Nice big system!

cvproc is a CV processor. It is used to invert, shift (relative to 
0V), amplify and attentuate CV (control Voltage) signals.

>any ideas for the 'ringbr' in particular?

Ring modulator with separate AC and DC coupled inputs.
Two inputs "X" and "Y" are summed and divided, and the result shows 
up at the "Z" output. The module is a dual module, with two ring 
modulators.

ExtInp is a module for turning external signals (microphones, 
guitars, music etc.) into signals that can be used with the Formant 
(control signals and gate signals)

sequ-adsr looks like a "COM" module; that is; a VCA with inputs from 
an ADSR and a sequencer?

All these are standard modules from book I and II, but with some 
twists as to the front panels.
