Subject: 700

Hello All -

A little while ago there was some discussion about the 700 in audio
mode. Folks were noticing a 'click' on switching. I went through
this when I first got the module, and as I remember the thing to be
aware of is that even though there is a brief silence inserted while
switching, if the waveforms are out of sync, a click will happen.
Imagine a sine wave that gets switched as it is heading up, while the
sine wave being switched in is heading down. The silence is brief so
what you get is:

|\
| \
| \
| \
| \
------

I have a better picture of this, if anyone wants to see it I'll post
it in the Files section.

This module doesn't morph one wave into another: it simply switches
between the two with a brief silence in the middle. Syncing helps as
does envelope tweaking. It takes a bit of fiddling but you can get
smotth transitions. Note that usues different waveforms for A and B
is more difficult.
