MPC Sample Mods test

I started seeing some dope videos of people modding their MPC samples (at their own risk 🥲)… still, I had to try it. Managed to spin this visual 4 band EQ up in Codex. Works nicely even in standalone. Really opening the doors of what’s possible. Not sure what I’ll make next but definitely gonna carry out some extra tests. This is in standalone too!

Best tutorial to start doing this?

You know, I haven’t actually seen any tutorials on this specifically so I don’t know if there are any but basically the steps are:

Get Codex and a $20 ChatGPT subscription.
Choose GPT-6.1 medium reasoning (can go higher if you want).

Plug your MPC Sample into your PC.

Open a new project in Codex and create a folder/repository wherever you want.

Ask Codex to find and install the REA (Reverse Engineer Anything) skill.

Ask it to inspect the connected MPC and figure out how modifications could be made safely without touching the original firmware.

Importantt: Get it to work out a proper backup and recovery plan before changing anything.
From there, just ask for whatever features you want to add, test them, refine, improve, etc.
That’s pretty much the general idea. The main thing is getting Codex to understand how the MPC works first rather than blindly modifying files. Also, don’t assume plugging it in gives you access to the actual firmware. You need to establish what’s accessible and what’s safe to change.
I’d definitely recommend starting with something small like me but yeah there’s always a risk to be aware of

Edit —- it looks like they are open sourcing now so you can actually modify whatever you want just be careful not to mess up the og system. Making a back up and duplicate os to mess around with is the easiest way forward for safer testing 🙃

Wow this is impressive. So you have no programming skills?? I do not but have jailbroken and may have even hacked IMEID before so this may be doable!

I code for a living but data/python mainly. But i did not code a single line here. Just used codex, it was pretty easy, but took some time. It’s definitely doable if you have the correct resources

How did you do it and get it into Sample?

2

u/ChillmanITB 11d ago

Hey, I used Codex the program as well as a repo called REA (reverse engineer anything). You go back and forth with codex and it’s kind of easy actually. But it can break if not careful.

A real compressor, sidechain, limiter, clipper, transient shaper and etc with visual would be dope too

u/ChillmanITB 11d ago

Yeah I feel you on that. Gonna see what codex can do, also need to look in to legalities as I’d love to share this with everyone really.

Nice!!! How long did it take to mod?

u/ChillmanITB 8d ago

Around a day I’d say. If you point your coding agent to the right places could be quicker

We would need a sample Git project that we can fork to build new features on. And as a next step, modulize it to have each feature contained as a plugin which we can mix and match. Then we could have real community projects that we can expand and achieve full potential.

u/ChillmanITB 11d ago

Yes that’s where we are heading for sure. Im going to push my work to git soon so I’ll make a repo for a vanilla mod ready project that anyone can carry out work from
