Hello, and thank you for pointing out those URLs.  Again, these Linux 
apps are designed to run on PCs.  They might also work OK on a r-pi but 
you'd probably still have to hook up a display/monitor of appropriate 
screen size.  As I stated in a previous post my ideal would be an r-pi 
based device with the functionality and footprint of the "SD MiDi 
Controller" seen at www.sdmidicontroller.com but at much less cost. 
Sincerely,

Two points:

- you can run GUI programs on a headless RPI by enabling X11 forwarding
  on it provided that you logged in the the RPi from a system that is
  running a graphical X.11 server

- Adafruit sell 2.8" and 3.5" touch-sensitive TFT colour displays.
  Last time I looked they are round about £35. Rapid Electronics,
  http://www.rapidonline.com/ are Adafruit agents in the UK.

One of these may do what you want.

Hello, and those solutions diverge from my objective.  I want to 
construct a small (something you could throw into a backpack), 
fast-booting, stand-alone, wall wart/battery powered box.  It doesn't 
require a display of anything more than, say, a 2-line LCD display of 
about 25 characters/line to indicate the name of the MIDI file being 
played/recorded.  Sincerely,

you may need to investigate to see if there are any midi library's you 
can use to roll you own (python or perl should be good for this).
the pi gpio is easily capable of driving a 2x16 display

Take a look at the Adafruit displays before dismissing them entirely. 
They are uncased and designed to mount on an RPi: the result is the same 
shape as any of the RPis except the Pi zero and around twice the 
thickness: if fitted to a Pi zero the result will be about the size of 
the display and maybe 5-9mm thicker. In either case it should be easy 
enough to find a suitable plastic or metal box to enclose it. Run that 
lot off a Li-ion battery boxed with a USB power outlet, aka a 'portable 
phone charger'. 

Besides, using a graphical display may let you try a wider range of music 
playing/streaming programs.

That's not part of the spec.

The ``spec'' being it should look a lot like a walkman? A raspberry pi 
with a half-dozen buttons sticking out of the case and a 24 charactor lcd 
that uses impressivly little power with a play, rec, stop button and a way 
(button or wheel) to select the file and maybe midi channel?

Using timidty with parameters that works on 2ghz P4 systems over usb 
the lactency was unuseable for me (I am not a keyboardist. A good one 
could live with it (pipe organs can have the pipes up to 30 feet* or more 
from the keyboard => 30ms or more latency for the sound to get to the 
player.) Recording with a constand latancy would be OK but I don't trust 
it to be jitter-free.

I was using a GUI on either pidora or rasbian so it might have been better 
from a bare console, though I was also thinking of using an arduino to 
gather and timestamp the midi messages. With the messages time-stamped 
they can leasurly be sent to the pi or other host.

Don't remember if I plugged ccrma satellite in this discussion:

easier would be to installa vncserver on the rpi, and connect to it using a remote desktop application.

Actually no it isn't (assuming you are connecting from another Linux box)
X11 forwarding is normally enabled  out of the box :-)

Please, please, please, I'm begging you, please do this.  It's the only 
way
people learn quickly.  Being nice is great, but nothing works faster than
a cold shower of public humiliation :-)

Much better quality and faster than VNC is RDP, which means you can also 
access the RPI's desktop from PC's using the remote desktop client.

Install x11vnc (as it uses the current logged in session rather than 
creating a new session like some other VNC clients), then install XRDP. 
You need to set both to start as daemons if you want to be able to log 
in straight after booting up, rather than having to open an ssh shell 
and start them first.

	But why add all the layers when you're already using a network
based display system, ssh -X rpi.whatever and run anything you like in its
own window to have the display traffic in an encrypted tunnel or just use
xhost to allow direct access to the X server from the Pi. This approach
worked fine 25 years ago or so using 10Mbps shared coax networks - it works
even better today using gigabit switched networks.
