MIDI Volume Bursts

tim57var · Post by **tim57var** » Sat Sep 01, 2007 2:23 pm

I'm getting some random bursts in MIDI volume (it could be expression CC#11 or Volume CC#7) on my plug-in instruments. I'll be working along and things will jump up radically in vol for about a bar or so. It's very intermittent, and happens mostly while I'm recoding a MIDI track, although sometimes happens just on playback. I never had this problem pre-Intel. Anyone have this happen, or suggestions??

This problem used to happen to a lot of people on the G5's. I never had much problem with it (I'd say none, but I don't remember that clearly), and I attributed it to certain drivers. I used a particular set of old MOTU drivers for many years, and they were trouble-free, but they did not work with the later G5 models.

Moving to Intel has brought the problem to me as well. Unfortunately, this is one of those intermittent things, and if I recall correctly, MOTU's standard response has been "we cannot recreate the problem," even though everyone and his dog and cat has called or filled out a tech note and complained about it.

Maybe we need to start a petition.

You mean; MOTU's standard lie.

Yeah-

I posted something similar last week. I called MOTU about what I call MIDI bursts. Not volume but in my case it sounds like MIDI choking resulting in MIDI playback haulting briefly and than a big bang of MIDI drums and it will contuinue normally.

MOTU told me they "never heard of this before",.... such a crock.

It's amazing how Magic Dave never contributes to these type posts?

Well, I was one of many 'Cornies who were contacted as part of an effort to nail the problem down.
Rich Montero was seeking user sequences that were known to manifest the issue in a last ditch attempt to recreate the bug.
Obviously, they'd had no luck.

Perhaps the individual you spoke with hadn't heard of the issue.
He was probably a new/young punk on the block, and I doubt his was the definitive, official view of MOTU.

Magic Dave contributes an awful lot of valuable information.
Bug issues aren't his thing, nor should they be.
Explaining techniques and procedures within DP, as well as audio and recording issues of a more general nature, seem to be his strengths, and he shares this knowledge unselfishly, IMHO.

I've also had this problem now that I use Kontakt2 a lot.

Had no idea it's been bothering people for such a long time. MOTU will soon hear from me too.

Monkey,

You are right Magic D has helped me a lot,.
what I really meant was, it seems that he is the lone voice of MOTU here on the forum,? mayabe not,..? I'm not so sure?
He is also the power user of all power users.
I guarantee he has seen, heard or perhaps experienced these MIDI weird issues himself.

I guess it didn't come out right, my frustration is in the lack acknowledgement from MOTU.
hope that makes sense?

Peter

I get these bursts regularly as well - even playing back audio tracks - the whole sequnce just increases in volume for about a bar or so, very randomly.

ditto - I get these and it does seem random...

Just for the record, I get 'em too in MIDI tracks.. totally random.. it's been one of those bugs I've just learned to live with though. I pick and choose my battles with MOTU....

Does this only occur during playback and not in bounced tracks? For instance when you've done all the work and is about to burn your CD.

I'm gettin' it too. Can't nail down any conditions which make it more or less prevalent. A minor nusiance. Once I get into final mixdowns, it's going to be a major pain.

Just to express myself a little more clearly:
What I'm wondering is if the final mixdown contains those volume defects. In that case it's a disaster.

Of course it does, Pete!

Sorry if I came across as an old fuddy duddy.

I'm always careful however of over reaction, speculation and the like's effect on less experienced and indeed potential DP users.
Just tryin' to keep it real, put myself in MOTU's shoes and encourage patience.
MOTU always delivers; the mail may well be late, but at least it arrives.

Don't know, snobby.

The fact that nobody here sees any rhyme or reason to the bug should be proof enough of the difficulty MOTU's had exposing it.
As I said, 'Cornies were consulted, but as to whether anyone was able to produce a file that guaranteed the problem, I don't know.
We can only hope MOTU's nailed it down or is well on the way.

I don't know whether or not these bursts make it through the bounce.
Some 'Cornies reverted to realtime mix creation a couple of months back due to bounce issues, so I'd do this too just to be safe.
I mean, by the time one's put all that blood, sweat, tears and time into a project, one shouldn't have too much difficulty savouring the mixdown.

Yes, let's hope so. Somehow it shouldn't be such a big problem. I'm not into programming. But if I'm to guess, it has to do with event chasing.
