Post your views and questions about the Akai MPC2500

So I know what the response will be from lurking on this forum for a while but I am not looking to install JJOS.

For the rest of you that are still reading this and have experience with the original 2500 OS:

Have any of you experienced this? I save a program, I save a sequence, but when I turn the machine back on I go to play the sequence and each track is defaulted to the Program1. I have to go and change each track to the appropriate program. This is mad annoying and possibly something that would be solved by updating to the most recent akai OS but I have a real concern that if I get into that I'll **** my MPC up. The eject button for the CF card is missing and I would prefer not to remove it, that's why I just want to keep things as is.

I couldn't bear it if I bricked my MPC due to my technical inabilities.

Just to rule out the obvious, how are you saving? I don't remember what it's called exactly on the Akai OS but make sure you save the 'Entire Memory' instead of just the programs/sequences individually.

With regards to your eject button not working, there is a workaround. Install an SSD/HDD/CF card into the internal slot and transfer a new OS to it via USB. That way you don't have to use the external slot.

Also the chances of 'bricking' your MPC are pretty slim as long as you follow instructions. I know this isn't the answer you're looking for but if you stick to Akai OS, these are the kinds of problems you might run into.

Thanks for replying. I'll start using save entire memory. I was using it before I really knew what I was doing, with limited results. I didn't have my sequences and programs named so I was making it confusing for myself. Basically, saving the entire memory is like a snapshot of the whole project, right?

I'm not sure I understand the difference between the internal slot and the external slot. I have a CF card in the slot with the broken eject button. Could I just transfer the OS to that card? And after I install it I will have to reformat the CF card, correct?

Yeah, saving the entire memory is just a surefire way of getting everything saved. It might do the trick for you.

As for the internal/external slot there's no difference really. You could also transfer the OS to the external one via USB. I recommend you give it a go simply because you can always go back.

I could be wrong but I think you're supposed to load a new o.s. from the cf card.

And, yeah the best way to save and not make things a mess is to create a new folder each time and then save entire memory in that new folder. At least thats how I always do it.

correct - os updates (whether akai or jj) have to be transferred from cpu to cf via usb, then loaded either on startup or via load.

chances are akai or jjos upgrade won't mess anything up on your machine. i ran both the most recent akai and am now on jjos 3.13, no issues.

also, +1 on phx's suggestion on saving entire memory to new folders. i do the same. just create a sub folder with projects, then create new folders to that with your individual projects. this way you won't have potential overlap. also, naming your programs, tracks, sequences, etc helps to ensure you aren't duplicating.

as an example - if you're saving projects to the same folder, you could end up with overlap if you don't rename your programs. if you're just using default program names, it'll overwrite your previous programs with whatever program you save.

creating individual folders for each project bypasses this. as you said - essentially creating a snapshot.
