kx.sys crashes during MIDI-Playing

r.hawke · Jan 8, 2005, 04:23 PM

Hi!

Recently once in a while (about every 10th song i listen to) kx.sys crashes and i get a Blue Window:

Driver_IRQL_NOT_LESS_OR_EQUAL

Address: BFD72558 base at BFD49000 Date Stamp 40313a39 - kx.sys

After that all i can do is restart my computer.

I already thought that my soundfont caused it to crash, but i tried an other one and still had the problem.

Hope you will be able to fix that - in case u need more info: just tell me what to do. (sending log files, installing debuging software ...)

is you soundcard sharing an IRQ with any thing else?

r.hawke · Jan 9, 2005, 10:40 AM

i am running win 2k where irq sharing is basically enabled:

http://support.microsoft.com/default...;EN-US;q252420

so all my PCI-Devices plus some onboard devices run on IRQ 9

PCI:

SB Live Value
NEC 1394
Realtek Network Card
ITE IT 8212 IDE Controller

Onboard:
VIA USB controller
VIA Vinyl AC 97 (second soundcard)

to be honest i activated the onboard card just 2 month ago. But i'm not sure how much i've been playing midis in that time.

i hope that this is not the problem, since i need the second device for my Headset

is there a way to reproduce this issue by playing back particular midi file? or it is comletely random? if yes, please try to find the exact MIDI sequence that causes a crash. also, check if you are using built-in synth (kX Synth) or Microsoft synth

ok, I'm using kX Synth 1 directly (meaning that the programm can choose the device itself - instead of using the MIDI Mapper and then selecting kX Synth 1 in the Windows Settings)

It is not a special sequence. Actually it must have something to do with the initinalization, since the error occurs when i load a new song.

Sometimes the error comes right on the first song i try to play. Sometimes i can play about 7 to 8 songs in a row until the pc crashes. And it is no specific file either. If I restart I can load the midi-file that had just crashed before without a problem.

And thanx for the help!

Just for the Record. I'm using VanBasco Karaoke Player to playback my Midis.

There's an issue with Windows 2000 of that problem occuring when playing MIDI and connected to the internet at the same time!

r.hawke · Jul 9, 2005, 07:24 PM

thanx for the info

however i found a workaround

just use midi-mapper instead of the kx device and select the kx device as the default windows midi playback device in the control panel.

I have the same problems when playing MIDI via VanBasco's MIDI player.
[Wink2k SP4, kx drivers 3537]

The workaround is good, but does anyone know the cause of this issue?
