Interesting diverse set of uses.

For those that aren't interested in MIDI, but are building multiple 
units or already have a PSIM, you can use the hardware serial channels 
to slave together these units. The hardware serial provides a nice 
back-channel communications for these modules. I've used them to sync 
modules that have slightly differing clocks as well as some 
development work on bridging a program between two units when I needed 
more than 8 analog inputs or outputs. I've also used MIDI to send CC 
messages to my PAiA MIDI2CV to use those 8 analog outputs as well.

The display does add some panel constraints and complexity. I use mine 
always to display the name of the program.  After not using my synth 
for a day or two, I can never remember what program is loaded. If you 
are planning on doing any applications that have configurations or 
setup, a display is a must. I have two videos of the display on my 
site used as voltage level bars and an early sequencer user interface 
(which has since expanded in features).
