cmon...someone back me up on this...it is definately possibly, i had to use 5 programs one time on a beat....i either read it in the manual or somewhere on this site, but basically in the program screen with the program name highlighted (pgm:), hit open window and under midi program change theres a number, u gotta number each program a different number, and then u go to the main screen and highlight the pgm: thing hit open window and switch it to yes, it says somethin like transit program changes? anyways if u use the data wheel it scrolls thru the numbers 1-24, each number corresponds to the program which u set the number for earlier in the program screen......maybe i mispoke/misunderstood....u can use mor ethan 4 programs throughout an entire beat, but only drum 1-4 simultaneaously, i think itll change whatever drum 1-4 u have selected on the track and change the program to whatever number u set it to.....im not bullshittin yall, if u really dont believe me try it out sometime.....like i said tho it gets confusing and it **** up sometimes, i would say its much easier to jus keep it to 4 programs total

just found this...the last post from MPC TUTOR HIMSELF....
"Make sure you read up about program changes. This allows you to use all 24 programs in one sequence if you want - just fire off a program change event in step edit when you want to change the program assigned to the DRUM holder on that track."
