Hello
It seems that you need jack in order to connect your usb-midi keyboard to
your application

a nice keyboard could be , I dont know if linux supports this keyboard
KORG nanoKEY 25-Key USB MIDI Controller Keyboard
$49.00

Thanks for all your efforts!
The last time I used a midi keyboard with a Mac (it was a
G3) it had to have a special midi interface and
then was just plug and play from there using
Finale as a program. In looking over your discussion below,
it looks like you did manage to get a midi keyboard to work
with the XO, but with great difficulty. Some questions...
Will it work with all of the TamTam Activities?
Is it likely that all midi keyboards would work?
Would it be possible to put the instructions into language
that the less technically inclined could easily follow to
get started on this?
Does anything have to be changed in the software/hardware
to make this easily used by teachers everywhere?
Do you know of any source of very simple, inexpensive midi
keyboards? No bells and whistles needed, they are already in
the XO in the TamTam Activities.
Could easier use of a midi keyboard be incorporated into a
change in the Sugar OS (like 9.1.0)?
Or is there an easy way to make the current set-up easier?
Thanks again for your interest and efforts!

On a more
disappointing note I found this ticket G1G1 tamtam
suite
should respond to
MIDI keyboard input from 10 months ago.
Closed.
Wont fix :-(

All wontfix
means is that they're waiting for someone with a
stronger
itch to scratch it ;)
i really have no idea how
such devices are normally presented to
the systems, but is it
possible that the keyboard is consists of
more than one USB device
(i.e., via a built-in hub) and that not
all the drivers are present
on the XO?
FWIW, The M-audio systems abide
by open midi specifications and are
platform-independent. I
don't know about the driver situation.
There is a program which can be
used to dump midi signals to
stdout.
It might be a good test as
it's very simple to configure and its
results are very clear, unlike
the audio programs you'll want to
use.
... and it's called??? Gah! ;-)
Just for reference, after connecting the USB
Midi keyboard amidi -l
gives me:
[EMAIL PROTECTED] ~]$ amidi -l
Dir DeviceName
IO hw:1,0,0 Keystation 49e MIDI 1
I'm not at an XO or my development
machine now, but looked around the
web to try to find some information to
help.
See:
http://www.4front-tech.com/pguide/midi.html
Will go read.
Does the system have a /dev/midi* when
you plug the device in?
Yep, I get a /dev/midi1
Do you see anything interesting in the
kernel logs returned with
dmesg?
Unfortunately our kernel configs
aren't online anywhere i can find...
but I'll check to see if it's
enabled. My guess would be not, but
perhaps I'm mistaken.
I'm trying to hack my way through
coding csound, but I've not had
much time
to play so far. A magic midi data
dumping tool would be a nice
shortcut to
test – FWIW, I can see my M-audio
correctly listed on the USB as an
available MIDI input device, but not
got any further yet.
Perhaps cat /dev/midi* if the file(s)
exist.
Fab, yes, cat/dev/midi1 gives me wild ascii
characters each time I
press a key, looks like both note and
velocity (this particular
keyboard doesn't emit pressure but I have
another one somewhere that
does), also other
