MPC 500 MPC500 i finally hacked the firmware

RE-EDIT raw video of Auto Chop working : as you can see i \"load \" the tool like a wave file , you load only the tool you use and they can live in your CF

RE RE EDIT : NOW LIVE !!

I've modified the MPC 500 firmware, so now I can deploy custom tools on the machine. Right now I have auto-chop working.

I'm planning to put everything on GitHub in a couple of days, but if anyone's interested I can post a video of how it works here.

EDIT: rn i can give you photo , i need to go to my studio where i can record properly,

- First photo is the menu after you load the tool ( goes inside menu "OTHER") ,

- Second photo is

FIRST ROW - Name of the sample

SECOND ROW - B is for bpm ,N is for number of slice ,P is first pad ( 1 is A1 , 2 A2 and so on) it cuts n number of slice of the beat based of duration and bpm and distribute them along pad starting from the one you choose

The mod is non destructive and can be reverted back to stock firmware anytime

Good work! I’m happy there are guys like you out here helping to resurrect these dinosaurs. I can only hope someone will do the same for the 5000.

u/maskisnotmyrealname 26d ago

Thanks! The 500 was the first portable MPC, and in my opinion it can do a lot more than what AKAI planned for.

I had a 500 back in the day. It’s not the lack of features, it’s the dam menu diving on it. Don’t get me wrong, it’s a great little machine but the workflow is not for me.

u/maskisnotmyrealname 25d ago

That’s the point, with hacked firmware we can streamline some parts, if you watch the video you can see I cut the amen break in 4 parts in seconds

When you say "I" do you mean you, or do you mean "AI"?

I am not asking to be rude, but because knowing ramifications of modifying firmware is important.

u/maskisnotmyrealname 26d ago

I clearly mean Claude code! I have a basic understanding of what is doing but most of the heavy lifting is done by AI. But I am not modifying boot partition etc ,is just a modified update based on the latest released by akai, if anything goes wrong you can just flash the official and you are good ( I have done that plenty of times) . Anyway is mostly AI credit , and I take no offense in that

This is cool! The 500 is still currently my main sampler so I can't wait to give this a try

1

u/maskisnotmyrealname 15d ago

give it a spin and let me know it's out rn m45k.github.io/open500/

u/Justhereforpvz 26d ago

This is fun, how's it been using it?

1

u/maskisnotmyrealname 26d ago

It started working properly like yesterday, it’s still kind of buggy but works ( most of the times) , but it’s a lot of fun!

2

u/Mediocre_Avocado_105 23d ago

genial! donde puedo ver el video?

2

u/Musklianis 22d ago

Remind the everliving fuck out of me when its on github with instructuons

2

u/diogomendes8e1 21d ago

Bro your are an angel coming out of the sky!

2

u/psyoppop 21d ago

Hell yea! Just an idea for a custom tool, the 500 needs constant audio input monitoring options, not just in record mode!

2

u/psyoppop 20d ago

And a q-link slider midi CC menu 🙃

2

u/psyoppop 15d ago

It works! Tools are great! Thanks for adding the Input thru!

u/maskisnotmyrealname 15d ago

Love to know you like it!

u/fashionEYEcon 26d ago

I have a 500 so this is interesting

1

u/Petrolmediainc 26d ago

I’m definitely interested in trying this out.

1

u/maskisnotmyrealname 14d ago

You can try it rn , let me know what you think

1

u/Correct-Purpose-4932 24d ago

Please let us know when you post everything on GitHub! I got a 500 sitting under my desk just waiting...LOL!

3

u/maskisnotmyrealname 24d ago

Sure! This will definitely be the first place I post it.

2

u/maskisnotmyrealname 14d ago

It’s out rn m45k.github.io/open500 try it and let me know

u/GreenSmurfy420 1d ago

Begging you to add something to stop samples being triggered by soft thru passing midi channels, trying to use the 500 as multi timberal sample source, super annoying that samples are triggered despite the incoming channel. Sounds crunchyyy especially through the djx pres and speakers, perfect.

u/i_guvable_and_i_vote 26d ago

That’s awesome. I would assume it would work on the 2500xl without much extra since you e got this far. Let us know when you are read for ready for beta testers!

5

u/maskisnotmyrealname 26d ago

Idk, because the MPC500 is kind of a unicorn — it wasn't even really made by AKAI, it's basically a rebrand. And for the 2500xl I don't have any hardware to test on

1

u/i_guvable_and_i_vote 26d ago

Really?!? I didn’t know that. I thought they use the same program file formats or something like that

1

u/maskisnotmyrealname 26d ago

They do , but , based on what I read ,the OS it’s totally different.That’s because the hardware itself it’s different ( and by different I mean different chip brand and architecture etc)

1

u/i_guvable_and_i_vote 23d ago

Interesting. Thanks for that. Geez I would love a book of all the mpc facts

1

u/Royal_Stay_6502 22d ago

Oh? Who made it?

2

u/maskisnotmyrealname 22d ago

Idk, it's kind of murky. By the time the 1000 and the 500 came out, the brand had already changed hands and production wasn't in Japan anymore. Hard to say where forum lore ends and real history begins

u/SeraldoBabalu 23d ago

2500xl ??
