me problem with akai mpc 2000 xl

I have connect with me akai midi a synth yamaha dx200.

now working with a midi track, I send notes to the synth sound from akai and all ok, recorded etc ... all perfect ... but I have a problem ....
I assign sounds of drums that I have on file in the SCSI, and when I assign a sound of SCSI sample (for example KICK 909) to a pad on the akai pad .. to be connected to the synth midi ... the sound of the synth sounds that corresponds to that key and also the 909 KICK that I assigned to that key ....

That I want is record a 4x4 loop with 909 kick, and then reproduce the sound of the synth for MIDI,,, but I can´T GET !!!!
because when the akai reproduce the loop with 909 kick sounds also sends the MIDI notes to the synth yamaha for midi ... and this made two sound 909 kick + note MIDI corresponding of a Pad


is very difficult for me to explain this problem so that you will understand because I have a bad English.

sorry, and thanks for your help

Try putting the kick on a different pad, or a seperate program for the drums, maybe?

Can you explain me a little, as seperate program for the drums???

thanks
