Hello mates!
I'm useing Cubase SX 3.0 with some MIDI gear.
Somehow around ~30 min after being started, my MIDI setup starts to drift away.
Most certainly it's Cubase itself that's at fault. If restarted it's synced again for awhile.
Been useing MIDI since Atari ST times and never ran into this MIDI fault before. I'm not much of a Cubase parameter tweaker so perhaps the fault lies there...
Me mate got the same Cubase and uses it without problem, also with lots of MIDI gear.
Any of you PROs out there with a clue?
Much thankful for help!

Try enabling/disabling the Use system timestamp in the midi config in cubase. And try both the normal and the directx midi ports (if you have the dx ports to begin with...)
Which audiocard do you have? |

Audio card is RME 9636, very stable card.
MIDI is run through a MIDIsport USB 2x2 that always worked ok.
Using tx81z atm for bass and the midi delay is very sensitive to get the right rolling B-line.
Needs to be solid and don't want to "audio it".
I'll try your tip texmex, but will prolly just mess it up more! 
So many options...
Cheers |

If the midi latency is solid, you might have problem with the midi clock... checkout the midi timing settings in the cubase ie. check what kind of midi timing info the cubase sends to each midi port. unfortunately i don't remember where the config dialog can be found right now (not at home).
Hope you can figure things out. good luck. |

see if you your midi ports are [emulated] or standard.
if they're emulated, close cubase and check for a subfolder in your cubase root. there should be a pdf document about port filters. check the second page.
probably it helps to create a file called ignoreportfilters.(without fileextension) and drag it into your root folder of cubase.
be sure to check for previous installations of cubase eg. sx2. I once had problems because such a file existed from previous installations.
hopefully you're able to sort out these midi timing issues.

Can't seem to get it right. I tried a lot of different settings inside Cubase with not much luck.
Aslo tried the, ignoreportfilters., and put it in root dir. Not sure I did it right though.
I did install 3-4 nuendos and cubases ontop of each other without any HD cleaning (finding a good version) so it could very well be old folders causing it.
Since MIDI delay can be changed to fit the drifting it's a secondary problem... as opposed to DIN-sync. No way to fix a drifting TB i'm afraid, and makes it kind of useless 
Really killing my creativety this crap.
Any suggestions on what folder/s to clean or is Format C: the best solution?
Thanks mates!  |

well do a search in all the old folders (cubase & nuendo).
type in *.* and get a listing of all files in those folders. check for files without extension.
the file is either called "ignoreportfilter.*" or "enableemulated.*"
the file you gotta put into the root dir of your actual cubase is called "ignoreportfilter.*"
the pdf is located in the subfolder called midi port enabler. the solution is described on the second page.
hope you get it working

Ok... now tried both emulated and ignoreport. No noticable difference so far, but i'll keep tweaking. Perhaps it's worse then faulty midi ports.
bukboy.. acpi mode? I'd be glad to hear more.
I'm starting to doubt there's an easy way out of this nonsense...
For the Horde! |

acpi is irq sharing, used in win2000 and xp.
basically it improves irq assignement
on older windows versions you had something like 20 irq's to assign, even manually. with acpi this is history as it emulates irq assignement and theoretically ups the numbers of assignable irq's...
go to your device manager -> computer. there's either acpi computer or standard computer.
acpi is a good thing from my experience. lots of audio sites tell you to disable acpi. in practice I've had very bad results changing acpi to standard mode.
best thing to try out is a fresh install of xp with acpi disabled in bios. while installing xp you can change the mode. maybe google will spit out a step-by-step manual how to install it properly in standard mode.
that could be the reason for your timing problems.
before trying such stuff on your main harddrive you could try it on another partition/drive so you don't fuck up your main installation.
it's worth a try.

A clean install will happen as soon as I buy a new external HD. Next month I suppose.
Something I forgot to mention is that regardless if Cubase is being used or just turned on, it makes no difference. The drifting occurs either way.
I'll try dig into the acpi thing.
Thanks for taking your time fellas to help a unhappy camper!
Btw.. i'm swiss too  |
