[sdiy] A6 Voice Signal Path Charts

[Mike Peake]

It's odd that we never released the signal path
charts to the A6 analog section(s). On this,
nearly its birthday again (counting from when
it shipped), here are the signal schemos..

These may not be the most recent versions (note
the two switches for selecting hard and soft
sync, versus having a null node and one switch).

The gist is there, however. Note the simultaneously
available analog noise and audio-rate FM paths.

The initial voice included diode-based signal shaping,
etc. but things like that were excluded in the
interest of chip size (and actually finishing
the instrument!)
