weird MPC SYNC problem...

hmmm./.. not at home... ill check it later.

Btw, im recording using the system hard drive. It's highly recommended to get an additional HDD but i dont have one. could this be the root of my problem?

WEll,

in general, yes.

latency is THE cause of whats happening, whether its midi port input latency or just general CPU latency. thats the point of having really fast computers.

my tower is the slowest G5 ever built, but even with 4 gigs of ram, i can clip out CPU in a larger session. Thats why I always track vocals to a bounced 2 track.

if you have the whole session for the beat, and its spinnin wheels on 40 plug ins, your vocals are going to record late regardless, and get worse as you add layers.


But back to midi..

Which interface do you have again?



The way I see it theres two ways about it...

you can either run the whole session a consistent amount off grid, and ignore the nudge factor until it becomes critical... and then chop all of the fronts off at once and slide everything to grid...

or, you start narrowing down whats causing the latency....


long cable runs?

cpu latency?

stuff like that... if your locked on time code, and your machine is chasing your protools grid, then the latency can just be adjusted... as above.

or you can see of you can mess with your playback buffer, midi offset, and all of that,

ill play around.

"mbox 2" - not pro, not mini.
i keep all cables under 10 feet although midi cords might be a BIT longer than that.

im on pc - win xp home
ahtlon x2 3800+, 2gb ram

I was wrong. I said I didnt have any problems when I set up Pro Tools as a sequencer. That was bull b/c I checked again. There is a delay. The very same one. I turned the sync off and tried using the mpc as a sound module. All midi data was in pro tools. That didnt help AT ALL. That's REAL WEIRD because Pro Tools is a sequencer and it just records AUDIO????? Sync is OFF, PT just triggers the sounds on the MPC.

AND it does NOT matter if i record sounds from the MPC or MOTIF or FANTOM or whatever I plug in. NONE of those instruments are connected directly to the MPC. All are connected to PRO TOOLS via MBOX2 and USB (some use midi, some usb -- not both). And so is the MPC. the delay is always the same.

I played around with the H/W Buffer and 256 samples was a PERFECT choice (knock wood). It's in SETUP > PLAYBACK ENGINE (to those who might have that problem). 128 samples and 64 did NOT work for me. It was better than my default 512 samples but there still was a lag. Im no computer scientist but this might be because my pc aint strong enough??? So I chose 256 and everything seems to be on beat. THANKS FOR THE HELP YALL.
CASE CLOSED.

Yeah. that was my point earlier about hardware buffer = latency.

It is the time it takes to process the sound, send the data, etc.

there will be times when you have to increase the buffer size to allow for more processing power of plug ins.

good job for keeping on it though.


now mess with the fine tune on the midi offset.
