Yamaha DM2000 MTC problem

Hi, i want to know if is there anyone that knows how to resolv this little problem.
I have a Yamaha DM2000 v 1.14 and a Mackie SDR 24/96. I have the 2 machines connected
digitally using 24 adat channels. The Sdr is the slave machine and the dm2000 the master,
sending the sync signal by adat format (sorry for my english), The SDR is sending the MTC
code by 1 midi cable to the "mtc in" of the dm2000. All is working fine, except that in
the Optional meter of the console i see the time code of the sdr withouth problems when
i'm playing , but when i try to use the jog wheel or the ff or rew buttons the time code
froze. I need to press stop again to display again the proper time code.
I'll
hope that the explanation is large enough : ) maybe is a limitation of the pre V2 console
or something? I can't find the answer anywhere else.
Thanks

I'm a little confused. If the DM2000 is the master then why do you need to send MTC from
the SDR to the DM2000? Maybe I'm missing something because I don't use either of these but
I would have thought that just using the ADAT sync connection would be sufficient to send
all the machine control and timing information you need to the SDR. Cheers. James.

I'm taking a guess here that you use the DM2000 as the controller to send PLAY and REWIND
etc. commands to the SDR, and the MTC of the SDR is telling the DM2000 where abouts in the
song you are?
I'm not sure if you really have a problem! I don't think the
DM2000 has a chance to pick up the correct MTC if the MTC is rewinding or fast
forwarding?
Next time I'll look at how the old 02R reacts to fast moving MTC.
I'm jealous of your desk! And your English is better than some "native" speakers
do on these forums!
Cheers,
Davy

Thanks for the answers.
The first thing (for James ) is that is not
possible to control the sdr from the adat sync code only. You need to connect the serial 9
pin cable out of the dm2000 or the midi connections. All the midi machine control codes
are sends by this connectors only.
Maybe is possible that the dm2000 is unable to
show the proper timecode when is doing transport controls.? Like LimeZX9 told
me...
I need to say also that this equipment are not mine, i'm a teacher in
a university here in Chile (Santo Tomas), and i use this equipment for teaching
purpose.
I will wait to see if someone is using the same or similar
equipments that can tell me if this is just a limitation of the mixer or a miss
configuration problem.
Thanks.

I had a quick look on the Yamaha website and it looked like the mention of ADAT sync was
confusing me. I guess that you are using an ADAT optical coble from the DM2000 to the SDR
for word clock and sending start/stop/ff/rewind commands via MIDI. In that case
it is up to the SDR to report its position back to the DM2000 via MTC and, as already
said, it only does this in play or stop mode. If you sent MTC while previewing at high
speed you would rapidly run out of MIDI bandwidth because MTC sends one message every
quarter frame. Cheers. James.

James is correct. The problem is not the desk, it is that the SDR is not sending MTC
information other than when in play. It is quite normal, I'm afraid.

James, is only possible to send word clock sync by the adat optical cables, at least with
the sdr, for MMC i need to connect a serial connector or the midi cables, that is why i
have the midi for mmc and mtc. I've tried all the possible configurations. Hugh, thanks for the answer...and yes i talk with a friend that has a 02r and is
correct, the mixer is only capable of see the Time code when is in stop, is not able to
refresh the timecode in realtime.....seems like i will able to do that if i have a
recorder of the same brand or using an mlan compatible machine. For example the adat
machines when they are connected with the BRC. Is a big dissapointing having the
huge Time code display in the optional bridge of the DM2000  Thanks to all for the answers.

Look on the bright side. You have another argument to use when negotiating with the
university authorities why they must give you a bigger budget for better equipment

Yeah...but for the moment i think that i'm going to live with this little problem...at
least for the next 2 years or something, we bought the mixer just this year...and
personally i think that this desk is awesome... we've being thinking about the new icon
D-control or something...but is not a good deal, at least for teaching...because there are
not too many protools stations in my country...we have a Nuendo 3 DAW and the next year we
are thinking in implement a 5.1 facility with this console...but with this little problem
we will need to reconsider the equipment list. For music maybe is not so important the MTC
problem...but for POST...ufff.... Franco Sarrocchi Chile

Please read Hugh's comment above...
it's NOT the console.
it's
the mackie and the limitation of Midi bandwidth

Max, i know that is not the desk...i'm just talking in general about our current equipment
limitations.
Thanks.
