Pgm changes automatically

I copied my sequence 1 onto sequence 2, in order to mute some sounds for change ups. Now heres my problem, when i change sequences in play mode the Pgm changes automatically (Pgm 1 drum hits) (Pgm 2 horns, guitar etc..) from Pgm 2 to Pgm 1 on one of my tracks changing the sound thats normally suppose to be played into a kick drum.. Remeber I copied the sequence so they are identical sequences. Hopefully i was clear on my problem and would appreciate any help.. peace

you've obviously **** up somehwere. check your pgm assignments. and re-copy the seq...

tried that..also tried open window on Pgm and turned changes off..still cant seem to find out whats goin on
