Clicks and Pops with MOTU 2408

wgallant wrote on 8/10/1999, 4:20 PM
I am currently testing the Vegas Pro Demo and loaded it up
on a PII-350/128MB RAM/UDMA IDE drive strictly for audio.

All tracks are being recorded from DA-88 through a MOTU
2408 to the hard drive.

Each track exhibits periodic clicks and pops when recording
with Vegas Pro. Even recording only one track exhibits the
same problem.

There are no clicks and pops when recording the exact same
audio material with CuBase VST/24.

I suspect a driver issue between the MOTU 2408 and Vegas
Pro?

Is this a known issue or am I barking up the wrong tree?

Talking to Customer Service yesterday to get the serial
number and they mentioned that some of the guys at SF were
using the MOTU 2408 sucessfully with Vegas Pro.

Has anyone found a combination of buffers and settings that
will allow pop and click free audio using the MOTU 2408
with Vegas Pro?

I would love to purchase the program immediately, find it
superior to anything else on the market GUI wise, but if it
won't work with my equipment I am going to have to pass for
now.

Any information/tips to get this issue ironed out are
appreciated. Thanks!

Will ...

Will, you need to check your clock source in the motu console; the
clock should be set to 2408. internal. If you were to "fly" the
audio from a dat using SPDIF you need to change it to SPDIF. Then
change it back to PCI Internal on playback. The MOTU Folks will be
able to handle these things for you.

Hi Brett,

Thanks for the reply but I should have mentioned that the clock
source is set correctly. CuBase would not have recorded correctly if
the clock source had been incorrect.

AAMOF, I've tried both the 2408 and DA-88's as word clock master to
no avail.

Still got the click and pops when recording with Vegas Pro.

I would really like to hear from SF on this issue. There are only
four days left on the evaluation clock and program is sitting there
virtually useless.

Hi Peter,

Thanks for the response. I would hope that it would have more to do
with the MOTU to the hard drive than with the DA-88's. But then
again, the differences between Lightpipe and TDIF interfaces on the
MOTU may be huge.

Waiting to hear back, and hoping I've got some time left to evaluate
the program when I do.

In any event, thanks again,
Willg

It should not be a DA-88 issue. It is an interaction between Vegas
and the 2408.

I will do my best to get this resolved in time for you to make a
reasonable evaluation.

Thanks

I am also working with the 2408 in combination with Vegas Pro. I
could not find any problems. It works perfectly. Had all kinds of
connections (spdif, adif) and both master/slave situations. The
buffer sizes I use are standard (1024).

I have tried every possible combination - short of using DA-88 - with
the 2408 and have no problem. I have streamed in 16 tracks (8 stereo)
from ADAT sources with no problems. All recorded media is glitch free.

Will:
Do you know whether the 2408 is sharing and IRQ with any other
hardware? Is the PCI card in a bus master slot?

Are you attempting any type of sync (MTC) based transfers?

I am still looking at this, but so far I have had no problems.

Hi Peter,

The machine is a dedicated DAW, not on a network, and with no
resource conflicts apparent. We are careful to keep it by free of
anything that is not audio related.

PII-350; 128MB RAM;4GB IDE UDMA drive for OS/Programs, 8GB IDE UDMA
drive for Audio only, 13 GB IDE UDMA drive(s) in docking bay for
archiving; Advansys SCSI controller for CD Architect's CD-ROM drive
and Jaz Drive; (I believe that I have bus mastering turned off, but
will check)Pardon me for being hazy, but the DAW in question is in
the studio, miles from here, sans connection to the Internet or
telephone.

I am not attempting to sync (that will be the next test), just to
record to the hard drives using the TDIF I/O on the MOTU 2408. Both
DA-88's are in "Digital Output", I have tried using both the DA-88/SY-
88 and the MOTU as Word Clock master with no difference. Playback of
material (recorded using the same settings in CuBase VST/24)in Vegas
is flawless.

Could I be using the wrong driver for the MOTU 2408/Vegas
combination? I know there is an ASIO driver for Cubase VST/24 and I
am not aware of loading another driver in the change over. Would
Vegas work at all if the wrong driver is loaded?

Thanks for your efforts. I really like the program and would like to
get this sorted out prior to purchase. Unfortunately, I am all too
keenly aware of programs like this running fine on one machine and
exhibiting problems on another.

Thank you again!

Willg

Axel,

Thanks for the feedback. I am starting to think that the problem may
be a short between the keyboard and the chair and that I may be
somehow using the MOTU 2408 ASIO driver for Cubase?

I don't even know if that is possible?

Will:

I wish I had an answer for you. What sample rate are you recording
at? (I am grabbing at straws now.)

Q: Does Vegas record correctly when using the analog inputs on the
2408?

The ASIO drivers do not interact with Vegas - unless Cubase is
running, which would prevent Vegas from using the hardware. If there
was a problem with the drivers, we would not be able to playback
either.

I am still attempting to repro.

Thanks
Peter

Hello Peter,

I am recording at 48KHz off the DA-88s.

I will try and use the analog inputs this evening to see if the
clicks and pops persist with them and post the outcome.

Actually, I had another unsettling problem this morning. A *.veg file
with 10 mono tracks(48k/24 bit .wav files that were recorded in
Cubase and then opened with Vegas, including some extensive edits
that I was trying out)that played back perfectly last week would not
play correctly today.

Some tracks speeded up, others slowed down, and they were all
generally out of sync. I finally managed to get them to settle down
by increasing the playback buffer to ".90". The meters was hitting
about 24% max even during the worst of the problem.

I find it strange that last week the buffer was set at ".25" with no
problems and yet it would not perform at that setting at all today.

The audio hard drive does not have files kept on it and it was
defragged before use, just as it was last week.

I have no problem kicking the RAM from 128 to 256MB in this machine
if that is a factor and it would help Vegas' performance?

On the plus side, I performed some edits across multiple rhythm
tracks with ease, edits that would normally take hours of trial and
error. Would be nice to get this program peforming consistently on
this machine as it could be a real time $aver.

I am not ready to give up yet, but there does seeem to be a
performance, as well as emotional, roller coaster with this program.

Here's hoping,
Willg

Will,

although I don't know if you've already tested transferring the
signal analog from the Da-88 to the 2408 I would exspect it to work
perfectly. I think Peter's advice could be the final hint to find out
what basically the problem is. I might be wrong, but in another forum
(Mackie d8b) there were long discussions going on trying to get over
the problems with digital Xfer between the DA-88 and the 2408. If I
am right there is a clock issue between the DA-88's and Motu's TDif
interface. I read something like "the clock signal of the 2408 is
inverted by 270° to the DA-88's". The only thing I know for sure is
that there is an issue between Mackies d8b digtal I/O-card (Tdif &
Adif) and the DA-88. While the Adif works fine, the problem with the
Tdif persists.
As I mentioned before I am using the same hardware as you do without
any clicks and pops - but: I am using the the Adif interface.

Hope this helps,

Hi Axel,

I didn't get a chance to try the analog last night, but am heading
out to the studio to do just that this morning.

While I understand your theory about the TDIF I/O between the DA-88
and the MOTU, consider the fact that CuBase records quite nicely and
exhibits no clicks or pops at all with the DA-88/MOTU 2408
combination. :)

But then again, and as I understand it, Cubase is using a totally
different driver for the MOTU 2408 then Vegas is. Am I correct?

If so, then I would assume that the difference is either driver
related, or software related (the latter including any configuration
issues that may be causing the problem).

Either one will kill my hopes of using Vegas reliably for the time
being.

I'll post my results on the analog input recording test this
afternoon.

Still hoping,

Willg

Peter,

I apologize.

It appears that the "clicks and pops" problem was a 'short between
the keyboard and the chair' all along. I spent the better part of
four hours of downtime in the studio this afternoon determined to see
if I could find any configuration issues that were causing the
problem (I still got them recording using the analog inputs)and lo
and behold, I found it.

I was causing Vegas to record to the wrong hard drive! I set it once
thinking I'd made a more or less permanent selection. Obviously this
box does not have enough juice all around to run the program on the
same hard drive that it records to. A bad practice and rookie mistake
in any event.

Solution: make sure that "File|Properties|Audio|Start All New
Projects With These Settings" is enabled and make sure that the
recording drive is properly (and permanently) selected.

Once that was sorted out, the clicks and pops disappeared completely.

Suggestion: Consider a screen that pops up when you first arm a track
in a new project asking for a drive\directory path. It would be a
nice touch to be able to choose a drive and directory and have the
directory created if it doesn't exist at that time.

What did increase throughout the afternoon, however, was the
frequency of blue screens with an "Exception OE in vxd_MOTK*******"
when attempting to arm a track. It was the first time I've seen this
and rebooting seemed to cure it for the most part, but still a
niggling issue.

At any rate, I feel more comfortable now that the program can be made
to function in our environment, BUT, I still think you guys may have
some issues with the MOTU 2408 that aren't ironed out yet. I would be
interested to know if that is indeed the case?

Thanks for your efforts with the "clicks and pops". I am glad that it
was such a simple solution and although I feel foolish to have caused
such a long thread, maybe someone else can benefit from same.

Regards,
Willg

I am glad you discovered this as the problem. I wish I would have
thought of it. We are reviewing the "record to" approach along with
all file/project management issues.

As far as the blue screen error, these are driver issues. Vegas - and
all SF apps - call the hardware legally. If the driver cannot handle
the calls, then the blue screen error is very possible. Not that I
will ignore this: I will try to repro and discuss the issue with
MOTU.

Drivers are always our biggest nightmare....

Thanks
Peter

Peter,

I am going back to double check the reproducibility if the following
again today, but I am fairly certain that if I make sure Vegas is:

1. Configured to record "16 bit".

OR

2. First open a 24 bit wave file into a track in the new project
BEFORE attempting to arm the first track with Vegas configured for 24
bit.

... the "blue screens" do not happen.

IOW, this issue seems to revolve around the setup to record 24 bit
when using the MOTU 2408(at least for our setup through the TDIF
input).

The "blue screen", while recoverable from with any keystroke, insures
that the MOTU contol panel is bolloxed up and unusable, necessitating
a reboot.

Hope this helps sussing out the driver issue.

Regards,
Willg
