[sdiy] PPG my ESQ

[Grant Richter]

I wasn't thinking about the multi-timbral capabilities of the ESQ.  
That would severely complicate "spoofing".

Perhaps the trick would work with poly mode only boxes. Or something  
like a Moog Source or OB-1.

Those mini DX7 modules that went in a TX-816 rack would even fit  
behind a MOTM panel.
