[linux-audio-user] Midi Woes

[Chip VanDan]

Okay, I know this question comes up way too often, but I've been
struggling with this for years and for some reason have never been
able to accomplish this, let alone grasp it.

I have a Yamaha Clavinova CLP930 that I wish to use as a MIDI
controller for my computer.  Basically I want to be able to play MIDI
events to things like Swami or amSynth through Jack from the
Clavinova.  I have an old-style MIDI cable, one with a joystick plug
on the end and a MIDI in and a MIDI out on the other end, which to the
best of my knowledge is hooked up properly.  My system is Fedora Core
3 with Planet CCRMA packages and the RDT (?) kernel working properly
as far as I know.  Now if there is a better distribution to be using
for this let me know because I plan on getting a new hard drive soon.
I've tried quite a variety and have recently settled on Fedora.

Now when I start Jack up I get an error that claims Jack wasn't able
to connect to the sequencer.  I can close Jack and if I type
/sbin/modprobe snd_seq, Jack won't give me this error.  I can also
load snd_mpu401uart, but this doesn't seem to have any effect.  When I
try to load snd_mpu401 it gives me an error as follows:

FATAL: Error inserting snd_mpu401
(/lib/modules/2.6.11-0.3.rdt.rhfc3.ccrma/updates/drivers/mpu401/snd-mpu401.ko):
No such device

I'm not quite sure what to do about that, but as it stands when I
start Jack now I only have the MIDI Through port listed in my
connections and I'm pretty sure that MPU401 is supposed to be listed.
I can play to all of my MIDI based programs (amSynth and Swami) with
the Virtual Keyboard, and I've tried using Kmidimon to see if any
events are coming across from the Clavinova, there's nothing.

As you can probably tell, I've struggled trying to figure this out for
a while, and still have barely anything.  I just don't get the right
feel off of Virtual Keyboard to actually perform.  If anybody could
explain this process I promise to make an in-depth howto because I
keep seeing these sorts of questions, but nobody seems to cover
everything (probably because there's a lot to cover).  For reference
purposes, because I know somebody will ask for it, I've added my
output of /sbin/lsmod at the bottom of this email.
