[sdiy] super simple portamento / slide / glide / slew limiting circuit?

[nicolas]

Perhaps slightly less simple, but if you make a glide out of an LM13600 you can get voltage control of the glide rate and/or get S&H functionality as well.  You can possibly do it with just the single chip, but it would be easier to add a TL072 into the mix for buffering the output and the glide rate input.  The National data sheet shows something to get you started I think.  Here is another variation (doesn't include voltage controlled glide rate, but does do the S&H thing) http://electro-music.com/forum/viewtopic.php?t=41277
