I hoped the latest update of T2 ".13" would fix MIDI. I actually went back to Cubase 5 just to import from the VS-1880 due to Mid Sync timing problems. I then bring the files into T2. I hate Cubase 5's non-user interface but at least its MIDI MTC sync and MMC is rock-solid.

My Config: VS-1880 Emu 1880m.

I've been trying to sync T2 with my VS-1880. It does not work well (the result is unacceptable). Using analog inputs (I removed SPDIF dataclock as a possible issue) I have tried the VS-1880 as MMC master sending MTC and I have tried the T2 sending MMC with VS-1880 set to EXT sync MTC. I have tried all combinations of those (T2 sending MMC with VS sending MTC). All produce a warbling audio with some combinations worse than others. If it sounds good for a few seconds just move a scroll bar on T2 - it will slow the audio. I also get audio clicking with some combinations.
Does anyone else have these problems?

The problem where I press PLAY on the the VS-1880 but I want the T2 to RECORD is a secondary issue at this point.

There is a problem recording audio when Tracktion is synced as slave (I've reported it to the proper people) but if I remember right I got good results the other way round.. but if your '1880 is anything like my old '880 it is quite easy to miss a setting.

Make sure Tracktion is sending MTC and MMC, but responding to neither. The VS will need to be set up as MTC and MMC slave (these are in different menus on mine

) and you need to make sure the frame rate is set the same for both.

Hi, Thanks for the response. I tried it again just to be sure and double checked everything again (I've been working this issue for many days.)

I also checked some VS forums. The setup you recommend works the best (and will probably work for most devices) but, thanks possibly to some (I read on the web) interactions with the VS - still has problems. If I have the Mackie FinalMix loaded it is really bad (sounds like dragging a finger on a record). It appears that if T2 is late getting MIDI info to the Roland, the Roland will adjust its varispeed (even though it is not ON) to compensate. I don't know if that is true but that is what the vs forum-folks said and that is what it sounds like. The result is warbly audio even though T2 is not following MTC. I do not have that problem with Cubase or Adobe audition.

Just to be sure, I optimized Windows XP (as per several Web articles) and removed all VSTs from T2, stopped scrolling, selected Real-Time Priority Mode etc. Now the problem is more subtle, but still there. Not good enough to use.

Thanks,

By monitoring at the VS-1880 I verified that the Roland VS-1880 is indeed slowing down/speeding up due to the MIDI info given by T2. This is the only software I have had this problem with, so I have to blame T2 even if the Roland is doing something wierd trying to adjust to the mis-timed Midi data it receives.

I got jitter when slaving T2 to MTC aswell, from an ADAT. They say this is normal though, and what we need is ASIO2 sync for T2.

Here was the results, same signal recorded realtime, ADAT and T2 side by side.

I'm getting my VS-1680 to sync with T2 finally. T2 is master and the VS is slave. I can also get the VS to follow along with T2's cursor when either using the mouse to drag it or else using T2's transport controls. But here's the catch: the VS only responds to MTC and not MIDI Clock, so viewing everything based on bars and measures is out the door. The two sync based on frames and subframes (I set the MTC sync type to 24 in both units). Also, here's another catch: when T2 is at 00:00:00:00:00 the VS is at 00:00:00:01:27. There is exactly a "1:27" difference in the two units' positions throughout playback and wherever I stop T2 the 1:27 difference is still there. I'm assuming that some sort of timecode offset needs to be implemented in either T2 or else the VS but so far I haven't found the right numbers. I can adjust either unit but the formulas that the VS's manual suggest for figuring out the offset amount is confusing. Any help on this would be most appreciated. I haven't had a chance to do any real monitoring on recordings and how well they actually do sync up from a listening perspective......I'm just going by the numbers in front of me.

You can still do it, you just need to make sure the VS has the correct tempo settings.. if these fluctuate I think you can record a tempo map on the VS so it changes at the same time. (I'm pretty sure I can do that on my VS-880 anyway, so should be possible on your '1880)

Great news about your success syncing with VS-1680! Could you try loading FinalMix and monitoring through T2 to see if you can reproduce the problem I am having? FinalMix seems to make my problem more noticable.
Thanks,

Thanks,

Actually I started another thread a few days ago that pointed towards Final Mix having these issues since the latest T2 update. You are not alone:

T2 only seems to send out PLAY, REC, STOP, MMC commands? Anyone else experience this? My AKAI MPC 2000xl will only respond to these.

Im making T2 the master here on advice in this thread after some problems with my AKAI MPC as the master? Other than that it seems to sync nicely with almost totally in-audable slight phasing with no MTC offset.
