a) OK it's settled! Voices grouped ∗vertically∗, with CV on the bottom. Moe, please mock it up.

b) Looking at the MIDI jack: the thick MOTM panel is causing an issue. The standard pcb mounted
MIDI connector assumes a 0.062 thick panel. When the connector is butted-up to such a panel and
the DIN cable plugged in, this allows the outer plastic molded portion not to touch the front
panel (by about 0.025). The inner metal 'shell' goes all the way into the connector.

Now, with the 0.125 thick panels, you have to have a large hole cut that is bigger than the
outside dimension of the "fattest cable you ever hope to come across". I measured all my MIDI
cables, the largest one was about 0.665 outside diameter. This means a 0.700 min hole to allow
for 'slop'. Well, I think that is too big as it looks a little strange with this giant hole where
you can see the pc board slightly.

So, I'm proposing using a Switchcraft or Neutrik panel-mount DIN. The Switchcraft one has silver
(nickel-plated brass) flanges. It's part number 57GB5F. I haven't looked at the Neutrik, maybe
they have a black one. This does mean 2 'exposed' black screw heads along with the flange.

It is about the same labor. The reason is that the pcb mounted one needed a support bracket and
PEM threaded stud. The panel mounted one I have to solder wires (yuck). So far as cost/labor it's
even.

But, it 100% removes the "my DIN cable won't plug in!" issue, and I think it will be better
overall. Opinions?
