midi sync mpc/terratec dmx6 fire

anyone using a terratec dmx6 fire with the mpc ?

i've some problems of synchronisation between the mpc and cubase... Cubase is set as master and mpc as slave, when i try to record a track cubase start recording and the mpc start reading but the tempo slows down it seems that it reads the mpc sequences at about 120 bpm but in cubase the tempo is set a 138 ? I had a soundblaster pci 512 before and i didn't get any problem... i use windows 98 se and cubase vst 5.0.

Help please !!!

not sure, but make sure the timing frame rate is set to the same value on the mpc and cubase. tempo/sync on the mpc and sync screen in cubase.
