WHY DO I HAVE TO REPLACE A SONG TO LOAD ANOTHER!!!

There is nothing you can do about the replacing the *.all file. The only thing you can do in that situation is to load all of your sequences into the same *.all file.

As for the samples and programs you're really just limited by the amount of RAM you have available (shift 4 + open window). You can load many different programs into the mpc so long as you don't keep saving them as *.APS files. Well if you do have a set or something prepared with all the programs you'll use then save as a *.APS file other than that just save as a *.PGM file.

Another thing to keep in mind is which program is used for what sequence and what programs are assigned to the drum banks. Once you have your *.all file with all your sequences you can start adding program changes to your sequences allowing you to switch switch sequences without without having to go through menus to get the programs to switch as well. Having all your programs in one *.APS file with your program changes in your sequences will be the solution your looking for. It does mean that you'll have to input a different program change number to each program and organize those program changes to affect the right drum bank within the sequence.

here is a post done recently about the topic of program changes.

As far as putting program changes in, you can do that through step edit. You should put the program change, if possible, two steps before the end of the last sequence before the program change is needed. Alot of times it takes a few seconds to get the program changed completly and most people have sounds hitting right at the begining of their sequences.. so a program change there isn't much help

Hope that didn't confuse you too much,

P.S an easy way of loading all your sequences together is by adding to an exsisting one and resaving it as something else. Also, to load other sequences from other *.all files into your new *.all file just hit <seg> instead of load when doing your regular *.all file loading process. It might take a little time if you have alot of sequences to load.
