[sdiy] Starting my ASM-1

[harry]

The neat thing is I SWORE the fvcking thing could not work... that the
glide would stop as soon as you remove you finger (stuck halfway there?)

So I simulated it... and I WAS WRONG... it works beautifully.

For a non-scanning keyboard... I'd probably use the CD4532 priority encoder
to get low note priority. latch a valid output... and use a DAC... these days.

OTOH I sibscribe to the MIDI keyboard and CV converter... best way IMHO

(why do so many people capitalize IMHO... kind of an oxymoron ain't it ???)
