Yes, I realize that. However, it is overwriting them within the project folder. It should only have to collect and save “duplicates” of the samples once, when the project is first saved; but instead, it collects and resaves ALL the samples every time the project is saved, systematically overwriting each sample as it goes, even if nothing in the project’s sample pool has been changed. Again, unless samples have been added or otherwise deleted from the project, there should be nothing to resave, except parameter changes and sequencer data… Period.
The same is true of saving a drum program: i.e. the MPC initially collects and saves all the samples associated with the program, and stores them, in redundancy, in the program folder along with the program data. But, should you make any changes to that program, however small, and wish to save those changes, the MPC proceeds to overwrite ALL the samples in the program folder, even if the only thing you changed was, say, mixer levels or what have you. Hell, it even tells you that it’s going to “overwrite” them in the prompt that pops up.
As for the file format of the samples in question; they were all sampled directly into the MPC itself, so whatever the MPC does with files, that’s what format they are. The only reason I even have uncorrupted samples to replace the corrupt ones with, is because I saved all the samples to a separate folder, independent of the program and project folders, as I was sampling them. I’m thankful for that foresight now, let me tell you what!
Cheers!
