I've run into a problem with my son's setup. He's got a system running
Fedora Core 1, with the Planet CCRMA 2.4.26-ll kernel and an M-Audio
Audiophile 2496, and for Christmas, I got him an M-Audio Radium 61
MIDI keyboard.
I've gotten past the firmware loading and USB MIDI configuration.
My problem is that if I use a program that allows me to choose the
interface, such as pd, I can see the MIDI signals come in when I use
MIDI interface #2.
When I use a program with no obvious way of choosing the MIDI interface
to use, such as ZynAddSubFX, I don't get any input from the Radium.
What I need to do here is disable the MIDI portion of the Audiophile,
so that Linux sees it strictly as a sound card, and sees the Radium as
the only MIDI device. This is where I am in over my head, as I've done
precious little with MIDI under Linux.
All pointers greatly appreciated!

This means that your MIDI in has been properly set up and can
now be connected to any application which should be driven by
the incoming MIDI signal.
Use aconnect or qjackctl or kaconnect to do so.
BTW: I do know nothing about pd so I cannot tell you how to
connect it to pd.

Ah, you've missed my mail goal here. I don't want to use the
Audiophile 24/96 MIDI interface - I don't want the system to even
see it, because I have a USB MIDI device (an M-Audio Radium keyboard)
that I want as the lone MIDI controller.
I think this is more a matter of not loading modules (snd-seq-midi?
snd-seq-midi-event?) for the Audiophile, and letting the USB module
do all the MIDI work, rather than setting something with aconnect, but
I certainly could be wrong!

The module snd-usb-audio handles MIDI as well as audio over
USB; when you rmmod snd-usb-audio, you will not be able to
get audio over USB.
Why do you want to disable the MIDI part of it? If you do not
need it, simply don't use it.

From my first post:
When I use a program with no obvious way of choosing the MIDI interface
to use, such as ZynAddSubFX, I don't get any input from the Radium.
Programs default to the first MIDI device, which is on the Audiophile,
and not all programs will easily allow one to change the input device.
Therefore, I want MIDI on the Audiophile completely invisible to the
OS, so that the Radium is the default device.
I may try not using USB at all, and connect the keyboard out MIDI
port to the Audiophile. It seems like a kludge, but it'll probably make
the default device what I want until I can find out how to disable the
MIDI on the Audiophile.

Why not make the Radium the default device by creating an
asoundrc file? Seems to be the much better solution to me.
Furthermore, try qjackctl to connect any MIDI input device to
Zyn.

I don't think Jack handles MIDI data. ZynAddSubFX does not have any
input ports visible in the qjackctl connection screen.

Definitely a brain fart on my part here - Jack DOES handle routing
MIDI, as long as you click on the MIDI tab in Qjackctl!
I have some joy here, listening to the computer play the synth controlled
by my keyboard!
A huge first step for me today, thanks all!

Thanks for the education :) This is my first foray into MIDI since
the days of my old CZ101 and my Amiga, so I have a lot of catching up
to do!!

Jack does not handle the MIDI data, but qjackctl does include
the possibility to drive the ALSA sequencer from within its
UI.
I for myself would be very pleased if every soundapp which
requires MIDI input had the possibility to select the MIDI
input from within the UI, but most do not have such a popup
or similar.

screen.
In qjackctl, choose connect => MIDI and you will be in
business, regardless if you'd like to use jack or not.
You can also use kaconnect or even aconnect in a shell to do
so.

Which programs are these, other than ZynAddSubFX? That's a bad bug,
that would render such programs unusuable to a professional. And
there's no excuse for it, it should be trivial to add support for
selecting the MIDI device to use.
Please report this bug to the author(s) of said program(s).

Joe,
What is in your modules configuration file? Does Fedora use
/etc/modprobe.conf or /etc/modules.conf? Anyway, you might try defining
these two devices with aliases that set them up so the Radium comes out
as MIDI #1 and Audiophile as #2, that way any application that by
default looks to interface 1 for input won't need to be patched in
through aconnect or qjackctrl to see the Radium.
I believe snd-usb-audio supports up to 8 devices, so you should be able
to define the 2 you are using to control the order in which they appear
on your system.
Something like:
alias snd-card-0 snd-usb-audio
# M-Audio Radium 61 (see *** below)
options snd-usb-audio vid=0x763 pid=0x1110 index=1
alias snd-card-1 snd-usb-audio
# M-Audio Audiophile 2496 (see *** below)
options snd-usb-audio vid=0x763 pid=0x1110 index=2
*** note - the vid and pid above are for my midisport 2x2, but if you "cat
/proc/bus/usb/devices" you will see the vid and pid for your two devices.

Note that there's nothing at all in modules.conf for the Radium keyboard.
It's simply a MIDI controlling keyboard, it makes no sound on its own, it
would be used simply to control soft synths on the PC.
I believe snd-usb-audio supports up to 8 devices, so
you should be able
to define the 2 you are using to control the order in which they appear
on your system.
I'll definitely take a look at this approach, as well as modifying an
asound file.

Anyway, you need the module snd-usb-audio for it, because this

there's no singular dedicated usb-midi-module to only handle
MIDI data (AFAIK in older ALSA versions usb audio and midi
have been two different modules, but this has changed).

Hi,
If I had a pci card that supports MIDI (and is working well under Linux)
and a USB midi keyboard, I would connect the keyboard's MIDI out to the
pci card's MIDI in, no need to add an extra device to the computer.
(Just an ac adapter to the midi keyboard)
Cheers,
Andres

With the USB connection, I don't even need a power adapter!
The trick here ended up using qjackctl to map the MIDI connections.
Thanks again to all for the pointers. The next step... matching the
faders to tracks in Ardour!
