I finished my External Controls module that I interface to the CVS 
External IO connector and operate through I2C.  I put a schematic in 
the  Files>Hardware folder and a photo in my Photos>Dave Brown folder. 
The circuit only took 1 IC and a handful of resistors.

It's quite nice for user input.  It has a 12 key Velleman keypad and a 
single potentiometer for entering various parameters in programs.  I 
use it in my SuperSequencer program to enter the number of sequencer 
steps, MIDI GM program patch (e.g. Acoustic Piano ... Gunshot), and a 
MIDI offset to add to each note.
