[sdiy] Monosynth features poll

[Tom Wiltshire]

I see. A bit of random gate bouncing adding a certain something to  
the leading edge of the envelope, I suppose.

There might be some delay issues too. I don't know, but I suspect  
that many uP-scanned keyboards don't respond that fast. The Prophet  
T8 (a top end instrument) scans its keyboard every millisecond, but  
only because it measures velocity. The 1980's wisdom seems to have  
been that anything under 20mS isn't perceptible and therefore doesn't  
matter. A simple gate direct from the keyboard is going to be faster  
to respond.
