Reviews and questions about the entry-level MPC500

Hello, I'm having a problem and I'm hoping someone out there can shed some light on what might have happened.

I'm very careful to listen to my entire sequences and check that everything is in order before saving. I always use 'save entire mem. to AUTOLOAD'. I powered up the 500 today and a bunch of my samples were missing. In 3 programs, all samples are gone; about 20 samples total. All my other program's samples, as well as all sequence data is intact. When scrolling though the sample assignments in the affected programs, the names of the missing samples remain, but with a ? question mark next to the name.

In the session previous, I was working on adding notes to a sequence with step edit, and thats all. Didn't record any samples or mess around with those particular programs.

Is this ringing a bell with anyone? I don't know what the problem could be. I have the latest OS. "Status" button reads wav:57%, sq:94%. I'm not supposing this could be a RAM problem, correct? I have a 128 mb chip in there.

I just re-recorded all the missing samples, placed them in their their former locations, and my sequences now play like they should, as all sequence data was not affected. But it was a total pain to do, and now I'm worried this will happen again.

Thanks in advance!

Did you erase any samples and not resave the program or entire memory again? Did you rename something and afterwards didn't save entire memory again? Did you load that memory card into your computer and rename something somewhere? Think back.

Anytime you make ANY changes, you'll have to save entire memory again in order to update your saved stuff. Anytime and everytime, I can't stress that enough. No matter how small the change is, resave so that your program/project/seq will look for and load the proper filenames and samples.

I'm guessing you changed something but didn't save entire memory afterwards.

Thanks for the reply. I don't think I did any of that, but maybe accidentally something got changed before I powered off. Hopefully that is the case. From now on I'm going to listen to all sequences through before powering off, to make sure.

That would be a good practice to get into, lol.

Yeah, I save every 15 minutes on the 500. Autoload is cool and all but there needs to be an AutoSave!!!
