I just built it.  I did a Schaeffer panel with MIDI input and output.
I knew the PSIM could support MIDI and wanted everything possible on
a single panel.  In a previous post I posted a link to my Schaeffer
file and a .jpg of the panel layout.  My panel is due tomorrow!

I wanted to verify the MIDI interface before I wired up the panel so
I just made one.  MIDI is just 8 bit serial with a start/stop bit
which the PSIM hardware supports.  MIDI utilizes a 'current'
interface with optical isolation so it just takes a few components to
do the conversion.

The MIDI output schematics are already posted on the web.  I believe
Brice will be posting a schematic sometime and possibly offering a
complete interface if there is sufficient interest.
