Boo, my issues were from comparing it directly to the Sd1.
The Midjay doesn't have a Rotary effect for the organs (can't slow down and speed up).
The vocal harmonizer is different, it is a Vocoder. I'm getting used to it.
Only one mic input (SD1 has two).
I'm sure there are a few more, but all are relatively minor. In C that would be Am

So far the advantages far outweigh the drawbacks.
Gotta run,
