Very nice great job but it sonds like a lot of work transferring to the EA7. Why not record the G70 ?
Bill I will answer your question here (wrong post)

The transferring of the finished seq from the G70 is no effort (via USB or Floppy disk to the PC and transfer to the E-A7 thumb drive.
This allows me to use the on board wave recorder .
Where as with the G70 I need to connect to my digital recorder (Tascam DR-07).
BTW: you know folks complained about the BK9 not really a top of the line(compared to the G70). But it was the current best offering from Roland... and guess what the E-A7 is the current best offering from Roland

As for not being full size keys.. the difference between the BK9 and E-A7 is about a quarter inch.. mostly because the E-A7 housing shrouds the keys, where the BK9 is more exposed.
Both models would be more desirable if they shared the same features..
