a plee for help

I am trying to use Cubase with my MPC 2500 , i want to use my VST's as sound modules. But if I have more than one VST the MPC seems to send signals down all the midi channels playing all the VST at the same time even though they are all on different channels can any one help.

I have my MPC sync to Cubase as the master, MPC settings are all correct
my midi routing is as follows

Midi keyboard out to MPC midi in A
MPC midi in to PC sound card midi out
MPC midi out A to pc sound card in

settings in MPC

MIDI
active track receive channel ALL
softe thru AS TRACK
sequence change by program change OFF
pad to internal sound ON

main window
track01
type MIDI
pgm OFF
midi 1A

track02
type MIDI
pgm OFF
midi 2A

You have to make the necessary changes in Cubase. You can set each track/VST instrument to respond to 1 MIDI channel. If you have one of the lastest versions of Cubase, you would do this with the Input Transformer.
