MOTM

This looks great!  A few things...

1) I may have missed this, if I did, my apologies...  Since there is no
Midi-Thru on the front of either this or the 600, to avoid a Midi distrib
box, can the Midi-In jack in front be used at the same time as the Midi-Thru
in bacK?  That way one can connect the Midi-Thru connection (in back) to the
Midi In jack in back of the 600.

2) Is there a way to "daisy chain" the Ext Clock signal to other modules
from the rear of the modules?

3) Is there any reason that the buttons on the 600 series are not
standardized?

4) I vote for the "horizontal" layout.
