[sdiy] circuit to create gate to accompany cv

There is no way to reliably capture note-on events from a single CV 
line.  Consider the case of unchanging voltage that might involve two or 
more consecutive note-on events at the same pitch, a common occurrence.  
There's no way to discern note-on events because the voltage never changes.
