3538i + logic 5.5.1 causes a buffer effect

resetor · Nov 27, 2005, 06:51 AM

Last night I installed the 3538i and now I'm having problems in Logic Audio Platinum 5.5.1: Whenever I tweak something in Logic, there's this kind of 'buffer' effect, a very short loop repeating from wave buffer apparently. This also happens when windows does something on the background. And when it gets real bad, I get these messages:

"Error while trying to synchronize Audio and Midi.
Sample Rate 42499 recognized"

or just:

"Error while trying to synchronize Audio and Midi"

On some songs there's also crackles and pops even if the song uses only about 50% of processor. I have the same latency setting of 21.33ms which worked just fine with version 3537(and earlier) of KX drivers and I have tried different sync modes too, but to no avail.

Anyone have any ideas? I'm running Windows XP PRO with AMD XP2100+. I can of course revert to 3537 if nothing helps, but...

Thanks in advance,

Riku

try changing the mode of the ASIO driver

i was having problems in logic earlier today that were fixed by changing the mode

What exactly do you mean by 'changing the mode of asio'?

In Logic I can choose between 'ASIO directx full duplex' and 'KX ASIO', but only the latter works. I think I had the clock source set to 'internal' before, but with the new drivers the only choice is "KX internal". Could that be the difference?

I have tried with different latency / buffer settings, but none of it makes any difference at all. It seems I have to install 3537.

I now also got this error:
-----
Error while trying to synchronize Audio And MIDI.
Sample Rate 41310 recognized.
Check conflict between Logic Platinum and external device.

Somehow it seems that other processes take priority to KX driver or something. They interrupt the communication between sequencer and the driver, but this is of course just huge quesswork. I wouldn't know...

It seems that even Winamp's playback is being interrupted for example when it's minimized and I restore the player window. So, it seems there's somekind of conflict between KX driver and possibly display driver. I know my card has it's own IRQ so that can't be it. And as I said, everything was fine with the older version of the driver. Weird stuff...

Just to make it sure, I re-installed version 3537 and yes, it worked as supposed to, then uninstalled it and installed 3538i again, but it's not working any better than before so I quess I just have to use 3537 for the time being...
