syncing to protools delay??????

Sup all!

I have a quick question. I have my MPC 2000 synced as the master to Protools le 5.3.1. and everytime I record drums, everything is fine.
But when I go to record my bass lines and piano sounds, they is a major sync delay???

Has anyone had this problem? and can someone help me out???

And everytime I go to record these sounds the synce might be off just a hair off(but it's enough to tell) or the sync might be waaaayyy off....

Please help!!!!!!!

btw, I also tried using protools as the master and the same thing happens......

Sync how? You failed to mention.

MMC or Midi Time Code

yo wassup... I noticed u were havin problems with syncing to pro-tools. u might need to go into your playback engine and drop your sample rate to 256.. you should have no latency then.. let me know if it works.
