[sdiy] polyphonic glide behavior

What about gliding up or down to all notes from a fixed interval away, no
matter what note was played before.

So, for example, say you play C-E-G.  If the glide is set to "Up a fifth"
then this chord starts out as G-B-D below, and all the notes glide up at the
same rate, maintaining the tuning during the glide.

That's probably how I'd do it.  It kinda sounds like portamento (or maybe
more like slide guitar), and it seems more musical than some random

Alternatively, only the lowest (or highest) notes are truly portamentoed,
and all the other notes glide up or down by the same amount at the same
rate.  That seems doable.

I can answer only from the players point of view:  there is no "right" 
kind of glide. Simply both variations are valid options, and depending on
which effect you want to achieve (short and smooth like changing the note on
a violin or guitar, or random swirling to make it "sound like a
synth") I would choose the one or the other. I remember my Jupiter 6 with
Europa-extension which provided various voice allocation algorithms. Each of
them caused a different glide, and each of them was usable and desirable
under certain aspects.
