midiclock is a drag!

Hello Yall.
I got the following prpblem today:Synking my MPC 2000classic to my Emu XL-7 or whatever the thing is called with midi clock and the following happens:the Emu drags behind just a little and everything it plays is just a tad off.
I first thougth this was because of the emu being slow,but I start to rethink this.My MPC have shown signs of being not tight while using the midi clock before.Try recording while sending clock and there will be a nasty lag at the first beat of the first bar,to name one clokrelated problem I have.
Have anyone found a way around this? Is is a os or a hardware problem?
Is it any better in the XL or 1000 model?
Peace holger honda

insert a measure in your mpc sequence so that it give the device time to synchronize each other and see if you can use MTC/MMC also. Midi clock is not accurate sometimes. MTC/MMC is good for synchronizing midi devices.
