Korg Forums

I've found a rather nasty bug in C5. The application won't launch if my Korg PA2xpro is connected via USB. Everytime the Korg is powered on and I then start C5, it crashes with an error signature of "Modname d52asio.dll Modver 2.1.0.0. Offset 0000397b.

This is repeatable ever time. If I remove the Korg USB, then C5 starts normally. This problem never existed with C4 and SX3 which I still use. I've reinstalled C5 and the Korg usb midi driver but the result is always the same. The workaround is that I will have to resort to using midi cables again until it's fixed. I'm pretty sure this isn't a problem with Korg but I thought I'd just make you guys aware.

Is this on Mac or PC?

PC on XP service pack 2

Then i'd have to give up on my PA800.

I suspect the "fault" may be a problem or interaction with the Korg MIDI over USB driver. I think there is a Microsoft MIDI over USB driver that is more stable.

Hi Rob,

Do you have any further info on the Microsoft Midi USB driver? I've searched the Microsoft downloads but can't find anything listed.

The Microsoft USb MIDI driver is a standard supported feature and if you plug the kcable in to your keyboard and the keyboard is generating MIDI clocks, then the USB driver should install automatically.

However with Windoze's ubiquity there are always "gotchas", and the thread below reveals that many people have been struggling, and there is a registry hack that seems to solve one particular issue prevalent on Core 2 Duo machines:

The funny thing is that I have a Core 2 Duo desktop machine running the Microsoft USB Midi driver with no problems and my M3 on the other end. I never had to do any registry hacks. I de-installed the Korg USB MIDI driver after I experienced a number of crashes reporting a problem with that device driver, and the Microsoft one was auto-installed in its place as soon as I plugged the M3 into the other end of the cable (with MIDI clock master on the M3).

Best regards,

Rob,

You're a star. By using the windows Midi USB driver, Cubase 5 starts fine and there are no issues.
I didn't need to go editing the registry as the Microsoft driver worked first time.

Many thanks for you help (as always)

Hi Simon,

I'm glad it worked for you. Like I said, I encountered many stability issues in the Korg MIDI over USB driver. I don't know why they confuse everyone with their own version when the Microsoft one works so well.

Best regards,

Hi Rob,

It didn't help because i didn't even know Microsoft had a native Midi USB driver that would work with the PA series. I thought it was a bit to specialized for Microsoft. But you live and learn.

It's not often Microsoft come to the rescue over the OEMs
