MIDI SYNC: the ultimate SYNC thread

I'm not trying to discredit my man Jah,But one of the Prime Sync issues is Optimizing your PC's.Remember System Performance has alot to do with how Daw's Perform under a body of Audio and Midi work. There is so many things to tie in to sync issues with Daw recordings and that's on any Software. So I would suggest first,make sure that Your PC or I-Mac can handle the work load of Audio and Midi sync in recording. Also don't forget that Memory and harddrives can play an important part to. There's a butt load of things to check for when Opting your PC,Oh can't forget to check your settings in the Virtual Memory Area that's number 1 pending on if your using one or more drives and where your recording to. I'm jus saying After I learnt and did my home work I lesson the sync issues with my MPC's and Softwares,I can run any MPC with any OS and not have any problem. I believe Jah's Trouble shooting (O.S) plays a vital part in hardware and software sync issues.

yeah i hear what you're saying DJ-T... but the mpc midi beat clock sync (slave) is off on OS 1.2, 1.21, and 1.22. the MPC plays early using these operating systems.

and i don't have any issues with optimizing my system performace i'm running a mac with protools HD.

it's supposed to work right and it doesn't. that's why i have to use OS1.1 until they fix it. 1.1 works fine in midi beat clock mode. unfortunately it aparently has some midi bugs that affect other users.

ok well...... I understand,I still think that in elimanating the sync issues with the PC down to the OS can help better discover the main top which jah has narrowed down,you guys have to better find a easyier work around. And to I forgot to mention that Latency can be a big problem with syncing.But Hopefully Akai will do something before or After the Namm show.

Well, you should use MTC to sync...or use the MPC as the Master.

MTC is the most stable using Akai OS 1.22. If you look at my original MIDI sequence that was imported into Nuendo..and then comapre it with the MIDI sequence recorded into Nuendo using MPC 2500/OS1.22....the drum hits were exactky .010 seconds off from one another consistently throughout...and remember this test was not using a computer. I used the MPC 3000.

Also note that Pro Tools is a good audio application...but its MIDI features has lagged behind other DAWs for some time now. Its hardly the ideal system for MIDI.

And that waas my next comment on MTC.Your Right MTC is the most stable
controled protocal in using midi messages. I'm just saying in my earlier comments......as you narrow down the main issues concerning syncing,you then can move on to the different bug issues using the Akai's O.S's . And again there is more than one way to work around the bug problem in the Syncing issue with 1.22 or 1.20 or whatever.
So I think Jah is doing a good job in proving his theory in delays, using different hardwares and etc.

To me it jus seems everybody is just stuck on Midi Clock,and not experimenting with other midi syncing codes. Now this is in reference to all the comments made before by other USer's.

Besides some sync issues/non-issues....there are no reproducable errors that I am aware of. I do hear other forum members talk about bugs, but no one can reproduce them.....

most of the user's in here need to use MTC feature more,to me it's the tightest sync protocal, hope that AKai fix that bug .

Well, I just use my ears and analog staff without computer and I can say that the midi clock on the 2500 with the latest Akai OS is not "on the beat", the notes are played BEFORE time. With the JJ OS it plays in time with the other hardware.

I don't use MTC or MMC.

My 5 cents.

Problem I have is I can hook my MPC up to Reason 3 (not in Rewire mode) and get perfect sync. All you have to do is click the little midi button on the Reason sequencer, set MPC to send to the appropriate out, hit play on the MPC and you get PERFECT sync. Then when you try to do the same thing to DAW (PT or Cubase) I can never get sync right. I had the same problem with my MV8000. Don't know what it is, but these DAWs do something different than Reason when processing sync, even when using beat clock, which is what Reason is using. So its not system performance on my Macbook or the MPC because I can get Reason to sync perfectly with ease. But when the DAW is introduced all hell breaks loose. So I've dumped sync and just record raw at a set tempo on the MPC and DAW and then trim to 8 bars, because that's about as long as I can get the two to tempo sync without the tempo drifting. One Love.

There must be something wrong with your DAW or Rewire..because they should work properly. Make sure that you have the latest OS for all software applications.

When using Midi Clock, make sure that your MPCs and software tempo matches. They usuallly default to 120 BPM...so make the proper adjustments.


CV-Gate...I feel you...and I hear what you are saying. But numbers don't lie. Also, as I pointed out in an earlier thread, the buffer settings of your computer will impact your results. Under these tests, I kept the same settings throughout. With my test, I set the buffers to 256 with a 6ms latency.

I thought it was jus me jah,but I've never had issues with Reason or Protools or A.A 1.5 or Cool Edit Pro 2.0 or Cubas SX 3.0 etc and again your right on buffer setting and Latency.....

it has nothing to do with latency if you have three drum machine's linked to the same midi beat clock and the mpc2500 is running ahead of the beat if you are using OS1.2, 1.21, or 1.22 but it locks correctly when you are synced using OS1.1 or the earlier OS's.

it's just off they need to fix it.

I'm not saying that the OS is fine, and don't need fixing.I'm jus saying and Jah is saying that setting your buffer's and Latency do play a intrical part in Audio Syncing hopefully Akai will get of their lazy butts and fix the MTC issues.
