony. 10 fills 8 variations 8 intros and endings. 6 pads , 9 assign buttons, sampler , D beam Drawbar organ, 15 sliders with multi functions, Audio player Midi recorder and wav recorder two mic inputs, and harmonizer, unlimited performances and storage up to 2 terabytes.. Touch screen and after touch.. Also two pair audio inputs, 4 separate outs and 16 effect processors.

Sounds like a pretty nice dual manual arranger workstation,, doesn't it?
