mpc 2500 jj osxl sync kontakt

Hi guys, im new in the forum and i want know how to assing different librarys of kontakt in different tracks of mpc.
now i sync mpc and kontakt i can open library 1 for example, i can rec this in track 1, good, but if i want open other library in other track and plays this at the same time that library 1, how is possible? Mi daw is cubase 8 element y mpc 2500 jjosxl. Thank for the peopkle that they want help me.

Each track in your MPC must output on a different MIDI channel, i.e 1A, 2A, 3A etc. Configure Kontakt so that each instrument is set to receive MIDI on a unique MIDI channel, so track 1 in the MPC (set to midi channel 1A) sends MIDI info to the Kontakt instrument set to receive MIDI on channel 1, and so on.

yes, i do it: mpc- track 1 midi 1A Kontakt- kick midi channel 1A
mpc- track 2 midi 2A kontakt- snare midi channel 2A (for example)
I'm recording in my mpc the midi notes of track 1,good, but if i record in track 2, the snare sound repite the kick, and the snare sound, only sounds if i select the sound of snare in my pc with the mouse, and the kick shut up... you understand me?
if i open kontakt and i choose one sound, assing to midi channel 2A in mi mpc midi 2A but not sound
kontakt only sounds when the channel is 1A and the mpc midi 1a,2a,3a,4a... how to configure better?
