Hello, you all!
I'm having some trouble trying to use MIDI with my external keyboard
(Yamaha PSR 620, well, not a big kb, but it's what I have for now...)
The system sudenly freezes when I try to start or stop a song in a
sequencer software. That happend with Muse and with Rosegarden, so I
think that is not a software problem. I have an Asus motherboard,
especifically an A7N8X-X, with the nForce2 chipset and embedded AC97
for audio. I am using the intel8x0 module and MIDI is working, at
least for some time. The motherboard didn't come with the (in)famous
joystick port, so I bought a homemade connector to put in the back of
my box. It is working relatively well and I don't know if this is the
guilt or not...
I searched the net for this behaviour but didn't have much luck. Has
anyone experienced this kind of problem? I mean, is there anyone who
uses MIDI with the nForce2 successfully? It is freezing constantly in
my system and the only way to go on is to reset the computer. I think
that the the one to blame is the chipset but would like to hear some
advices and experiences from others owners of this hardware.
Thanks in advance and best my reagards.

Does MIDI work inter-process, like from Rosegarden to Hydrogen or AMS or
some other softsynth? If so, then I'd say your homemade interface may be
the culprit. I recommend getting a real MIDI interface -- an M-Audio
2496 card is only $99 most places and is at least semi-pro in terms of
its quality and I have had fantastic results with its MIDI interface.

Hi Brett,
Well, I used the Aeolus organ softsynth, from Fonz Adriansen, with the
virtual keyboard and it worked very well. I don't remember having any
freeze with this setup. I will try to push this a little more to see
if I can freeze my system with it. But with my external interface, it
freezes very soon.
Thanks for the advice of the M-Audio. I will try to find some here in
Brazil. I hope I can find one easily, though I fear that is not the
case... But thank you very much!

They have a Latin American site:
http://la.m-audio.com/
You should be able to find a local distributor.

The latin web site doesn't have any information about resellers in
Brazil. And my budget is a little restricted to purchase that board
for now. :-) But I'll continue looking for some second hand audio
board (maybe a SoundBlaster Live), and trying to use my system the way
it is...
I thank you very much for your attention and fast responses.

Yes, there is a brazilian version of ebay, called MercadoLivre and I
didn't found the board there. But I'll go on trying...
Thank you!

Hi Denis. If you are going to try to find an Audigy live. Try to find one that
uses the emu10k1 driver. These have a wavetable and you will be able to load
soundfonts onto the card. This makes it all a bit easier to use Rosegarden,
Kmid,etc. These Audigy live cards are not expensive. Perhaps $25 US. Nigel.

Does it work when you try to play a .mid file with aplaymidi?
What ALSA version are you using?
How did you configure the snd-mpu401 driver?
What are the contents of /proc/interrupts?

Hi, Clemens.
aplaymidi is working very well... I could play lots of midi files, and
some of them very large and it didn't freeze. My alsa version is
1.0.9a, the MPU401 driver has no extra parameter (just load it in
startup time) and the contents of /proc/interrupts are:
CPU0
0: 1648190 IO-APIC-edge timer
1: 1813 IO-APIC-edge i8042
7: 0 IO-APIC-edge parport0
8: 0 IO-APIC-edge rtc
9: 0 IO-APIC-level acpi
10: 5803 IO-APIC-edge MPU401 UART
12: 66422 IO-APIC-edge i8042
14: 40898 IO-APIC-edge ide0
15: 14637 IO-APIC-edge ide1
19: 139242 IO-APIC-level nvidia
20: 0 IO-APIC-level ohci_hcd:usb3
21: 147820 IO-APIC-level ohci_hcd:usb2, NVidia nForce2
22: 196551 IO-APIC-level ehci_hcd:usb1, eth0
NMI: 0
LOC: 1648075
ERR: 0
MIS: 0
It seems that the MPU401 is where it should be, though I don't know
what this /proc/interrputs is for... :-) The mpu401 driver is getting
the right IRQ (10) and memory address (0x330), as says
/proc/asound/cards. The kernel is 2.6.12-gentoo-r10.
My .asoundrc is very simple, just like the first example in the alsa site.
I'll keep doing more experiments and inform you if some different happens.
Thank you for your attention.

Then it's probably not a hardware problem.
Does the "rtc" interrupt count increase when you play in Muse/
Rosegarden? If yes, try adding the line
alias snd-timer-1 off
to your /etc/modprobe.conf, and reboot. (This should disable the RTC
interrupt).

Hello, Clemens.
Thank you for your suggestion. I've found the problem last night when
I killed the artsd. I used to start the artsd with jack right on the
startup sequence to make kde use the soundcard together with the other
sound applications (muse, ardour, etc). So, when I unloaded artsd, all
worked very well. I recorded some tests and played it without any
quirks. Then, I changed my script to not load artsd after jack.
And I observed the rtc interrupt while playing with muse, but it keept
on 0. So, I think that the setup is correct.
Thanks again for your kind attention and my best regards.
